[0025] Preferred embodiments of the selected apparatus and method of the present invention are described below with reference to the accompanying drawings.

[0026] [Implementation Method]

[0027] Before explaining the selection of device 10 and the selection method, for ease of understanding, we will first explain the aspects that should be considered when determining the arrangement order of amplifiers 14. In the following description, we will take the case of using bus 12 as an accessory as an example.

[0028] Figure 1A This is a schematic diagram showing two amplifiers 14 connected via bus 12.

[0029] Busbar 12 is a component used to electrically connect multiple amplifiers 14 to each other. Busbar 12 is one of the accessories in this embodiment. As described later, there are at least a variety of busbars 12 with different lengths or thicknesses. In addition, accessories other than busbar 12 are described later in the variations.

[0030] Amplifier 14 is a drive device for supplying current to motor 16. Furthermore, amplifier 14 in this embodiment includes a converter and an inverter. However, in the following description, unless otherwise specified, the converter and inverter are not distinguished from each other.

[0031] Figure 1A The axes representing the width direction (+W direction and -W direction) are shown. Figure 1A The +W direction in the equation is a direction along that axis. Figure 1A The -W direction is opposite to the +W direction. Additionally, the width direction can also be adjusted as needed. Figure 1A Other than those shown in the accompanying drawings. Amplifier 14 has a connection portion 18 (see reference). Figure 1AThe connection portion 18 is a power connection portion connected to the busbar 12. An amplifier 14 has two connection portions 18. The two connection portions 18 have a positive-side connection portion 18+ and a negative-side connection portion 18-. The amplifier 14 has a face (front) with the two connection portions 18. The two connection portions 18 are positioned at predetermined locations on the front of the amplifier 14. The two connection portions 18 are positioned at a predetermined distance from the end in the -W direction of the front of the amplifier 14 along the width direction of the amplifier 14. Additionally, the connection portion 18+ is positioned at a predetermined distance from the upper end of the front of the amplifier 14 along the height direction of the amplifier 14. The connection portion 18- is also positioned at a predetermined distance from the upper end of the front of the amplifier 14 along the height direction of the amplifier 14. However, the height directions of the connection portions 18+ and 18- are different. Figure 1A In the example, the connecting part 18+ is located above the connecting part 18-. However, the connecting part 18- can also be positioned above the connecting part 18+.

[0032] In addition, such as Figure 1A and Figure 1B As shown, in this embodiment, the connection portion 18 is described as being located near the end in the -W direction of the amplifier 14. However, the connection portion 18 may also be located near the end in the +W direction of the amplifier 14.

[0033] The front faces of multiple amplifiers 14 are oriented in the same direction (see reference). Figure 1A For convenience, the amplifier 14 on the -W direction side of two adjacent amplifiers 14 connected by the same busbar 12 in the width direction will also be referred to as "connection source". Similarly, for the same reason, the amplifier 14 on the +W direction side of the two amplifiers 14 will also be referred to as "connection destination". In this embodiment, the connection portion 18 is provided on the front of each amplifier 14 near the end in the -W direction. Therefore, the busbar 12 crosses the connection source in the width direction (see...). Figure 1A ).

[0034] Two buses 12 are connected to two connection portions 18 of each connection source and connection destination. Thus, the connection source and connection destination are interconnected. In this embodiment, two buses 12 are used when connecting two amplifiers 14. One of the two buses 12 connects the connection portions 18+ of the two amplifiers 14 together. The other bus 12 connects the connection portions 18- of the two amplifiers 14 together. In this state, the connection source (converter) is connected to the power supply P. Thus, current can be supplied from the power supply P to the connection source. Current is supplied from the connection source (converter) to the connection destination (inverter) via the two buses 12.

[0035] Figure 1B This is a schematic diagram showing three amplifiers 14 connected via bus 12.

[0036] exist Figure 1A In the example, there are two amplifiers 14, but there can also be three or more amplifiers 14. For example, as... Figure 1B As shown, three amplifiers 14 are arranged side-by-side in the width direction. Among the three amplifiers 14, the amplifier 14 located in the -W direction and the central amplifier 14 are interconnected via a bus 12. Additionally, among the three amplifiers 14, the central amplifier 14 and the amplifier 14 located in the +W direction are interconnected via different buses 12. In the relationship between the central amplifier 14 and the amplifier 14 located in the -W direction relative to the central amplifier 14, the amplifier 14 located in the -W direction is the connection source of the bus 12. Furthermore, in this relationship, the central amplifier 14 is the connection destination of the bus 12. Additionally, in the relationship between the central amplifier 14 and the amplifier 14 located in the +W direction relative to the central amplifier 14, the central amplifier 14 is the connection source of the bus 12. Furthermore, in this relationship, the amplifier 14 located in the +W direction is the connection destination of the bus 12.

[0037] When multiple amplifiers 14 are connected via bus 12, the appropriate bus 12 varies depending on the arrangement order of the multiple amplifiers 14. The amplifiers 14 can be of various widths. As described above, bus 12 traverses the connection source in the width direction. Therefore, the length of bus 12 must be at least the length from the connection portion 18 of the connection source traversing the connection source in the width direction to the connection portion 18 of the connection destination. However, from the viewpoint of achieving the connection of multiple amplifiers 14 in the most compact configuration possible, it is not preferable to use a bus 12 whose length is excessively greater than the distance between the two connection portions 18. Furthermore, large bus 12s tend to be more expensive than small bus 12s. Therefore, large bus 12s are more costly than small bus 12s. For this reason, in selecting bus 12, it is preferable to select a bus 12 with the minimum required length to connect the connection portion 18 of the connection source and the connection portion 18 of the connection destination.

[0038] Figure 2 This is a schematic diagram illustrating how the types of busbars 12 vary depending on the arrangement order of amplifiers 14.

[0039] Sometimes the widths of the multiple amplifiers 14 are not the same. In this case, the minimum length of the busbar 12 that connects the connection portion 18 of the connection source and the connection portion 18 of the connection destination varies depending on the arrangement order of the multiple amplifiers 14. A specific example is... Figure 2 As shown in [the image]. Figure 2The upper and lower sections illustrate groups of two amplifiers 14 (amplifier 14X and amplifier 14Y) with different widths. The upper amplifier 14X and the lower amplifier 14X are the same amplifier 14. The upper amplifier 14Y and the lower amplifier 14Y are the same amplifier 14. Figure 2 The upper and lower sections of the amplifier 14X and amplifier 14Y are arranged in different orders. Here, a comparison... Figure 2 As can be seen from the upper and lower sections, when the arrangement order of two amplifiers 14 with different widths is changed, the minimum required length of the bus 12 used will also change. Figure 2 The arrangement of the lower segment, compared to the arrangement of the upper segment, allows for the connection of amplifiers 14X and 14Y using a shorter busbar 12. In this respect, Figure 2 The order of the lower paragraphs is more than Figure 2 The preferred order of the upper section.

[0040] Furthermore, a thicker busbar 12 can withstand a larger rated current. Therefore, the busbar 12 connected to an amplifier 14 with a large rated current should ideally be thicker. Additionally, amplifier 14 tends to be designed to be wider as its rated current increases. Therefore, the busbar 12 connected to a wider amplifier 14 tends to be thicker. Furthermore, when the power supply P, busbar 12, and another busbar 12 are sequentially electrically connected, it is preferable that the thickness of the former's busbar 12 is greater than that of the latter's busbar 12. This ensures a stable current supply to the latter's busbar 12.

[0041] Thus, after selecting amplifier 14, it is necessary to further select the accessories (busbar 12) connected to the selected amplifier (selected amplifier) ​​14. However, the types of accessories connected to the selected amplifier 14 vary depending on the arrangement order of the multiple selected amplifiers 14. Therefore, in order to properly select the accessories connected to the multiple selected amplifiers 14, it is necessary to select the appropriate arrangement order of the multiple selected amplifiers 14.

[0042] Based on the above preliminary description, the selection device 10 and selection method of this embodiment will be described below. In the following description, the case in which multiple amplifiers 14 arranged side by side in the width direction of amplifier 14 are interconnected by one or more busbars 12 will also be referred to as "parallel connection".

[0043] Figure 3 This is a schematic configuration diagram of the selected device 10 in the embodiment.

[0044] The selection device 10 in this embodiment is an electronic device (computer) provided for appropriately selecting the arrangement order of the plurality of amplifiers 14. For example... Figure 3As shown, the selected device 10 includes a display unit 20, an operation unit (input unit) 22, a storage unit 24, and an arithmetic unit 26.

[0045] The display 20 enables the selected device 10 to display information. The display unit 20, for example, comprises a display screen 20a with a liquid crystal (see reference). Figure 6 The display 20a is composed of a liquid crystal display. However, the display screen 20a is not limited to a liquid crystal display. The display screen 20a may be, for example, an organic EL (OEL) display.

[0046] The operation unit 22 enables the operator to input information (instructions) to the selected device 10. The operation unit 22 may consist of, for example, a keyboard and a mouse. However, the operation unit 22 is not limited to having a keyboard and a mouse. The operation unit 22 may, for example, include a touch panel. The touch panel may be provided on, for example, the display screen 20a.

[0047] The storage unit 24 enables the selected device 10 to store information. The storage unit 24 is, for example, a memory including RAM (Random Access Memory) and ROM (Read Only Memory). The storage unit 24 stores a predetermined program in advance. Such a predetermined program may include, for example, a selection program 28. The selection program 28 is a program for causing the selected device 10 to execute a selection method that appropriately selects the arrangement order of the plurality of amplifiers 14.

[0048] The storage unit 24 stores various amplifiers 14 and various accessories that can be connected to the amplifiers 14. For example, the storage unit 24 stores information referred to as the first table 30 and information referred to as the second table 32 in this embodiment.

[0049] Figure 4 This is a configuration example of the first table 30 stored in the storage unit 24.

[0050] like Figure 4 As shown, the first table 30 is a table that corresponds various types of buses 12 to the types of connection sources and connection destinations, respectively. The various buses 12 have different lengths, at least for connecting multiple amplifiers 14 in parallel. For each of the multiple buses 12, the first table 30 maps the connection source, the connection destination, and the minimum length required to connect the connection source and the connection destination.

[0051] Reference Figure 4In Table 30, for example, bus 12A has a length of 60 mm. The connection source of bus 12A is an amplifier 14 that is 60 mm wide. The connection destination of bus 12A is not particularly limited. Alternatively, for example, bus 12C has a length of 150 mm. The connection source of bus 12C is an amplifier 14 that is 150 mm wide. The connection destination of bus 12C is an amplifier 14 other than an amplifier 14 with a width of 300 mm.

[0052] Furthermore, in this embodiment, the thickness of the bus 12 can vary depending on the type of amplifier 14 connected to the source and destination. That is, the first table 30 also assigns a correspondence between various bus 12 types and their respective thicknesses. Thus, the minimum required thickness of the bus 12 corresponds to the connection source, connection destination, and bus 12. This correspondence is performed in advance before the selection of the bus 12.

[0053] For example, Figure 4 Both busbars 12C and 12F are 150mm long. However, the thicknesses of busbars 12C and 12F are different. Specifically, busbar 12C has a thickness of 14mm, while busbar 12F has a thickness of 15mm. Therefore, busbar 12C is thinner than busbar 12F. Busbar 12C is a busbar 12 with a minimum thickness sufficient to reliably supply power when an amplifier 14 other than a 300mm wide amplifier 14 is used as the connection destination. On the other hand, busbar 12F is a busbar 12 with a minimum thickness sufficient to reliably supply power when an amplifier 14 with a 300mm wide is used as the connection destination.

[0054] Figure 5 This is a configuration example of the second table 32 stored in the storage unit 24.

[0055] Table 32 is a table that maps the types of the plurality of amplifiers 14 to at least one of the width and rated current of the amplifier 14. In this embodiment, Table 32, as an example, maps the types of the plurality of amplifiers 14 to both the width and rated current of the amplifier 14 (see reference). Figure 5 ). Reference Figure 5 Table 32, for example, shows that amplifier 14A has a width of 60 mm and a rated current of 20 A (Amperes). Additionally, amplifier 14C has a width of 150 mm and a rated current of 80 A. Furthermore, Figure 5 The larger the rated current of the multiple amplifiers 14 illustrated, the larger their width.

[0056] The arithmetic unit 26 is, for example, composed of a processor including a CPU (Central Processing Unit) and a GPU (Graphics Processing Unit). The arithmetic unit 26 includes an acquisition unit 34, an arrangement order selection unit 35, an accessory selection unit 36, and a display control unit 38 (see reference). Figure 3 The acquisition unit 34 acquires multiple amplifiers (selected amplifiers) selected for driving multiple pre-specified motors (specified motors) 16. The arrangement order selection unit 35 selects a predetermined configuration order of the multiple selected amplifiers 14 in the width direction. The accessory selection unit 36 ​​selects accessories. The display control unit 38 causes the display unit 20 to display the selection result. The acquisition unit 34, the arrangement order selection unit 35, the accessory selection unit 36, and the display control unit 38 are implemented by the calculation unit 26 executing the selection program 28.

[0057] The acquisition unit 34 acquires a plurality of selected amplifiers 14. The plurality of selected amplifiers 14 are selected, for example, by a known amplifier selection device. The acquisition unit 34 can acquire the plurality of selected amplifiers 14 from this amplifier selection device. Here, "acquiring selected amplifiers 14" includes acquiring information that allows the type of selected amplifier 14 to be determined based on information stored in the storage unit 24. Specifically, the acquisition unit 34 acquires, for example, the name (e.g., "amplifier 14A"), width, or rated current of the selected amplifier 14. Here, the acquisition unit 34 refers to the second table 32 as needed. Thus, the acquisition unit 34 determines the type of the acquired selected amplifier 14. Furthermore, variations will be described in detail later, but the selected amplifier 14 can also be selected by the selection device 10.

[0058] The types of the multiple selected amplifiers 14 are obtained and used as a reference by the arrangement order selection unit 35. The arrangement order selection unit 35 selects a predetermined arrangement order based on the types of the multiple selected amplifiers 14. The predetermined arrangement order is an arrangement order related to the width direction of the multiple selected amplifiers 14. In this regard, the arrangement order selection unit 35 includes an arrangement order calculation unit 40, a total length calculation unit 42, and an arrangement order determination unit 44 (see reference). Figure 3 The arrangement order calculation unit 40 calculates all possible arrangement patterns of the multiple selected amplifiers 14. The total length calculation unit 42 selects (temporarily selects) multiple buses 12 to be used based on all possible arrangement patterns of the multiple selected amplifiers 14. The total length calculation unit 42 calculates the total length of the temporarily selected buses 12 based on all possible arrangement patterns of the multiple selected amplifiers 14. The configuration order determination unit 44 determines the arrangement order with the smallest total length from all possible arrangement patterns of the multiple selected amplifiers 14 as the prescribed configuration order.

[0059] Specific examples illustrate the selection of the prescribed configuration order by the arrangement order selection unit 35. For example, suppose amplifiers 14A, 14C, and 14E are selected as amplifiers 14. In this case, the arrangement order calculation unit 40 calculates all possible arrangement orders for the three types of amplifiers 14. There are a total of six arrangement methods for the three types of amplifiers 14. Therefore, the arrangement order calculation unit 40 calculates these six arrangement orders in this case. In addition, the total length calculation unit 42 temporarily selects the bus 12 to be used for all six arrangement orders. The temporary selection is performed based on the types of each of the selected amplifiers 14 and the types of connection sources and connection destinations stored in the storage unit 24.

[0060] Taking the arrangement of amplifiers 14A, 14C, and 14E along the +W direction as an example, the temporary selection made by the total length calculation unit 42 is explained. Figure 5 Amplifier 14A has a width of 60mm. Amplifier 14C has a width of 150mm. Amplifier 14E has a width of 260mm. The connection source of bus 12A is amplifier 14A. The connection destination of bus 12A is amplifier 14C. In this case, the total length calculation unit 42 temporarily selects bus 12A (number of uses: 2) by referring to the first table 30 of the storage unit 24. Similarly, the connection source of bus 12C is amplifier 14C. The connection destination of bus 12C is amplifier 14E. In this case, the total length calculation unit 42 temporarily selects bus 12C (number of uses: 2) by referring to the first table 30 of the storage unit 24. The total length calculation unit 42 also temporarily selects the other five arrangement orders.

[0061] Next, the calculation of the total length of the busbars 12 performed by the total length calculation unit 42 will be explained. In this explanation, as described above, we will take the case where amplifiers 14A, 14C, and 14E are arranged sequentially in the +W direction as an example. The busbars 12 temporarily selected by the total length calculation unit 42 are, as described above, busbar 12A (length: 60mm) and busbar 12C (length: 150mm). The required quantity of each of busbars 12A and busbar 12C is 2. In this case, the total length calculation unit 42 calculates 420mm (=60mm + 60mm + 150mm + 150mm) as the total length in the listed arrangement order. Similarly, the total length calculation unit 42 also calculates the total length of the busbars 12 for the other 5 arrangement orders.

[0062] The configuration order determination unit 44 refers to the calculation results of the total length calculation unit 42. Therefore, from the six arrangement orders calculated by the arrangement order calculation unit 40, the configuration order determination unit 44 determines the arrangement order with the smallest total length of the busbars 12 used. This determined arrangement order becomes the selection result (prescribed configuration order) of the arrangement order selection unit 35.

[0063] The accessory selection unit 36 ​​selects the type and quantity of accessories to be connected to the plurality of selected amplifiers 14 arranged in a predetermined configuration order. In this embodiment, the accessory selection unit 36 ​​at least selects the type and quantity of busbars 12 used for parallel connection of the plurality of selected amplifiers 14. This selection is performed based on the determined predetermined configuration order and the types of connection sources and connection destinations stored in the storage unit 24. In this case, the accessory selection unit 36 ​​refers to the result of a provisional selection performed by the total length calculation unit 42.

[0064] Figure 6 This is a schematic diagram illustrating the selection result displayed on the display unit 20 by the display control unit 38.

[0065] The display control unit 38 causes the display screen 20a of the display unit 20 to display the prescribed configuration order selected by the arrangement order selection unit 35, and the type and quantity of the busbars 12 selected by the accessory selection unit 36. For example... Figure 6 As shown, the display control unit 38 displays the type of the selected bus 12 on the wiring diagram 46. The wiring diagram 46 shows the wiring configuration when multiple selected amplifiers 14 are connected in parallel using the selected bus 12. In this case, the operator can easily grasp the wiring configuration, which is therefore preferred. However, it is not limited to this; for example, the display control unit 38 may also display a summary table showing the selection results. Furthermore, Figure 6 The user interface on display screen 20a is merely an example. Therefore, the user interface on display screen 20a is not particularly limited in this embodiment.

[0066] In addition, although Figure 6 The diagram is omitted, but more preferably, the display control unit 38 also displays a diagram of the designated motor 16 connected to the selected amplifier 14 and the power supply P in the wiring diagram 46. This allows the operator to visually understand how to wire and connect the amplifier 14 and the motor 16. Furthermore, the designated motor 16, like the selected amplifier 14, is acquired by the acquisition unit 34.

[0067] More preferably, the display control unit 38 also causes the display unit 20 to display detailed specifications (e.g., rated current) of a plurality of selected amplifiers 14. More preferably, the display control unit 38 also displays detailed specifications (e.g., rated current and rated torque) of a designated motor 16 on the display unit 20. Detailed specifications may also be displayed only for the selected amplifiers 14 and designated motors 16 displayed on the display unit 20 as specified by the operator via the operation unit 22. Thus, the operator can easily confirm the detailed specifications of each of the selected amplifiers 14 and designated motors 16.

[0068] According to the selection device 10 described above, the arrangement order selection unit 35 provided in the selection device 10 automatically and appropriately selects the arrangement order (prescribed arrangement order) of the plurality of selected amplifiers 14 in the width direction. In addition, the selection device 10 of this embodiment also has an accessory selection unit 36. Therefore, the busbar 12 for connecting the plurality of selected amplifiers 14 arranged in the prescribed arrangement order is appropriately selected.

[0069] In this embodiment, the selection device 10 determines the arrangement order that minimizes the total length of the busbars 12 used in all arrangements of the plurality of selected amplifiers 14. Thus, the selection device 10 enables the operator to utilize resources effectively (reducing the use of large busbars 12 and promoting the use of small busbars 12).

[0070] The above is a configuration example of the selection device 10 in this embodiment. Next, the selection method performed by the selection device 10 will be described.

[0071] Figure 7 This is a flowchart illustrating the process of selecting a method for implementing an example.

[0072] Figure 7 The selection method is a method for appropriately selecting the arrangement order of the multiple amplifiers 14. Figure 7 The selection method includes storage step S1, retrieval step S2, sorting order selection step S3, attachment selection step S4, and display step S5.

[0073] In storage step S1, storage unit 24 stores various amplifiers 14. Here, storage unit 24 stores the type of connection source (amplifier 14) and the type of connection destination (amplifier 14) for each of the various buses 12. The various buses 12 are at least different in length. Furthermore, storage step S1 can also be completed before the selected device 10 leaves the factory. In this case, the operator does not need to repeat storage step S1.

[0074] In the acquisition step S2, the acquisition unit 34 acquires a plurality of selected amplifiers 14. Each of the plurality of selected amplifiers 14 is an amplifier 14 selected to drive a pre-specified motor 16.

[0075] In the arrangement order selection step S3, the arrangement order selection unit 35 selects the prescribed configuration order. Figure 7 The arrangement order selection step S3 includes the arrangement order calculation step S31, the total length calculation step S32, and the configuration order determination step S33.

[0076] In the arrangement order calculation step S31, the arrangement order calculation unit 40 calculates all patterns of the arrangement order of the plurality of selected amplifiers 14.

[0077] In the total length calculation step S32, the total length calculation unit 42 calculates the total length of the multiple buses 12 used for all possible arrangements of the multiple selected amplifiers 14. Here, the total length calculation unit 42 temporarily selects the type and number of buses 12 used according to the arrangement of the multiple selected amplifiers 14.

[0078] In the configuration order determination step S33, the configuration order determination unit 44 determines the arrangement order of the plurality of selected amplifiers 14 with the smallest total length as the prescribed configuration order. Here, the configuration order determination unit 44 appropriately refers to the total length calculated according to the arrangement order of the plurality of selected amplifiers 14.

[0079] In the accessory selection step S4, the accessory selection unit 36 ​​selects the type and quantity of accessories connected to the plurality of selected amplifiers 14. Furthermore, in the total length calculation step S32, the type and quantity of busbars 12 used when the plurality of selected amplifiers 14 are arranged in a predetermined order have already been determined. Therefore, the accessory selection unit 36 ​​may also appropriately refer to the results of a temporary selection performed according to the predetermined configuration order.

[0080] In display step S5, display control unit 38 causes display unit 20 to display the prescribed configuration order. In this example, accessory selection step S4 is performed before display step S5. Therefore, display control unit 38 can also display on display unit 20 the types of accessories selected by accessory selection unit 36 ​​and the quantity of each accessory used.

[0081] The above is a configuration example of the selection method of this embodiment. As described above, according to this embodiment, a selection device 10 and a selection method for appropriately selecting the arrangement order of a plurality of amplifiers 14 are provided.

[0082] [Variation Example]

[0083] The above description illustrates an embodiment of the present invention. Various modifications or improvements can be made to the above embodiment. Furthermore, as will be apparent from the description of the technical solution, such modifications or improvements can be included within the technical scope of the present invention.

[0084] The following are several specific examples illustrating variations of the implementation method. However, in the following description, details that are repeated in the implementation method will be omitted as much as possible. In addition, the reference symbols marked on the elements described in the implementation method will be used from the implementation method unless otherwise specified.

[0085] (Variation Example 1)

[0086] The operator can also change the selected configuration order. That is, the selection device 10 causes the display unit 20 to display the selection result. Afterwards, the selection device 10 can also accept operations from the operator to change the specified configuration order.

[0087] The attachment selection unit 36 ​​reselects the type and quantity of busbars 12 according to the revised specified configuration order. Furthermore, the display control unit 38 causes the display unit 20 to display the revised specified configuration order, the reselected type of busbar 12, and the quantity of that busbar 12. According to this modified example, operator convenience is achieved.

[0088] (Variation Example 2)

[0089] The criterion for determining the prescribed configuration order in the implementation is that the total length of the busbars 12 used is minimized. However, the criterion for determining the prescribed configuration order is not limited to this. For example, the selection device 10 may also determine the prescribed configuration order by arranging the multiple selected amplifiers 14 in order of their rated current. Hereinafter, a variation of the selection device 10 based on the above description will be described.

[0090] In addition, in the following description, in order to distinguish it from the implementation method, the arrangement order selection unit 35 is also referred to as "arrangement order selection unit 35A". For the same reason, the attachment selection unit 36 ​​is also referred to as "attachment selection unit 36A".

[0091] Figure 8 This is a schematic diagram of the selected device 10 in Modified Example 2.

[0092] The arrangement order selection unit 35A selects a predetermined configuration order for the plurality of selected amplifiers 14 arranged in order of their rated current magnitude. The rated current of each of the plurality of amplifiers 14 is stored in the storage unit 24. Therefore, the arrangement order selection unit 35A selects the predetermined configuration order by appropriately referring to the storage unit 24. For example, the plurality of selected amplifiers 14 includes amplifier 14A, amplifier 14C, and amplifier 14E. The rated current of each of the plurality of selected amplifiers 14 is stored in the storage unit 24 (refer to...). Figure 5 Amplifier 14A has a rated current of 20A. Amplifier 14C has a rated current of 80A. Amplifier 14E has a rated current of 150A. In this case, the arrangement sequence selection unit 35A determines the arrangement order of amplifiers 14E, amplifier 14C, and amplifier 14A along the +W direction as a prescribed configuration order.

[0093] The prescribed configuration order selected by the arrangement order selection unit 35A is provided for reference by the accessory selection unit 36A. The accessory selection unit 36A selects the type and quantity of accessories connected to the plurality of selected amplifiers 14 according to the prescribed configuration order. For example, the accessory selection unit 36A selects the type and quantity of busbar 12 according to the prescribed configuration order, the type of connection source, and the type of connection destination.

[0094] According to this modified example, the operator can easily obtain the prescribed configuration order of the multiple selected amplifiers 14, the type of bus 12 used, and the number of such bus 12. Furthermore, amplifiers 14 tend to have a wider width as their rated current increases (see embodiment). Therefore, the configuration order determination unit 44 can also determine the prescribed configuration order of the multiple selected amplifiers 14 arranged in width order.

[0095] Figure 9A This is a schematic diagram illustrating a plurality of amplifiers 14 arranged in order of magnitude independent of their rated current and a bus 12 connecting the plurality of amplifiers 14.

[0096] In this modified example, the selected device 10 can easily accommodate a thin busbar 12 (a small busbar 12). Hereinafter, refer to... Figure 9A and Figure 9B Please provide a detailed explanation of the situation.

[0097] Figure 9A An amplifier 14F and two amplifiers 14C are illustrated. Amplifier 14F has a rated current of 200A and a width of 300mm. Amplifier 14C has a rated current of 80A and a width of 150mm. Amplifiers 14C, 14F, and 14C are arranged sequentially along the +W direction (see...). Figure 9AThe multiple busbars 12 selected according to this arrangement order include busbar 12F and busbar 12G (see reference). Figure 9A Bus 12F is used to connect amplifier 14C, which is configured in the -W direction, and amplifier 14F, which is configured in the center. Bus 12G is used to connect amplifier 14F, which is configured in the center, and amplifier 14C, which is configured in the +W direction. Both bus 12F and bus 12G have a thickness (15mm) suitable for connection with amplifier 14, which is 300mm wide.

[0098] Figure 9B This is an example arranged in order of rated current magnitude. Figure 9A A schematic diagram of multiple amplifiers 14 and busbars 12 connecting the multiple amplifiers 14.

[0099] Next, according to Figure 9A The example illustrates the case where one amplifier 14F and two amplifiers 14C are arranged in order of their rated current magnitudes. In this case, amplifiers 14F, 14C, and 14C are arranged sequentially along the +W direction (see [reference]). Figure 9B In this case, the accessory selection unit 36A selects busbar 12G and busbar 12C according to the first table 30. That is, as previously described... Figure 9A The examples are different, in Figure 9B In this example, buses 12F and 12G are not selected. Bus 12C is thinner than bus 12G. Therefore, if the specified configuration order is set to the order of rated current magnitude, it is easy to reduce the required number of thicker buses 12. Bus 12G connects amplifier 14F, configured in the -W direction, and amplifier 14C, configured in the center. Bus 12C connects amplifier 14C, configured in the center, and amplifier 14C, configured in the +W direction.

[0100] Additionally, the selected amplifiers 14 include converters and inverters. Generally, the rated current (capacity) of the converter must be greater than or equal to the rated current of the inverter. When multiple inverters are connected to the converter, the rated current of the converter needs to be greater than or equal to the sum of the rated currents of the multiple inverters. Therefore, in this modified example, the converter and inverter are arranged sequentially along the +W direction.

[0101] (Variation Example 3)

[0102] The selection device 10 can also select multiple designated motors 16 and multiple designated amplifiers 14. Hereinafter, the selection device 10, which is capable of selecting multiple designated motors 16 and multiple designated amplifiers 14, will be described.

[0103] In addition, in the following description, storage unit 24 will be referred to as "storage unit 24C".

[0104] Figure 10 This is a schematic diagram of the selected device 10 in Modified Example 3.

[0105] Storage unit 24C also stores a third table 54 (see reference). Figure 10 Table 54 is a table that corresponds the performance of each of the plurality of motors 16 to the types of amplifiers 14 capable of driving the motors 16. Furthermore, the selection device 10 of this modified example also includes a motor selection unit 56 and an amplifier selection unit 58. The motor selection unit 56 selects a plurality of designated motors 16. The amplifier selection unit 58 selects a plurality of selected amplifiers 14 for driving the plurality of designated motors 16. The plurality of designated motors 16 are driven by the plurality of selected amplifiers 14.

[0106] Figure 11 This is a construction example of Table 54 in the third table.

[0107] The performance characteristics of motor 16 include, for example, its rated current. Table 54 (third table) stores the rated currents of various motors 16A to 16F. For example, the rated current of motor 16A is 20A (see reference). Figure 11 However, the performance of motor 16 is not limited to the rated current. The performance of motor 16 can be, for example, the rated torque of motor 16, the maximum torque of motor 16, or the maximum speed of motor 16.

[0108] The amplifier 14 capable of driving the motor 16 is determined according to Table 32. For example, the rated current of amplifier 14A is 20A (refer to Table 32). Figure 5 Therefore, the motor 16A with a rated current of 20A can be driven by the amplifier 14A.

[0109] The operator specifies the performance of the motor 16 and the required quantity of the motor 16 via the operation unit 22. The motor selection unit 56 selects the type of motor 16 based on the specified performance. For example, the operator specifies "rated current: 20A" as the performance of the motor 16. In this case, the motor selection unit 56 selects motor 16A based on the third table 54. In this case, the motor 16A selected by the motor selection unit 56 is the designated motor 16. Alternatively, the operator may specify the required quantity of motor 16 as "2". In this case, the motor selection unit 56 selects two motors 16A.

[0110] The amplifier selection unit 58 selects an amplifier 14 based on the rated current of the designated motor 16. The amplifier selection unit 58 selects an amplifier 14 for each of the plurality of designated motors 16. Here, the amplifier selection unit 58 appropriately refers to the second table 32. Thus, amplifiers 14 corresponding to each of the plurality of designated motors 16 are selected. For example, the motor selection unit 56 selects motor 16A. In this case, the amplifier selection unit 58 selects amplifier 14A. The amplifier 14 selected by the amplifier selection unit 58 is the selected amplifier 14. The type of selected amplifier 14 is obtained by the acquisition unit 34.

[0111] According to this variation, a selection device 10 is provided for selecting a plurality of designated motors 16 and a plurality of selected amplifiers 14. The selection device 10 selects a bus 12 based on the selection results of the selection of the plurality of designated motors 16 and the selection of the plurality of selected amplifiers 14.

[0112] (Variation Example 4)

[0113] The selection device 10 can also be configured such that, in the wiring connection between the motor 16 and the amplifier 14, a desired accessory can be selected in addition to the bus 12. The following describes the selection device 10 capable of selecting accessories other than the bus 12.

[0114] The following examples illustrate some accessories besides busbar 12. These include, for example, circuit breakers, electromagnetic contactors, fuses, noise filters, motor cables, amplifier cables, power transformers, and surge protectors. These accessories are included in the wiring configuration along with motor 16, amplifier 14, and busbar 12. Accessories can be distinguished by the type of motor 16 or amplifier 14. For example, a motor cable is a cable connected to motor 16. Motor cables can be used independently of amplifier 14. Conversely, an amplifier cable is a cable connected to amplifier 14. Amplifier cables can be used independently of motor 16. However, sometimes the same type of accessory has multiple types. For example, amplifier cables may have types for amplifier 14 with a rated current of 20A and types for amplifier 14 with a rated current of 40A. For other accessories, the corresponding amplifier 14 or the corresponding motor 16 can be predetermined.

[0115] The correspondence between the types of accessories, motors 16, and amplifiers 14 is stored in the storage unit 24. In this case, the accessory selection unit 36 ​​selects the accessory corresponding to each of the multiple designated motors 16 by appropriately referring to the storage unit 24. Additionally, the accessory selection unit 36 ​​selects the accessory corresponding to each of the multiple selected amplifiers 14 by appropriately referring to the storage unit 24. The selected accessories are included in the selection results displayed on the display unit 20. This provides further convenience for the operator.

[0116] Figure 12A This is a construction example of Table 54 in the third table of Variation Example 4. Figure 12B This is a construction example of Table 62 in Variation Example 4.

[0117] The following is for reference Figure 12A and Figure 12B A specific example illustrating this variation is provided. Figure 12A Table 54, the third example of this modification, is illustrated below. Table 54 also corresponds each of the multiple motors 16 to the cable diameter (AWG specification) of the motor cables that can be used with the motors 16. Furthermore, in... Figure 12B Table 62 of this variation is illustrated below. Table 62 maps multiple motor cables to their respective cable diameters (AWG specifications).

[0118] Here, we take the case of multiple specified motors 16, including motor 16A, as an example. The motor cable that can be used for motor 16A is a motor cable with a cable diameter of AWG14 (see reference). Figure 12A A motor cable with a diameter of AWG14 is motor cable A (refer to...). Figure 12B In this case, the accessory selection unit 36 ​​selects motor cable A. Additionally, the display control unit 38 displays motor cable A on the display unit 20. Thus, the operator knows that motor cable A can be used.

[0119] (Variation Example 5)

[0120] This modification will be explained in conjunction with Modification 4. The storage unit 24 may also store the prices of various accessories. For example, the various types of motor cables may include those with the same cable diameter but different prices. In this case, the accessory selection unit 36 ​​refers to the prices of each motor cable. Thus, the accessory selection unit 36 ​​can select the motor cable with the lower price. As a result, the selection device 10 contributes to reducing the operator's accessory procurement costs.

[0121] (Variation Example 6)

[0122] Figure 13 This is a schematic diagram of the selected device 10 in Modified Example 6.

[0123] Selected device 10 may also include an external output unit 60 (see...) Figure 13The external output unit 60 generates electronic order data for the manufacturer. The order lists multiple selected amplifiers 14, multiple specified motors 16, and one or more selected accessories specified by the operator. The operator specifies the products listed on the order via the operation unit 22. Furthermore, the external output unit 60 outputs the order externally. Thus, the operator can easily order the missing accessories from the manufacturer, for example, if necessary. The external output unit 60, for example, instructs a printing press to print the order. Thus, the operator easily obtains a paper-based order. Additionally, the electronic order data can also be attached to an email sent to the manufacturer.

[0124] (Variation Example 7)

[0125] The above variations can also be appropriately combined within the scope of not contradicting each other.

[0126] [Invention obtained from implementation methods]

[0127] The invention that can be mastered based on the above-described embodiments and variations is described below.

[0128] <First Invention>

[0129] A selection device (10) for selecting a predetermined configuration order of multiple amplifiers (14) comprises: a storage unit (24) that stores multiple amplifiers in advance; a retrieval unit (34) that retrieves multiple selected amplifiers selected for driving multiple predetermined motors (16) in advance; an arrangement order selection unit (35) that selects a predetermined configuration order in which the multiple selected amplifiers are arranged adjacent to each other in the width direction according to the types of the multiple selected amplifiers; and a display control unit (38) that causes a display unit (20) to display the predetermined configuration order.

[0130] Therefore, a selection device is provided for appropriately selecting the arrangement order of multiple amplifiers.

[0131] Alternatively, the storage unit stores the types of multiple amplifiers corresponding to the width or rated current of the amplifiers, and the arrangement order selection unit determines the arrangement order of the multiple selected amplifiers according to the width or rated current of the amplifiers stored in the storage unit as the prescribed configuration order. This makes it easy to reduce the required number of thick busbars (12).

[0132] Alternatively, the first invention may also include an accessory selection unit (36) that selects the types and quantities of accessories connected to the plurality of selected amplifiers. The storage unit also stores the plurality of amplifiers and the plurality of accessories that can be connected to the amplifiers. The accessory selection unit selects the types and quantities of accessories connected to the plurality of selected amplifiers according to the prescribed configuration order and the types of the plurality of selected amplifiers. Thus, not only the prescribed configuration order of the amplifiers is selected, but also the accessories are selected.

[0133] Alternatively, one of the various accessories may be a bus (12) connecting multiple amplifiers. The storage unit stores multiple buses of at least different thicknesses, each corresponding to a type of amplifier at the connection source and connection destination. The accessory selection unit selects the type and quantity of the bus based on the type of amplifier at the connection source and connection destination, in a manner that makes the width of the bus as fine as possible. This allows for a significant reduction in the required number of thicker buses.

[0134] Alternatively, the first invention may also include an accessory selection unit (36) that selects the type and quantity of accessories connected to a plurality of selected amplifiers arranged in the prescribed configuration order. The storage unit also stores a plurality of amplifiers and a plurality of accessories that can be connected to the amplifiers. The accessory selection unit selects the type and quantity of accessories connected to the plurality of selected amplifiers based on the types of the plurality of selected amplifiers. Thus, not only is the prescribed configuration order of the amplifiers selected, but the accessories are also selected.

[0135] Alternatively, one of the multiple types of accessories may be a busbar (12) connecting multiple amplifiers. The storage unit stores multiple types of buses of at least different lengths, corresponding to the types of amplifiers at the connection source and connection destination. The arrangement order selection unit includes: an arrangement order calculation unit (40) that calculates all arrangement orders of the multiple selected amplifiers in adjacent configuration; a total length calculation unit (42) that, based on the types of amplifiers at the connection source and connection destination stored in the storage unit, temporarily selects the type and quantity of the busbars used in each of all the arrangement orders, thereby calculating the total length of the multiple busbars used; and a configuration order determination unit (44) that determines the arrangement order with the smallest total length among all the arrangement orders as the predetermined configuration order, wherein the accessory selection unit selects the type and quantity of the busbars according to the predetermined configuration order. This allows for a convenient reduction in the required number of long buses.

[0136] Alternatively, the accessory selection unit may select at least one of the following accessories: circuit breaker, electromagnetic contactor, fuse, noise filter, motor cable, amplifier cable, power transformer, and surge protector. This provides convenience for the operator.

[0137] Alternatively, it may also include an input unit (22) for the operator to change the prescribed configuration order, and the accessory selection unit selects the type and quantity of the accessory according to the changed prescribed configuration order when the operator changes the prescribed configuration order. This provides convenience for the operator.

[0138] Alternatively, the display control unit may cause the display unit to display a wiring diagram (46) showing the wiring configuration of one or more selected accessories and multiple selected amplifiers, as well as the type of the selected accessories. This allows the operator to easily grasp the wiring configuration.

[0139] Alternatively, the storage unit stores multiple motors (16) respectively, corresponding to the performance of the motors and the types of amplifiers capable of driving the motors. The selection device includes: a motor selection unit that selects multiple designated motors from the multiple motors stored in the storage unit based on the performance of the motors specified by the operator and the required number of motors; and an amplifier selection unit that selects multiple selected amplifiers for driving the multiple designated motors selected by the motor selection unit based on the correspondence between the types of motors and amplifiers stored in the storage unit, wherein the acquisition unit acquires the multiple selected amplifiers selected by the amplifier selection unit. Thus, a selection device is provided that not only selects the bus, but also selects multiple designated motors and multiple selected amplifiers before the selection.

[0140] Alternatively, it may also include an external output unit (60) that outputs the selected amplifiers, the designated motors, and the products selected by the accessory selection unit, as ordered by the operator, in the form of an order to the manufacturer. Thus, in cases where, for example, the selected busbars or accessories (see Variation 4) are insufficient, the operator can easily order the missing products from the manufacturer.

[0141] Alternatively, the display control unit may also display detailed specifications of multiple selected amplifiers and multiple designated motors. This allows the operator to easily confirm the detailed specifications of each selected amplifier and designated motor.

[0142] <Second Invention>

[0143] A method for selecting a predetermined configuration order of multiple amplifiers (14) includes: a storage step (S1) of storing multiple amplifiers (14); a retrieval step (S2) of retrieving multiple selected amplifiers (14) selected for driving multiple predetermined motors (16) pre-specified; an arrangement order selection step (S3) of selecting a predetermined configuration order in which the multiple selected amplifiers are arranged adjacently in the width direction according to the types of the multiple selected amplifiers stored in the storage step; and a display step (S5). The predetermined configuration order is displayed on a display unit (20).

[0144] This provides a method for selecting the appropriate arrangement order of multiple amplifiers.

[0145] Alternatively, in the storage step, the types of multiple amplifiers are stored in relation to their widths or rated currents. In the arrangement order selection step, based on the amplifier widths or rated currents stored in the storage step, the arrangement order of the multiple selected amplifiers according to the magnitude of their widths or rated currents is determined as the prescribed configuration order. This easily reduces the required number of thick busbars.

[0146] Alternatively, it may also include an accessory selection step (S4), selecting the type and quantity of accessories connected to the plurality of selected amplifiers arranged in the prescribed configuration order. One of the plurality of accessories is a bus (12) connecting the plurality of amplifiers. In the storage step, the plurality of buses of at least different lengths are stored in correspondence with the types of amplifiers at the connection source and connection destination, respectively. The arrangement order selection step includes: an arrangement order calculation step (S31), calculating all arrangement orders of the plurality of selected amplifiers in adjacent configuration; a total length calculation step (S32), temporarily selecting the type and quantity of the bus used in each of the plurality of arrangement orders based on the types of amplifiers at the connection source and connection destination stored in the storage step, thereby calculating the total length of the plurality of buses used; and a configuration order determination step (S33), determining the arrangement order with the smallest total length among all the arrangement orders as the prescribed configuration order. Thus, the required number of long buses can be easily reduced.
