Technical Field

[0001] This invention relates to a selection device, and more particularly to a selection device and method for selecting a motor and an amplifier. Background Technology

[0002] Industry experts have proposed selection devices that select a motor with the performance desired by the operator and an amplifier capable of driving that motor. An example of such a selection device is disclosed in Japanese Patent Application Publication No. 2019-58046. Summary of the Invention

[0003] Some motors and amplifiers have auxiliary functions, primarily fault detection, while others do not. Furthermore, some motors and amplifiers conform to standard specifications, while others do not. However, current selection methods do not base motor and amplifier selection on information related to auxiliary functions and specifications. Moreover, information regarding the auxiliary functions and specifications of the selected motors and amplifiers is not provided to the operator.

[0004] For the reasons mentioned above, selecting an amplifier that can drive a motor with the desired performance, while considering auxiliary functions and specifications, is not an easy task for operators.

[0005] Therefore, the object of the present invention is to provide a selection device and method that makes it easy for operators to select motors and amplifiers while taking into account auxiliary functions and specifications.

[0007] Another aspect of the present invention is a selection device that, when an operator inputs selection information including conditions related to motor performance and auxiliary functions of the motor and amplifier, and functional specification information according to at least one of specifications, the selection device selects the motor and the amplifier based on the selection information. The selection device comprises: a storage unit that stores the performance of each of a plurality of motors, and stores corresponding functional specification information and an amplifier corresponding to the performance of each of the plurality of motors and the plurality of amplifiers; an input unit for the operator to input the selection information; a motor selection unit that selects the motor satisfying the selection information by referring to the storage unit; an amplifier selection unit that selects the amplifier capable of driving the motor satisfying the selection information and which corresponds to the functional specification information by referring to the storage unit; and a display unit that displays the selected motor and the selected amplifier.

[0008] Another aspect of the invention is a selection method for selecting a motor and an amplifier based on selection information including conditions related to the performance of the motor. This selection method includes: a storage step, storing the performance of each of the plurality of motors, and storing functional specification information representing corresponding auxiliary functions and at least one of specifications, as well as the amplifier corresponding to the performance of the motor, for each of the plurality of motors and the plurality of amplifiers; an input step, where an operator inputs the selection information; a motor selection step, selecting an amplifier capable of driving a motor that meets the conditions based on the information stored in the storage step; a functional specification information acquisition step, acquiring the functional specification information corresponding to the selected motor and the selected amplifier based on the information stored in the storage step; and a display step, displaying the selected motor, the selected amplifier, and the acquired functional specification information.

[0015] Figure 6 Here is a flowchart illustrating the selection method of an example implementation. Detailed Implementation

[0016] The following describes a suitable implementation method while referring to the appendix. Figure 1 The selected apparatus and selected method of the present invention will be described in detail below.

[0017] [Implementation Method]

[0018] Figure 1 This is a schematic configuration diagram of the selected device 10 for the implementation method.

[0019] The selection device 10 is an electronic device (computer) provided for easily constructing a servo mechanism (servo system) equipped with a servo motor and a servo amplifier. The selection device 10 of this embodiment includes a display unit 12, an operation unit (input unit) 14, a storage unit 16, and an arithmetic unit 18. These components will be described in sequence below. Furthermore, the term "servo motor" will be abbreviated as "motor" and the term "servo amplifier" will be abbreviated as "amplifier".

[0020] Display unit 12 is a display device that displays information on a screen. The screen of display unit 12 is not limited, and may be, for example, a liquid crystal display. Display unit 12 displays an input screen for inputting selection information, which will be described later, or a selection result.

[0021] The purpose of providing the operation unit 14 is to allow the operator to input information into the selected device 10, such as by using a keyboard, mouse, or a touch panel mounted on the screen of the display unit 12. The operator can input selected information into the selected device 10 by operating the operation unit 14.

[0022] Storage unit 16 stores information. Storage unit 16 is constructed of hardware such as RAM (Random Access Memory) or ROM (Read Only Memory). Storage unit 16 stores the specified selection program 20 and the specified selection table 22.

[0023] Selection Procedure 20 is a procedure that specifies a method for selecting motors and amplifiers (hereinafter referred to as the "Selection Method"), which makes it easier for operators to select an amplifier while considering its auxiliary functions and specifications. Details of the Selection Method are described below.

[0024] Figure 2 Select the composition diagram of Table 22.

[0025] The selection table 22 is a table that specifies the information required to perform the selection method. Here, the selection table 22 in this embodiment includes the first table 24, the second table 26, the third table 28, and the fourth table 30, as described below.

[0026] Table 24 is a table specifying multiple motors and information indicating the performance of each motor. Information indicating motor performance includes, for example, the value of the motor's continuous rated current. However, the information indicating motor performance is not limited to this; it may also include the value of the motor's continuous torque (rated torque), maximum torque, or maximum speed.

[0027] Figure 3A This is a table representing the first constituent example of Table 24.

[0028] Figure 3A The example shown is Table 24, which specifies the value of the continuous rated current as information indicating the performance of the motor. In the structure of this Table 24, motor identification information, indicating the name or management number of each of the multiple motors A to F, is specified in the left column, and the value of the continuous rated current of each motor A to F is specified in the right column. Figure 3A For example, we know that the continuous rated current of motor A and motor B is 20A (amperes), and the continuous rated current of motor C and motor D is 40A.

[0029] Figure 3B This is a table representing the second constituent example of Table 24 in Table 1.

[0030] Regarding the structure of Table 24 in Table 1, it can also be like... Figure 3B As illustrated in the example, a configuration is provided for a single motor, specifying various information to represent its performance. According to... Figure 3B For example, regarding motor C, we know that the continuous rated current is 40A, the continuous torque is 4Nm (Newton-meters), the maximum torque is 15Nm, and the maximum speed is 5000rpm (revolutions per minute).

[0031] Next, Table 26 will be explained. Table 26 is a table that specifies multiple amplifiers and information indicating the performance of the motors that each amplifier can drive in a related manner. For example, Table 1, 24 specifies the value of the continuous rated current as information indicating the performance of the motor. In this case, Table 26 specifies the value of the continuous rated current as information indicating the performance of the motors that can be driven.

[0032] Figure 4 This is a table representing an example of the structure of Table 26.

[0033] Figure 4 The example shown is Table 26, which specifies the value of the continuous rated current as information indicating the performance of the motor that can be driven. In the structure of this Table 26, amplifier identification information indicating the name or management number of each amplifier A to F is specified in the left column, and the value of the continuous rated current corresponding to each amplifier A to F is specified in the right column.

[0034] according to Figure 4 For example, regarding a single-axis amplifier A, it is known that the continuous rated current it can supply is 20A. Furthermore, for example, regarding a multi-axis amplifier B that can simultaneously drive two motors, it is known that the continuous rated current for both axes is 20A.

[0035] Next, Table 3, 28 will be explained. Table 3, 28 is a table that specifies multiple motors and multiple amplifiers and their respective functional specifications.

[0036] Here, we will explain the "functional specification information." Functional specification information refers to the auxiliary functions of the motor and amplifier, as well as information based on at least one of the specifications. Auxiliary functions are optional functions and are a general term for functions designed to facilitate the operation of the amplifier.

[0037] As auxiliary functions, not all will be listed in this embodiment, but representative examples include fault detection, predictive maintenance, power-saving functions, advanced functions, and safety functions. Fault detection can be further subdivided into ground fault current detection, fan motor rotation detection, brake check, and temperature monitoring. Predictive maintenance can be further subdivided into action time monitoring, motor insulation resistance measurement, and electrolytic capacitor capacity check. Furthermore, safety functions can be further subdivided into mechanical braking operation and dual monitoring of electrical signals.

[0038] The advanced functions mentioned in this embodiment are a collective term for functions related to ease of use, motor power enhancement, and environmental impact. If advanced functions are further subdivided, they may include functions such as line-saving support, harmonic outflow current countermeasures, DC link voltage boosting, or frequency setting functions in so-called PWM (Pulse Width Modulation) control.

[0039] Furthermore, the "standards" referred to here are the standards upon which motors and amplifiers are based. These "standards" are internationally recognized or established by each country or region. Representative examples include standards established by the International Electrotechnical Commission (IEC) and Japanese Industrial Standards (JIS standards).

[0040] Figure 5This is a table representing an example of the structure of Table 28, number 3.

[0041] exist Figure 5 In the example of Table 3, 28, the identification information (motor identification information and amplifier identification information) is specified in the left column, and the information indicating auxiliary functions and specifications included in the functional specifications of each motor A to F and each amplifier A to F is specified in the right column. According to Table 3, 28, for example, we know that motor B has a "brake check" auxiliary function, amplifier A has a "motor insulation resistance measurement" auxiliary function, and motor A and amplifier B do not have any auxiliary functions. Furthermore, we know that amplifier A and amplifier B are based on "JIS specifications".

[0042] Next, Table 4, 30 will be explained. Table 4, 30 is a table that specifies functional specification information and accompanying text and diagrams (hereinafter referred to as "notes, etc.") in an associated manner.

[0043] Table 4, 30, like Table 3, 28, has a left and right column. The name of the functional specification information is specified in the left column, and the corresponding notes are specified in the right column. These notes may include brief or detailed explanations of how to use the auxiliary functions represented by the functional specification information, or descriptions of the countries that approved the specifications.

[0044] The above is an example of selecting Table 22. Furthermore, as long as the correspondence between the motor and its performance, the correspondence between the motor's performance and the amplifier, and the correspondence between the motor and amplifier and their functional specifications can be referenced, the configuration of selecting Table 22 is not limited to... Figures 2-5 The structure is illustrated in the example.

[0045] Return to Figure 1 Next, the arithmetic unit 18 will be described. The arithmetic unit 18 processes information through arithmetic operations. The arithmetic unit 18 is composed of hardware such as a CPU (Central Processing Unit) or a GPU (Graphics Processing Unit).

[0046] Furthermore, the arithmetic unit 18 of this embodiment includes a motor selection unit 32, an amplifier selection unit 34, a function specification information acquisition unit 36, and an output unit 38. These units are implemented by the arithmetic unit 18 reading and executing the selection program 20 described above.

[0047] When the operator inputs selection information into the selection device 10 (calculation unit 18) via the operation unit 14, the motor selection unit 32 selects the motor based on the input selection information via the reference storage unit 16.

[0048] Here, we will explain "selected information." Selected information includes at least conditions related to the motor's performance. These performance-related conditions refer to specified values ​​or ranges of values ​​for parameters such as the continuous rated current mentioned earlier.

[0049] The motor selection unit 32 can easily select a motor that meets the selection criteria by referring to the first table 24 in the storage unit 16. Here, if multiple motors that meet the criteria are found, the motor selection unit 32 will select (list) all of the multiple motors that meet the criteria.

[0050] When the operator inputs selection information to the selection device 10 (computation unit 18) via the operation unit 14, the amplifier selection unit 34 selects an amplifier that can drive a motor that meets the conditions of the input selection information via the reference storage unit 16.

[0051] The amplifier selection unit 34 can easily select an amplifier that can drive a motor that meets the selection criteria by referring to Table 26 in the storage unit 16. Here, if multiple amplifiers that can drive a motor that meets the criteria are found, the amplifier selection unit 34 will select (list) all of the found amplifiers.

[0052] When a motor and an amplifier are selected, the functional specification information acquisition unit 36 ​​acquires the functional specification information corresponding to the selected motor and the selected amplifier through the reference storage unit 16.

[0053] The functional specification information acquisition unit 36 ​​can easily acquire functional specification information corresponding to the selected motor and the selected amplifier by referring to Table 28 of the storage unit 16. Here, when multiple motors are selected, the functional specification information acquisition unit 36 ​​acquires functional specification information for each of the multiple selected motors. Similarly, when multiple amplifiers are selected, the functional specification information acquisition unit 36 ​​acquires functional specification information for each of the multiple selected amplifiers. Furthermore, when the selected motor and the selected amplifier correspond to multiple auxiliary functions or specifications, the functional specification information acquisition unit 36 ​​acquires all of the multiple auxiliary functions or specifications corresponding to the selected motor and the selected amplifier. Moreover, when annotations or the like corresponding to the functional specification information can be acquired by referring to Table 30, the functional specification information acquisition unit 36 ​​also acquires those annotations or the like.

[0054] The output unit 38 outputs the motors selected by the motor selection unit 32 (a list of motors), the amplifiers selected by the amplifier selection unit 34 (a list of amplifiers), and the functional specification information and comments obtained by the functional specification information acquisition unit 36 ​​as selection results to the display unit 12.

[0055] 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.

[0056] Figure 6 Here is a flowchart illustrating the selection method of an example implementation.

[0057] As described above, the selection method in this embodiment is a method of selecting a motor and an amplifier capable of driving the motor based on selection information including conditions related to the motor's performance. Figure 6 As illustrated, the selection method includes a storage step (S1), an input step (S2), a motor selection step (S3), an amplifier selection step (S4), a function specification information acquisition step (S5), and a display step (S6).

[0058] The storage step involves storing the performance of each of the multiple motors, and storing the corresponding functional specifications and the amplifier corresponding to the motor performance for each of the multiple motors and multiple amplifiers. Furthermore, the storage step may also store annotations explaining the functional specifications. In this embodiment, this information is stored in the storage unit 16 as information constituting the selection table 22.

[0059] The input step is the step in which the operator inputs selected information. This input is performed on the selection device 10 (computation unit 18) via the operation unit 14. As mentioned above, the selected information contains the conditions specified by the operator for the performance of the motor.

[0060] The following explanation will continue with the example of a scenario where the operator specified "continuous rated current: 20A" as the condition for selecting information.

[0061] The motor selection step is a step of selecting a motor that meets the conditions of the selection information entered in the input step, based on the information stored in the storage step. The motor selection step is performed by the motor selection unit 32. The motor selection unit 32 easily selects the motor by referring to Table 24.

[0062] For example, select the information specified in Table 24 of Table 22, such as Figure 3A In this case, the motor selection unit 32 selects motors A and B that meet the input condition "continuous rated current: 20A".

[0063] The amplifier selection step is a step of selecting an amplifier that can drive a motor that meets the conditions of the selection information input in the input step, based on information stored in the storage step. The amplifier selection step is performed by the amplifier selection unit 34. The amplifier selection unit 34 easily selects the amplifier by referring to Table 26.

[0064] For example, select the information specified in Table 26 of Table 22, such as Figure 4 In this case, the amplifier selection unit 34 selects amplifiers A and B that can drive motors (motor A and motor B) that meet the input condition "continuous rated current: 20A".

[0065] Furthermore, in Figure 6 In the illustrated flowchart, the amplifier selection step begins after the motor selection step, but it can also be performed before or simultaneously with the motor selection step.

[0066] The functional specification information acquisition step is a step of acquiring functional specification information corresponding to the selected motor and the selected amplifier based on the information stored in the storage step. This step is performed by the functional specification information acquisition unit 36. The functional specification information acquisition unit 36 ​​can easily acquire the functional specification information by referring to Table 28 (3rd table).

[0067] For example, select the information specified in Table 28 of Table 22, such as Figure 5 In this case, the functional specification information acquisition unit 36 ​​acquires "Auxiliary function: - (None)" and "Based on specification: JIS specification" for motor A selected in the motor selection step. Similarly, for motor B selected in the motor selection step, it acquires "Auxiliary function: Brake check" and "Based on specification: JIS specification". Furthermore, for amplifier A selected in the amplifier selection step, it acquires "Auxiliary function: Motor insulation resistance measurement function" and "Based on specification: JIS specification". Similarly, for amplifier B selected in the amplifier selection step, it acquires "Auxiliary function: - (None)" and "Based on specification: JIS specification".

[0068] Furthermore, in this step, if the correspondence between functional specification information and annotations explaining the functional specification information is stored in the storage step, and if annotations explaining the obtained functional specification information can be obtained based on the correspondence, then the annotations can be obtained further.

[0069] Furthermore, in this step, if the functional specification information only includes auxiliary functions and one of the specifications, only one of them needs to be obtained.

[0070] Furthermore, this step can also be used when the functional specification information includes both auxiliary functions and specifications, and only one of these two aspects is retrieved. In this case, the operator can pre-select which aspect of auxiliary functions or specifications to retrieve in this step.

[0071] The display step is the step of displaying the motor selected in the motor selection step, the amplifier selected in the amplifier selection step, and the functional specification information and comments obtained in the functional specification information acquisition step. This step is performed by the output unit 38, which displays the selected motor, the selected amplifier, and the acquired functional specification information and comments on the display unit 12.

[0072] By following the displayed steps, operators can easily access information about the motor with the desired performance, the amplifier that can drive the motor, and the functional specifications of both the motor and the amplifier. If multiple motors or amplifiers are displayed, operators can select the appropriate motor and amplifier while referring to the displayed specifications.

[0073] Furthermore, during the display process, if annotations or similar information are obtained during the functional specification information acquisition step, these annotations or similar information are further displayed. This allows operators to easily grasp the information even if they are unfamiliar with how to use the auxiliary functions or the general specifications.

[0074] The above is a configuration example of the selection method performed by the selection device 10 in this embodiment. As described above, according to this embodiment, a selection device 10 and a selection method are provided that are easy for operators to select motors and amplifiers in consideration of auxiliary functions and specifications.

[0075] [Variation Example]

[0076] The embodiments of the present invention have been described above using one example. Various modifications or improvements can be made to the embodiments. Furthermore, as described in the claims, it is evident that such modifications or improvements are included within the scope of the present invention.

[0077] (Variation Example 1)

[0078] The selection information may also include functional specification information. In this case, the motor selection unit 32 can select a motor that meets the selection information, that is, a motor that meets the conditions related to the specified performance and corresponds to the specified functional specification information. Furthermore, the amplifier selection unit 34 can select an amplifier that can drive the motor that meets the selection information and that corresponds to the functional specification information. Thus, the operator can easily obtain the desired auxiliary function and the amplifier corresponding to the specifications as the selection result.

[0079] Furthermore, in this modified example, if the former of the motor's functional specifications information and the amplifier's functional specifications information is not included in the selection information, the motor selection unit 32 can select a motor that meets the performance conditions related to the selection information in the same way as in the embodiment.

[0080] The selected motor, the selected amplifier, the obtained (specified) functional specification information, and comments are displayed on the display unit 12 as in the same manner as in the embodiment. However, in this modified example, the functional specification information is something that the operator should have known at the time it was included in the selection information, so it may not be displayed.
