[0008] A method for commissioning a drive is known from EP 1 929 380 B1.

[0009] A converter product family is known from DE 1989 47 789 A1. Summary of the invention

[0010] It is therefore an object of the present invention to improve a drive system in which commissioning can be performed in a simple manner.

[0011] According to the invention, this object is achieved by a drive system according to the features of claim 1 and a method according to the features of claim 10 .

[0012] In a drive system having an electric motor and an electronic device, an important feature of the invention is that the electronic device has an electronic circuit which feeds the electric motor.

[0013] The electronic device has a module.

[0014] In this case, the electronic device, in particular the electronic circuit, can be connected to a computer, in particular a commissioning PC, for data exchange, in particular for commissioning the drive system.

[0015] The module is inserted into a recess, in particular a notch, of the electronic device.

[0016] Therein, the module has an actuatable switch, in particular a DIP switch, and has a memory for storing the first parameter.

[0017] The advantage here is that simple commissioning can thus be carried out. Either a computer is connected for data transmission, so that the parameters can be entered conveniently on its keyboard or on its touch-sensitive screen following a simple menu-based approach, or it is only necessary to actuate the DIP switches in a simple manner according to the markings on the housing of the module or according to the operating instructions, so that the parameters stored in the module and the parameters coded by the switch position of the DIP switches are supplied to the electronic device and used for commissioning. The module can be simply plugged into the cover of the electronic device, since only the cover is removable, and the module can then be inserted into a recess or notch formed in the cover as a receptacle for the module.

[0018] In an advantageous embodiment, the electronic circuit has an additional memory for storing second parameters, in particular, the second parameters include the first parameters and a parameter corresponding to the switch position of the switch. The advantage here is that the (computer) is superfluous when an additional memory is present, because the parameters required for commissioning are stored in the additional memory. The additional memory is designed to be long-term stable. That is, the storage of the data written into the additional memory is permanent and therefore not affected even in the event of a power failure. If a computer is connected for data transmission, the parameters transmitted by the computer have a higher priority, so that the parameters stored in the additional memory and in the module and the switch position of the DIP switch are not used for commissioning.

[0019] The additional memory can already be parameterized during the manufacture of the electronic device, thus making it possible to avoid model-dependent assignment errors.

[0020] Furthermore, particularly fast data transmission can be carried out since the bandwidth of the data communication channel provided within the electronic device is very high.

[0021] In an advantageous embodiment, the electronic device has a cover, in which a printed circuit board of the electronic circuit is accommodated.

[0022] In this case, data lines, in particular for connecting a computer or the computer to the electronic circuit, are implemented via cable glands of the cover or via cable glands of a connection piece or a terminal box part on which the cover is placed. This has the advantage that the printed circuit board is protectively surrounded by the cover, wherein the cover can be connected thermally to heat-generating components of the electronic circuit and thus heat can be effectively dissipated if the cover has cooling fins on its outer side.

[0023] In an advantageous embodiment, the module has at least one U-shaped clip, on which a latching projection is formed or molded.

[0024] In particular, the latching projection engages from behind an insulating element which, together with the cover element, surrounds the electronic circuit in a housing-forming manner.

[0025] The U-shaped clip can be elastically deflected relative to the housing part of the module.

[0026] In particular, the U-shaped clip is formed or molded integrally on the housing part of the module. This has the advantage that the module can be connected in a clamping manner. To this end, the module only needs to be held at its U-shaped clip, which is pressed against each other to achieve a certain elastic deflection and then clamped by inserting the module into the recess.

[0027] In an advantageous design, a pin is formed on the housing part of the module, which is inserted into a correspondingly elongated / slim hole when the module is inserted into the recess. The advantage here is that a guide is formed when the module is inserted.

[0028] In an advantageous embodiment, the circuit board is equipped with a plug connector which is plug-connected to a mating plug connector arranged in a connection piece or a terminal box part, on which the cover is placed.

[0029] In an advantageous embodiment, the electronic circuit has a selection element which is suitably designed to:

[0030] - when there is a computer connected to the electronic circuit for data exchange, the parameters transmitted by the computer are used for commissioning of the electronic equipment,

[0031] - if the computer is not connected to the electronic circuit for data exchange, the parameters stored in the additional memory of the electronic circuit are used for commissioning the electronic circuit,

[0032] Otherwise, i.e. when neither the computer nor the additional memory is present or when no additional memory is present, the parameters stored in the memory of the module are used for commissioning. Advantageously, the selection element selects the parameters for commissioning according to their priority, wherein the computer has the highest priority, the additional memory has a lower priority and the memory of the module has the lowest priority.

[0033] In the method for commissioning a drive system, important features are,

[0034] - if a computer is connected to the electronic circuit for data exchange, performing commissioning of the electronic device using the parameters stored in the computer,

[0035] - if a further memory of the electronic device is present and contains parameters for commissioning, and if the computer is not connected to the electronic circuit for data exchange, commissioning of the electronic device is performed using the parameters stored in such further memory,

[0036] If no further memory is present or does not contain parameters for commissioning and if a computer is not connected to the electronic circuit for exchanging data, commissioning of the electronic device is performed using the parameters stored in the memory of the module.

[0037] The advantage here is that commissioning can be carried out simply and safely. This is because if a computer is connected, it is used for commissioning, i.e. the parameters are entered on the computer or the parameters of the computer are used. If there is no such commissioning option, the parameters of another memory available in the electronic device are used. If this option is also not possible, the parameters stored in the memory of the module are used together with the information about the switch position of the DIP switch.

[0038] In an advantageous embodiment, the electronic device has a cover, in which a printed circuit board of the electronic circuit is accommodated.

[0039] In this case, data lines, in particular for connecting a computer to an electronic circuit, are implemented via cable glands of the cover.

[0040] The electrical line is led from the cover part to the connection part or the terminal box part via a plug connection.

[0041] In this case, commissioning is carried out with the cover removed, i.e. the plug connection disconnected. This has the advantage that parameterization / determination of parameters is possible with the cover disconnected, and therefore there is no risk that the motor is already started during parameterization and commissioning and the electronic circuit is put into the desired / intended operating state. Although not all components of the electronic circuit can be fully powered, at least a sufficient energy supply for powering the components required for parameterization is transmitted to the computer via the data line.

[0042] Further advantages are derived from the dependent claims. The invention is not limited to the feature combinations of the claims. For a person skilled in the art, further meaningful combinations of the claims and / or individual claim features and / or description features and / or drawing features emerge, in particular from the objectives proposed and / or from a comparison with the prior art. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] The invention will now be explained in detail with the aid of a schematic diagram:

[0044] exist Figure 1 An oblique view of the module 1 is shown in FIG.

[0045] exist Figure 2 2 shows an oblique view of the cover 20 with the module 1 inserted therein. DETAILED DESCRIPTION

[0046] As shown in the figures, a circuit board is received in the cover 20 , on which the plug connector 21 is mounted.

[0047] The cover 20 can therefore be placed on a connector, not shown in the drawings, which has a corresponding mating plug connector that can be plug-connected to the plug connector 21. In this way, an electronic device can be manufactured, in which the connector of the electronic device can be installed power supply lines and data lines, which are electrically connected to the contacts of the mating plug connector, so that the electronic circuit arranged on the circuit board can be powered.

[0048] The data lines are also conducted to the electronic circuit via the plug connection or alternatively via a socket arranged in the housing wall of the cover 20 , the contacts of which are electrically connected to the conductor tracks of the printed circuit board.

[0049] Alternatively, the cover 1 can also be placed on a terminal box part of the motor, which also has the function and design features of a terminal part. The terminal box part is connected to a motor housing part covering the motor stator, in particular, is formed in one piece and / or integrally with the motor housing part.

[0050] Thus, the electric machine may be implemented integrally with the electronic circuit.

[0051] In particular, the electronic circuit has an inverter which feeds a motor or the motor. Thus, a regulated operation of the motor can be implemented, either as a motor with a converter when the cover is placed on the terminal box part, or alternatively as a motor with a removed converter arranged in the installation / system, i.e. arranged on site, which supplies the motor with power.

[0052] The module 1 is plug-connected on the bottom side, ie the side that acts as the inside after the cover 20 has been put on.

[0053] For this purpose, the insulating part 22 has a recess, which essentially covers the printed circuit board and is connected to the cover on the side of the printed circuit board facing the plug connector 21 .

[0054] Furthermore, the insulating part 22 has a further recess for the plug connector 21 .

[0055] The module 1 has a memory in which parameters for adjusting the electronic circuit are stored. In addition, the module 1 has switches 2, in particular DIP switches. The switches can be used to set parameters, such as the connection type of the motor fed by the electronic circuit, wherein a star connection or a delta connection can be coded as the connection type by means of one or more DIP switches. For example, the motor protection class, in particular the type of sensor for monitoring the motor temperature, in particular, for example, a temperature sensor, a thermistor, a positive temperature coefficient resistor or a PK1000 can be set by means of one or more switches.

[0056] The module 1 also has a U-shaped clip, in particular a spring U-shaped clip 3, which is fastened and / or molded on the housing part of the module 1 and can be elastically deflected relative to the housing part of the module 1. The U-shaped clip has a latching projection on its side facing away from the module housing part, so that when the module 1 is inserted into the recess of the module 1, the latching projection engages behind the insulating part 22. In this way, latching can be achieved.

[0057] In addition, the module 1 has another U-clip on the side of the module 1 facing away from the U-clip 3, which can also be elastically deflected relative to the housing part and has oppositely directed locking protrusions, so that the module 1 can be locked in two when inserted into the recess of the cover 20.

[0058] The module 1 can therefore be clipped into the cover 20 .

[0059] Pins 4 are integrally formed on the module 1 , which, when the module 1 is inserted into the recess, also engage in correspondingly elongated holes, so that the module 1 can be inserted into the cover 20 in a guided manner until a clipping occurs.

[0060] The U-shaped clip 3 has, at its end region facing away from the pin 4 , grooves which are regularly spaced apart from one another and which extend transversely to the plug-in direction of the module 1 .

[0061] In order to facilitate the removal of the module 1 from the cover 20, the corresponding latching projection is arranged approximately in the middle of the corresponding U-shaped clip 3, and the corresponding end region of the corresponding U-shaped clip 3 is widened and has a grooved surface. This achieves improved grip and leverage, i.e., the U-shaped clip 3 can be elastically pressed against the housing part, i.e., the base body, of the module 1 with little effort, so that the clip connection can be released.

[0062] When commissioning a drive system, ie an electric machine fed by an electronic circuit, the electronic circuit, in particular a control device contained in the electronic circuit, for carrying out a controlled operation of the electric machine requires parameters.

[0063] If the electronic circuit is connected by means of a data line to a computer arranged outside the cover 1 , the parameters can be transferred from the computer by means of suitable software, ie the electronic circuit can be parameterized by the computer.

[0064] However, if no such computer is connected to the electronic circuit, a check is performed to determine whether a memory containing the parameters is present in the electronic circuit. If a memory is present, the memory is used for parameterization.

[0065] However, if such a memory and such a computer are not present, parameterization is performed by reading out the parameters stored on the module 1 and set via the DIP switches 2 .

[0066] Preferably, the electrical line is led from the cover part to the connection part or the junction box part via a plug-in connection part, thereby simplifying maintenance.

[0067] In other embodiments according to the invention, a housing part is used as a base body, on which the pin 4 and the U-shaped clip 3 including the latching projection are formed in one piece, ie integrally.
