Definitions
- Drive unit for at least one electric motor and cooperating with the drive unit drive control
- the present invention relates to a drive device for at least one electric motor, which is operated as follows:
- the drive unit determines current setpoint values for the electric motor based on a sequence of setpoints and corresponding actual values for the electric motor.
- the setpoints are made available to the drive unit by a higher-level drive control via a communication connection.
- the drive unit either provides the current setpoint values to a drive unit for the electric motor or determines drive signals for a number of circuit breakers based on the current setpoint values and corresponding actual current values and outputs the drive signals to the circuit breakers.
- the electric motor is turned on according to the respective current setpoint to a power supply.
- the drive unit decides on the basis of the drive unit externally supplied first signals, whether it monitors an actual value of the electric motor to maintain an actual value condition (monitoring operation).
- the drive unit automatically triggers the electric motor to be disconnected from the power supply if the actual value does not comply with the actual value condition.
- the present invention further relates to a computer program comprising machine code, the execution of which by a drive device for at least one electric motor causes the drive device to be operated as described above.
- the present invention also relates to a data carrier on which such a computer program is stored.
- the present invention also relates to a drive control operated as follows:
- the drive controller determines, based on an application program and / or on the basis of inputs from a user for at least a first electric motor, a first sequence of desired values.
- the drive controller provides at least the first sequence of setpoints via a communication link to a first subordinate drive unit available.
- the drive control checks whether the first drive unit monitors an actual value of the first electric motor to maintain an actual value condition.
- the drive controller determines the first sequence of setpoint values taking into account the actual value condition.
- the present invention further relates to a computer program comprising machine code whose execution by a drive control for at least one first electric motor causes the drive control to be operated as described above.
- the present invention also relates to a data carrier on which such a computer program is stored.
- the drive controls are generally designed as motion control devices, in particular as numerical controls for machine tools or as motion controls for production machines.
- the consequences of setpoints transmitted by the drive controllers to the corresponding drive units are usually consequences of position or speed setpoints. In individual cases, however, the determination of torque or other setpoints is possible.
- the drive units are common engine control units. At least they convert the transmitted position, speed, torque or other setpoints into current setpoints. In some cases, the drive units themselves directly control their electric motors. In other cases, they transmit the current setpoint values to a subordinate device, which causes the determination of the control signals for circuit breakers and the activation of the power switches.
- the drive unit In normal operation, the drive unit only carries out the conversion of the transmitted sequence of setpoint values into the current setpoint values, but does not carry out any monitoring tasks with respect to the electric motor. In some operating conditions, however, the electric motor must be controlled in a certain way and also monitored. For example, depending on the operating situation, one of the following requirements may be met:
- the electric motor should be decelerated to zero speed and then actively kept at standstill.
- the speed of the electric motor should be lowered until it is below a maximum allowable speed.
- the motor should only be operated in a certain direction of rotation. This mode of operation may be particularly important if there is a danger of a so-called pull-through load.
- the motor should be operated with a maximum torque limit.
- the electric motor should be brought to a standstill and then switched off.
- a cooperation with a mechanical brake can take place.
- Such monitoring is usually done by the drive unit. If the electric motor does not comply with the required operating conditions during monitoring operation of the drive unit, it will be disconnected from the drive unit by the power supply unit. separately.
- a braking device in particular a mechanical brake, are operated.
- the drive unit decides on the basis of corresponding safety-related signals, which are supplied to the drive unit from the outside.
- Parameters which define the state to be monitored in more detail can also be fed to the drive unit from the outside. For example, the maximum permissible speed value, the desired direction of rotation or the maximum permissible torque value can be supplied to the drive unit.
- the electric motor may continue to be powered up even after the monitoring operation has been initiated.
- only such states are important.
- the electric motor remains connected to the power supply and is operated in accordance with the current setpoint values determined by the drive unit. Only if the electric motor violates the actual value condition does the drive unit automatically cause the electric motor to be disconnected from the power supply.
- the drive unit pulls - figuratively speaking - the emergency brake.
- the drive control is usually a guide of the electric motor.
- the chronological sequence of desired values is thus determined by the drive control, taking into account the dynamics of the electric motor-possibly also taking into account a load actuated by the electric motor-such that the electric motor can follow the corresponding setpoint specification. Therefore, when the monitoring operation is triggered, the corresponding information usually does not need only the Drive unit to be supplied, but also the drive control.
- Various approaches are known in the art for this purpose.
- the first signals from the fail-safe programmable logic controller are transmitted not only to the drive unit but also to the drive control.
- the drive control passively monitors the data traffic from the fail-safe programmable logic controller to the drive unit.
- the drive unit outputs the first signals and that the first signals are fed directly to the drive control via a separate terminal module. This feeding must be done in addition to the supply of the first signals to the drive unit.
- the first signals directly to the drive unit via a terminal module.
- the drive control it is known to associate the drive control with its own terminal module.
- the signals supplied to the drive control can alternatively be directly the first signals or signals to be output by the drive unit based on the first signals.
- the object of the present invention is to provide a further possibility by means of which the information relevant for the monitoring operation (monitoring mode yes or no and actual value condition to be monitored) can be made known in a simple manner and reliably to the drive control.
- the object is achieved by means of a device with the features of claim 1 and a drive control with the features of claim 12.
- the drive device of the drive control via the same communication link, via which the drive unit from the higher-level drive control the sequence of setpoints is provided, a first information available, indicating whether the drive unit is in monitoring mode. At least in
- Monitoring operation provides the drive unit of the drive control via the same communication link a second information available, which shows what the actual value condition consists.
- the sequence of setpoints is often a consequence of position or speed setpoints.
- the actual value condition is in many cases the maintenance of a limit speed by the electric motor and / or the rotation of the electric motor in a desired direction of rotation.
- the drive control determined based on the application program or the inputs of the user for at least a second electric motor, a second sequence of setpoints.
- the second sequence of setpoints is often of the same type as the first set of setpoints.
- both the first sequence of setpoints and the second sequence of setpoints are speed setpoints.
- the drive controller provides the second sequence of desired values either to the first drive unit (if this can also drive the second electric motor) or to a second drive unit.
- the drive controller determines the consequences of setpoint values in a coordinated manner. This coordination is in particular made regardless of whether the first drive unit is in monitoring mode or not. According to the invention, therefore, in the case where the first drive unit monitors the first electric motor for compliance with the actual value condition, the drive control also determines the second series of set values, taking into account the actual value condition, which actually only applies to the first electric motor.
- the actual value condition is time-variable and / or can be parameterized on the basis of second signals supplied from the outside by the drive unit.
- the drive unit can be supplied externally, which value should have the maximum permissible speed.
- the feeding of this value can be done for example by means of a user input.
- the time profile of the actual value condition can be determined, for example, be it on the basis of external inputs, be it on the basis of internal parameterizations, in particular taking into account the actual values given at the time of the change to the monitoring mode. For in particular, for example, a change in speed can only take place within a limited time, but not arbitrarily fast.
- the first and the second information are present in the drive unit.
- the storage location within the drive unit is in principle arbitrary.
- the drive device stores the first and second information in a contiguous data area of the drive unit.
- the drive apparatus controls a plurality of electric motors is in the data area related to each other

For example, it is possible for the computer program to be cached in a mobile memory, for example in a USB memory stick or in a memory card. Alternatively, it is for example possible that the computer program 6 is stored in a mass memory of an external computer and the drive controller 1 is supplied via a computer-computer connection. A typical example of a computer-to-computer connection is the Internet or a LAN.

- the setpoint values x * may, as shown in FIGS. 2 and 3, in particular be position setpoint values p * or speed setpoint values n *.
- the drive control 1 can also determine its own sequence of desired values x '* for further electric motors 5'. These may in particular be setpoints x '* which are of the same type as the setpoint values x * for the electric motor 5. Thus, for example, it may also be position setpoint values p' * or likewise speed setpoint values n '*. However, it may also be another type of setpoint x '*.
- the drive controller 1 makes available each sequence of setpoint values x *, x '* via a communication connection 14 to that engine control unit 2 or 2' which acts on the respective electric motor 5, 5 ', for which the respective sequence of setpoint values x *, x '* is determined. If - in the case of two electric motors 5, 5 'by way of example - the engine control unit 2 acts on both electric motors 5, 5' (see FIG. 2), both sequences of desired values x *, x '* become available to the engine control unit 2 posed. If on the electric

- the engine control unit 2 evaluates a number of first signals B1 in a step S1. Based on the first signal Bl, the engine control unit 2 decides whether it accepts a monitoring operation. If it accepts the monitoring operation, it also decides - preferably within the scope of step S1 - which type is an actual value condition.
- the actual value condition can be, for example, that the electric motor 5 is monitored for maintaining a limit speed nmax and / or for maintaining a desired rotational direction D.

- the feeding of the first signals Bl can be effected, for example, by means of a terminal module assigned to the engine control unit 2 or by means of a programmable logic controller via a bus connection. These procedures are known in the art.
- the actual value condition initially depends on the type of monitoring operation. For example, can be determined by the supplied first signals Bl, whether the electric motor 5 to maintain a maximum allowable speed nmax and / or to maintain a predetermined rotational direction D. should be monitored. Furthermore, the engine control unit 2 can be specified from the outside, which value has the direction of rotation D, so for example, left-hand rotation or clockwise rotation. Also continuously variable values of the motor control 2 can be specified from the outside, for example, the limit speed nmax or a maximum permissible limit torque Mmax. Such signals, which parameterize the actual value condition, are referred to below as a second signal B2 to distinguish them from the first signals B1, which initiate or terminate the monitoring operation as such.

- the drive control 1 can determine the setpoint values x *, x '* for a plurality of electric motors 5, 5'.
- the procedure of FIG. 6 is carried out for each electric motor 5, 5 'controlled by the drive control 1.
- the drive control 1 takes into account any necessary coordination of the electric motors 5, 5 'with each other. This implies, in particular, that in the event that the engine control unit 2 monitors the actual value of the electric motor 5 for compliance with the actual value condition, the sequence of desired values x '* for the further electric motor 5' must also be determined taking into account the actual value condition, which actually only applies to the electric motor 5.
- the drive controller 1 preferably performs a motion guide.
- the term "motion control” means that the drive control 1 determines the sequences of desired values x *, x '* for the electric motors 5, 5' such that the corresponding actual values x, x 'correspond to the desired values x *, x' *
- the drive controller 1 is therefore designed as a motion control unit for production machines, as shown in FIG. 1, in particular as a numerical controller (CNC) for machine tools.

- the engine control unit 2 controls a plurality of electric motors 5, 5 ', as shown in FIG 8 for each of these electric motors 5, 5 'each of the first and second information Cl, C2 stored in the data area 16.
- the term should include that the engine control unit 2 transmits the first and the second information Cl, C2 to the drive control 1.
- a read-out unit 17 of the engine control unit 2 for example a microprocessor-reads from the data area 16 of the engine control unit 2 the first and second information C1, C2 and transmits it to the drive control 1.
- the drive control 1 takes the It is supplied with information C 1, C 2 by means of a read-in unit 18, for example likewise a microprocessor, and stores it in a data area 19 of the drive controller 1. From there it reads out the drive control 1 as needed.
- the transmission of the information Cl, C2 can be done cyclically, for example.
- the engine control unit 2 can transmit the first and the second information C1, C2 only on the basis of an external event.
- an event can be, for example, that the first and / or the second information Cl, C2 have changed or that the engine control unit 2 receives a request (polling) from the drive control 1 for the information C1, C2.
- the polling may optionally be cyclical in turn.
- the advantage of the procedure of FIG. 9 is that neither the engine control unit 2 nor the drive control 1 need to know where and how the first and second information C1, C2 are stored and managed by the respective other device 2, 1. If such knowledge is also assumed, it is possible, as an alternative to the procedure of FIG. 9, for the engine control unit 2 of the drive control 1 to allow at least one read access to the data area 16 of the engine control unit 2. In this case, the drive controller 1 according to FIG. 10 can directly access the data area 16 of the engine control unit 2 and read out the first and the second information C1, C2 therefrom. Such procedures are known per se under the term DMA (direct memory access).

- the actual value condition is time-variable. This will be explained in more detail below in conjunction with FIG.
- steps S21 to S23 can be inserted between the steps S1 and S2 (see also FIG. 4).
- step S21 the engine control unit 2 checks whether a duplicate condition is satisfied.
- a first part of the double condition is that the engine control unit 2 is in the monitoring mode.
- a second part of the double condition is that the monitoring mode was newly adopted, that is, the monitoring operation was not yet adopted in the immediately preceding run of the loop of FIG. 4. If both parts of the double condition are satisfied, the engine control unit 2 proceeds to step S22. Otherwise, the engine control unit 2 proceeds to step S2.
- Step S21 is divided into two sub-steps S21a and S21b in FIG. 12 for the sake of clarity.
- step S22 the engine control unit 2 checks whether the actual value of the engine 5 to be monitored already fulfills the actual value condition determined in step S1. If so, the engine control unit proceeds to step S2. Only if the actual value condition has not yet been fulfilled does the engine control unit 2 proceed to step S23. Step S22 is divided into two sub-steps S22a and S22b in FIG. 12 for the sake of clarity.
- step S23 the engine control unit 2 determines a time profile of the actual value condition as a function of the actual value condition and the instantaneous value of the actual value to be monitored, for example as a function of the deviation of the monitored actual value from a limit value to be maintained.
- a certain non-negligible time is required for braking the electric motor 5, that is to say despite proper control of the electric motor 5 and despite proper reaction of the electric motor 5 the actually desired actual value condition can not be met immediately.
- the procedure according to the invention has many advantages.
- the computer programs 6, 9 for the drive control 1 and the engine control unit 2 independently of the programs for all other modules - for example, a programmable logic controller - are created.
- no additional wiring is required.
- the drive controller 1 and in particular also the application program 12 can be created independently of the way in which the first control signal 2 is supplied to the engine control unit 2.
