Definitions

  • the invention relates to a machine tool, production machine and / or a robot, with a device for controlling and / or regulating an electric motor of the machine tool, production machine and / or the robot. Furthermore, the invention relates to a method for securing operating data of an electric motor of a machine tool, production machine and / or a robot.
  • Machine tool, production machines and / or robots generally have a plurality of motors by means of which loads and in particular machine elements are driven. If such an engine fails during operation, the engine is removed and sent to the engine manufacturer for repair. For quick error analysis and quick troubleshooting, it would be of great advantage for the engine manufacturer if he knew the loads that had occurred in operation of the engine which the engine was exposed to.
  • From the DE 27 35 117 A is a plug-in device with a counter with drive for detecting operating times for portable devices known.
  • a detection device e.g. an operating hours counter
  • a machine tool, production machine and / or robot with a device for controlling and / or regulating an electric motor of the machine tool, production machine and / or the robot, wherein the motor has a memory, wherein engine operating data of the engine of the device can be determined, from the device to the memory can be transmitted and stored in the memory.
  • this object is achieved by a method for securing operating data of an electric motor of a machine tool, production machine and / or a robot, wherein motor operating data of the motor is determined by a device for controlling and / or regulating the motor of the machine tool, production machine and / or the robot wherein the engine has a memory, the engine operating data being transmitted from the device to the memory and stored in the memory.
  • Advantageous embodiments of the method are analogous to the advantageous embodiment of the machine tool, production machine and / or the robot and vice versa.
  • the operating data from the device to the memory at regular intervals can be transmitted. This measure ensures that the engine operating data, which are stored in the memory of the engine, are updated at regular intervals and thus include the current engine operating data status.
  • FIG. 1 An embodiment of the invention is illustrated in the drawing and will be explained in more detail below.
  • the figure shows a machine tool according to the invention, production machine and / or a robot.
  • a machine 14 which may be formed as a machine tool, production machine and / or robot, represented.
  • the machine 14 has a device for control and / or control of an electric motor 6 of the machine 14, wherein in the context of the embodiment, the device for controlling and / or regulating is in the form of a control device 1, which executes substantially control functionalities.
  • the control device 1 can be present eg in the form of an NC control (Numerical Control).
  • the control device 1 has a setpoint determination unit 12, which determines position setpoint values and transmits them via a connection 2 to a control device 3 as setpoint control values for controlling an electric motor 6.
  • the position of the rotor of the motor 6 is measured by an encoder 10 and transmitted as crizistept to the control device 3, which is shown by an arrow 11 in the figure.
  • the control device 3 outputs on the output side via a connection 4, current setpoint values to a converter 5 which, in accordance with the current setpoint values, drives a motor 6 via electrical lines 8 and supplies them with electrical energy.
  • the motor 6 has a memory 7 for storing data, wherein the memory 7 may be arranged, for example, on the motor housing.
  • the inverter 5 is connected to the data transmission to the memory 7 to the motor 6 via a connection 15.
  • the motor 6 drives a load 9, which may be formed, for example, in the form of a feed unit or a tool spindle.
  • the control device 3, the converter 5 and the motor 6 form a drive of the machine 14, wherein the machine 14 usually has a plurality of such drives, to which the setpoint determination unit 12 transmits setpoint values assigned to the respective drive. For the sake of clarity, only a single drive is shown in the figure.
  • the control device 1 has an engine operating data acquisition unit 13 for determining engine operating data of the engine 6 and, if appropriate, also of other engines of the engine 14.
  • engine operating data is understood to mean data which conclusions on the load of the motor 6, which have occurred during operation of the engine 6, allow.
  • engine operating data For example, the engine hours and / or the number of revolutions of the engine during operation and / or the engine revolutions with which the engine has been operated and / or the engine torques that have occurred during engine operation and / or or the accelerations of the engine that occurred during operation of the engine, and / or the engine currents that occurred during operation of the engine are determined by the engine operating data determination unit 13.
  • the engine operating data determination unit 13 uses, for example, the control and regulation variables occurring during operation of the engine 6, such as the control setpoints, control actual values, current setpoint values and / or measured motor currents.
  • the corresponding values are, for example, transmitted from the setpoint determination unit 12 to the motor operating data determination unit 13 and from the control unit 3 and the converter 5 via the connections 2 and 4 to the motor operating data determination unit 13.
  • the acceleration of the motor can for example by taking the second derivative with respect to time of the position values determined by the desired value determination unit 12 are calculated.
  • the engine operating data can also be present, for example alternatively or additionally, in the form of load data which are determined from the variables mentioned above.
  • the load data may often be in the form of averages, maximum values and / or over a longer period of operation occurred values (relevant values) of the speeds and / or the torques and / or the accelerations with which the engine was operated, are present.
  • the engine operating data are preferably stored together with a corresponding time base, so that it can be later understood when the loads have occurred.
  • the thus determined engine operating data are transmitted, preferably at regular intervals, from the control device 1 via the connections 2, 4 and 15 to the memory 7 and stored in the memory 7.
  • a detection unit such as a separate operating hours counter for the engine operating data, which is arranged on the engine 6, can thus be dispensed with.
  • the motor 6 thus needs to be minimally changed for the invention by e.g. a memory 7 is arranged on the motor housing.
  • the engine operating data determination unit 13 does not necessarily have to be integrated in the control device 1 as in the exemplary embodiment, but may also be integrated in the control device 3 or in the converter 5, which is shown by dashed lines in the figure by reference numbers 13 'and 13 " It should be noted at this point that the control device 1 and the control device 3 can also form a structural unit
  • the control device 1 represents an example of a device for controlling an electric motor, wherein in the control device 1 substantially run control functions, wherein the inverter can also be integrated in the control device.
  • control device 1 and control device 3 each represent an example of a device for controlling and regulating an electric motor, wherein instead of the converter, another power converter can be used.
  • the engine operating data stored in the memory 7 can be read out by means of an interface arranged on the motor housing.
  • setpoint determination unit and the motor operation data acquiring unit are usually realized in the form of software.
