Es ist Aufgabe der Erfindung, eine Werkzeugmaschine, Produktionsmaschine und/oder einen Roboter zu schaffen, bei dem Betriebsdaten eines Motors der Werkzeugmaschine, Produktionsmaschine und/oder des Roboters zuverlässig ermittelt und am Motor gespeichert werden können, ohne dass dafür eine Erfassungseinrichtung, wie z.B. ein Betriebsstundenzähler, am Motor selbst angeordnet werden muss.It is the object of the invention to provide a machine tool, a production machine and / or a robot, in which operating data of an engine of the machine tool, production machine and / or robot can be reliably determined and stored on the engine without the need for a detection device, e.g. an operating hours counter, must be arranged on the engine itself.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im Folgenden näher erläutert. Dabei zeigt die Figur eine erfindungsgemäße Werkzeugmaschine, Produktionsmaschine und/oder einen Roboter.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.

In der Figur ist in Form einer schematisierten Darstellung eine Maschine 14, die als Werkzeugmaschine, Produktionsmaschine und/oder als Roboter ausgebildet sein kann, dargestellt. Die Maschine 14 weist eine Einrichtung zur Steuerung und/oder Regelung eines elektrischen Motors 6 der Maschine 14 auf, wobei im Rahmen des Ausführungsbeispiels die Einrichtung zur Steuerung und/oder Regelung in Form einer Steuereinrichtung 1 vorliegt, die im Wesentlichen Steuerungsfunktionalitäten ausführt. Die Steuereinrichtung 1 kann dabei z.B. in Form einer NC-Steuerung (Numerical Control) vorliegen. Die Steuereinrichtung 1 weist eine Sollwertermittlungseinheit 12 auf, die Lagesollwerte ermittelt und über eine Verbindung 2 an eine Regeleinrichtung 3 als Regelsollwerte zur Regelung eines elektrischen Motors 6 übermittelt. Die Lage des Rotors des Motors 6 wird von einem Geber 10 gemessen und als Regelistwerte an die Regeleinrichtung 3 übermittelt, was durch einen Pfeil 11 in der Figur dargestellt ist. Die Regeleinrichtung 3 gibt ausgangsseitig über eine Verbindung 4, Stromsollwerte an einen Umrichter 5 aus, der entsprechend den Stromsollwerten, über elektrische Leitungen 8, einen Motor 6 ansteuert und mit elektrischer Energie versorgt. Der Motor 6 weist einen Speicher 7 zur Speicherung von Daten auf, wobei der Speicher 7 z.B. am Motorgehäuse angeordnet sein kann. Der Umrichter 5 ist zur Übermittelung von Daten an den Speicher 7 mit dem Motor 6 über eine Verbindung 15 verbunden. Der Motor 6 treibt eine Last 9 an, die z.B. in Form einer Vorschubeinheit oder einer Werkzeugspindel ausgebildet sein kann.In the figure, in the form of a schematic representation of 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 Regelistwerte 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.

Die Regeleinrichtung 3, der Umrichter 5 und der Motor 6 bilden einen Antrieb der Maschine 14, wobei die Maschine 14 in der Regel über mehrere solcher Antriebe verfügt, an die die Sollwertermittlungseinheit 12 dem jeweiligen Antrieb zugeordnete Sollwerte übermittelt. Der Übersichtlichkeit halber ist in der Figur nur ein einzelner Antrieb dargestellt.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.

Erfindungsgemäß weist die Steuereinrichtung 1 eine Motorbetriebsdatenermittelungseinheit 13 zur Ermittelung von Motorbetriebsdaten des Motors 6 und falls vorhanden gegebenenfalls noch von weiteren Motoren der Maschine 14 auf. Als Motorbetriebsdaten werden dabei Daten verstanden, welche Rückschlüsse auf die Belastung des Motors 6, die während dem Betrieb des Motors 6 aufgetreten sind, zulassen. Als Motorbetriebsdaten können so z.B. die Betriebsstunden des Motors und/oder die Anzahl der Umdrehungen des Motors während der Betriebszeit und/oder die Drehzahlen des Motors mit der der Motor betrieben worden und/oder die Drehmomente des Motors, die während des Betriebs des Motors aufgetreten sind und/oder die Beschleunigungen des Motors, die während des Betriebs des Motors aufgetreten sind, und/oder die Motorströme die während des Betriebs des Motors aufgetreten sind, von der Motorbetriebsdatenermittelungseinheit 13 ermittelt werden.According to the invention, 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. As 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. As 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.

Zur Ermittlung der Motorbetriebsdaten werden z.B. von der Motorbetriebsdatenermittlungseinheit 13 z.B. die während dem Betrieb des Motors 6 auftretenden Steuerungs- und Regelungsgrößen, wie z.B. die Regelsollwerte, Regelistwerte, Stromsollwerte und/oder gemessene Motorströme, benutzt. Die entsprechenden Werte werden hierzu z.B. von der Sollwertermittlungseinheit 12 an die Motorbetriebsdatenermittlungseinheit 13 und von der Regeleinrichtung 3 und dem Umrichter 5 über die Verbindungen 2 und 4 an die Motorbetriebsdatenermittlungseinheit 13 übertragen. Die Motorbetriebsdatenermittlungseinheit 13 ermittelt dann z.B. über die Beziehung M = i soll k

k: Konstante (abhängig vom jeweiligen Motor, Getriebe)
aus dem von der Regeleinrichtung 3 dem Umrichter 5 vorgegebenen Motorsollstrom isoll (Motorsollwerte) das Drehmoment M des Motors 6. Die Beschleunigung des Motors kann z.B. durch zweimaliges Ableiten nach der Zeit der von der Sollwertermittlungseinheit 12 ermittelten Lagesollwerte berechnet werden.To determine the engine operating data, for example, 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. For this purpose, 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 engine operation data acquiring unit 13 then determines, for example, about the relationship M = i should k
Figure imgb0001
k: constant (depending on the engine, transmission)
i from the set by the controller 3 to the inverter 5 motor target current is (engine target values), the torque M of the motor 6. 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.

Die Motorbetriebsdaten können aber z.B. alternativ oder zusätzlich auch in Form von Belastungsdaten, welche aus den oben genannten Größen ermittelt werden vorliegen. So können z.B. die Belastungsdaten in Form von Mittelwerten, Maximalwerten und/oder über einen längeren Betriebszeitraum häufig aufgetretene Werte (maßgebliche Werte) der Drehzahlen und/oder der Drehmomente und/oder der Beschleunigungen mit der der Motor betrieben wurde, vorliegen. Die Motorbetriebsdaten werden dabei vorzugsweise zusammen mit einer entsprechenden Zeitbasis abgespeichert, so dass später nachvollzogen werden kann, wann die Belastungen aufgetreten sind.However, 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. For example, 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.

Die solchermaßen ermittelten Motorbetriebsdaten werden, vorzugsweise in regelmäßigen Abständen, von der Steuereinrichtung 1 über die Verbindungen 2, 4 und 15 an den Speicher 7 übermittelt und in dem Speicher 7 gespeichert.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.

Eine Erfassungseinheit, wie z.B. ein separater Betriebsstundenzähler für die Motorbetriebsdaten, welche am Motor 6 angeordnet ist, kann somit entfallen. Der Motor 6 muss somit für die Erfindung nur minimal verändert werden, indem z.B. ein Speicher 7 am Motorgehäuse angeordnet wird.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.

Die Motorbetriebsdatenermittlungseinheit 13 muss dabei nicht notwendigerweise wie im Ausführungsbeispiel in der Steuereinrichtung 1 integriert sein, sondern kann auch in die Regeleinrichtung 3 oder in den Umrichter 5 integriert sein, was durch die Bezugszeichen 13' und 13" in der Figur gestrichelt gezeichnet dargestellt ist. Es sei an dieser Stelle angemerkt, dass die Steuereinrichtung 1 und die Regeleinrichtung 3 auch eine bauliche Einheit bilden können. Die Regeleinrichtung 1 stellt ein Beispiel für eine Einrichtung zur Regelung eines elektrischen Motors dar, wobei in der Regeleinrichtung 1 im Wesentlichen Regelungsfunktionalitäten ablaufen, wobei der Umrichter auch in die Regeleinrichtung integriert sein kann.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.

Die Kombination von Steuereinrichtung 1 und Regeleinrichtung 3, sowie die Kombination von Steuereinrichtung 1, Regeleinrichtung 3 und Umrichter 5 stellen jeweils ein Beispiel für eine Einrichtung zur Steuerung und Regelung eines elektrischen Motors dar, wobei anstatt des Umrichters auch ein anderer Stromrichter verwendet werden kann.The combination of control device 1 and control device 3, as well as the combination of control device 1, control device 3 and inverter 5 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.

Die im Speicher 7 gespeicherten Motorbetriebsdaten lassen sich mit Hilfe einer am Motorgehäuse angeordneten Schnittstelle auslesen.The engine operating data stored in the memory 7 can be read out by means of an interface arranged on the motor housing.

Es sein an dieser Stelle angemerkt, dass die Sollwertermittelungseinheit und die Motorbetriebsdatenermittlungsseinheit in der Regel in Form von Software realisiert sind.It should be noted at this point that the setpoint determination unit and the motor operation data acquiring unit are usually realized in the form of software.
