Abstract
A converter assembly, a method for producing a converter assembly and a method for operating a converter assembly are described, in which a base module includes power electronics and control electronics. The base module includes a housing, particularly a housing part at least partially forming a housing for the power electronics and control electronics. The base module includes an electrical and mechanical interface, via which signal electronics are able to be joined to the base module with form-locking and/or force-locking, in order to form the converter assembly. The signal electronics include a housing, especially so that after being joined, the housing of the signal electronics and the housing of the base module together form a housing of the converter assembly. A setpoint value for speed and/or torque is transmittable electrically via the interface, the signal electronics having means for receiving, determining and/or inputting the setpoint value.

24. A method for operating a converter assembly, comprising:
-
supplying a setpoint value for torque and/or speed by signal electronics to control electronics via an interface, supplying an acquired value for motor current and/or angular value of a rotor shaft to the control electronics, determining an actual value for torque and/or speed which is adjusted by an automatic control unit of the control electronics to a setpoint value by determining a motor voltage as manipulated value, or by determining corresponding pulse-width-modulated driving signals that are supplied to power semiconductor switches, determining the setpoint value for torque and/or speed by an automatic control unit of the signal electronics as manipulated value of a controlled variable of the automatic control unit of the signal electronics, supplying the setpoint value and an actual value of a variable of a position of a part driven by a motor energized by the converter assembly to the signal electronics, and determining a deviation between the setpoint value and the actual value, and determining the manipulated value by the automatic control unit of the signal electronics. - View Dependent Claims (25)
