Abstract
A switching device for controlling at least two motors has a single converter, wherein the at least two motors are connected to the converter by a power line and a feedback line, respectively. At least one logic module is connected to the converter and evaluates signals received from the converter to generate a control signal for controlling the motors. The converter has an interface for selecting one of the motors to be controlled, wherein the interface is connected by a signal line to the at least one logic module. The power lines and the feedback lines each have a switch. The at least one logic module is adapted to switch with the control signal at least two of the switches for switching the respective power line and the respective feedback line of the motor to be controlled.
Claims19
A switching device comprising:
- at least two motors each having a feedback sensor;
- a single servo amplifier converter, wherein the at least two motors are connected to the single servo amplifier by a power line and a feedback line for returning feedback signals for evaluation, respectively;
- wherein the power lines and the feedback lines each have a power switch;
- a logic module connected to the single servo amplifier and configured to evaluate signals received from the single servo amplifier and configured to generate control signals;
- wherein the power switches are actuated by the control signals received from the logic module for selectively switching one of the at least two motors.
A switching device comprising:
- at least two motors;
- a single servo amplifier connected to the at least two motors;
- a multiplexer arranged downstream of the single servo amplifier;
- a decoder connected to the multiplexer for controlling the multiplexer;
- encoder lines connecting the single servo amplifier to the decoder for triggering the multiplexer;
- wherein the at least two motors each have a bidirectional driver connected by bidirectional data lines to the multiplexer;
- wherein the bidirectional drivers send signals to the at least two motors to be controlled;
- wherein the bidirectional drivers are directionally switched by signals received from the decoder.
