Abstract: To test a controller for a motor having a position feedback signal, a simulation circuit programmable by test equipment replaces the actual motor and emulates motors of various types. Motor direction command signals from the controller are detected by comparators in the simulation circuit and a counter is incremented or decremented according to the detected command. The initial count value, representing a beginning motor position and the count rate of change, representing motor speed, are programmed by the test equipment. The count is converted with high resolution to an analog feedback signal which is coupled to the controller.
