Electronic circuit for automatic restart of stepper- and servo-motors

摘要

As soon as the motors have reached the next programmed position and the run-latches RLx (x is the motor number) are off, the new data for the next position, the step frequency (for stop motors), the analogue voltage (for servo motors) and the direction of rotation CW/CCW (clockwise or counter-clockwise) are transmitted from the buffer resister to the working register. In fact, the next positions go from the position buffer register PBx to the position comparison register PCx, the direction of rotation from the monitoring buffer register CBx to the monitoring register CRx, and to the generator FGx or the D/A converter DACx.
