3.11 Timing Signal Detector Specifications

The timing signal detector is composed of a detection slit mounted on the motor shaft, a photo interruptor, and waveform shaping circuit.

Timing signal 1 is generated 18 pulses and timing signal 2 is generated 1 pulse every time the motor rotates by 1 turn.
