(Open collector)
Encoder A-phase LA
pulse
(Differential line LAR

No.
CN1A Outputs the zero-point signal of the encoder. One pulse is output
14 per servo motor revolution. OP and LG are connected when the
zero-point position is reached. ( Negative logic)
The maximum pulse width is about 400 s. For zeroing using this
pulse, set the creep speed to 100r/min. or less.
CN1A Outputs pulses per servo motor revolution set in parameter No.
6 27 in the differential line driver system. The encoder B-phase
CN1A pulse lags the encoder A-phase pulse by a phase angle of /2.
