Outputs the zero-point signal of the encoder. One pulse is
output per servo motor revolution. OP turns on when the
zero-point position is reached. (Negative logic)
The minimum pulse width is about 400 s. For home
position return using this pulse, set the creep speed to
100r/min. or less.

Outputs pulses per servo motor revolution set in
parameter No. 27 in the differential line driver system.
In CCW rotation of the servo motor, the encoder B-phase
pulse lags the encoder A-phase pulse by a phase angle of
/2.
The relationships between rotation direction and phase
difference of the A B-phase pulses can be changed using
parameter No. 54.
