(Open collector)
OP CN1-33 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.

CN1-4
CN1-5
Outputs pulses per servo motor revolution set in parameter No.PA15
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- and B-phase pulses can be changed using parameter No.
