These devices output pulses of encoder output pulse set in [Pr. PA15] in
the differential line driver type.
In CCW rotation of the servo motor, the encoder B-phase pulse lags the
encoder A-phase pulse by a phase angle of
π
/2.
The relation between rotation direction and phase difference of the A-
phase and B-phase pulses can be changed with [Pr. PC19].

The encoder zero-point signal is outputted in the differential line driver
type. One pulse is outputted per servo motor revolution. This turns on
when the zero-point position is reached. (negative logic)
The minimum pulse width is about 400 µs. For home position return using
this pulse, set the creep speed to 100 r/min or less.

OP
CN1-33 The encoder zero-point signal is outputted in the open-collector type.
