CN3-6 Outputs pulses per servo motor revolution set in parameter No.PA15 in the differential
CN3-16 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 /2.
The relationships between rotation direction and phase difference of the A and B-phase
pulses can be changed using parameter No.PC03.
CN3-4
Output pulse specification and dividing ratio setting can be set. (Refer to section 5.1.10.)
