LB-A
LBR-A
CN3-4
CN3-17
Outputs pulses per servo motor revolution set in parameter No.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 /2.
The relationships between rotation direction and phase difference of the A and B-phase
pulses can be changed using parameter No.PC03.
Output pulse specification and dividing ratio setting can be set. (Refer to section 5.1.10.)

DICOM
CN3-23
Used to input 24VDC (24VDC 10 250mA) for I/O interface of the servo amplifier. The
power supply capacity changes depending on the number of I/O interface points to be
used.
For the sink interface, connect of 24VDC external power supply.
For the source interface, connect of 24VDC external power supply.
