13.2.3 Homing Procedures
13-8
Using Only the /DEC Signal for Homing (PnB31 = 0002h)
 Turn ON the /HOME signal. Homing starts. The motor will rotate in the direction specified in
PnB32 (Homing Direction) at the speed specified in PnB35 (Approach Speed).
 When the /DEC signal turns ON, the motor decelerates to the creep speed.
 Homing is completed after the motor moves the final travel distance. Set PnB25 to the value
of the current position where the motor is stopped.
Using Only the Encoder Origin (Phase C) for the Homing
(PnB31 = 0003h)
 Turn ON the /HOME signal. Homing starts. The motor will rotate in the direction specified in
PnB32 (Homing Direction) at the speed specified in PnB35 (Approach Speed).
 When the encoder’s origin signal (phase C) is detected, the motor decelerates to the creep
speed.
 Homing is completed after the motor moves the final travel distance. Set PnB25 to the value
of the current position where the motor is stopped.
