Homing Procedures
There are five different homing patterns depending on the homing method that is specified in
PnB31 = n.X.
The homing procedure for each method is given in this section.
Using the /DEC Signal and Encoder Origin (Phase C) for
Homing (PnB31 = n.1)
Turn ON the power supply.
The ALM signal turns OFF.
Turn ON the /S-ON signal. The SERVO ON state is entered.
Turn ON the /HOME signal. Homing starts.
Turn OFF the /HOME signal after the /BUSY signal turns ON.
When the /DEC signal turns ON, the motor changes to the approach speed.
When the encoder’s origin signal (phase C) is detected, the motor decelerates to the creep
speed.
After the motor moves the final travel distance, homing has been completed and the /POS-
RDY signal turns ON.
