Homing

Homing starts when the /HOME signal becomes active.
Homing stops if the /HOME signal becomes inactive again.
If the /HOME signal becomes active again while the homing is stopped, homing will be restarted from the
point where it was interrupted.
The homing will be canceled if operation is switched to JOG speed table mode with the /JOGP signal or /
JOGN signal, or the mode is switched with the /MODE 0/1 signal while the homing is stopped.
When parameter PnB31 = 0 (No homing), homing will end as soon as the control power supply is turned ON.
The smaller of the settings in parameter PnB29 (Acceleration) and PnB2B (Deceleration) will be used as the
homing acceleration and deceleration rate.
Note 1. When PnB31 is set to 0, homing cannot be done by the /HOME signal. If so, an E5DE error will occur.
2. Homing is available when an incremental encoder is used. When an absolute encoder is used, an E61E error will
occur if the /HOME signal is active.
 /DEC and phase C of the encoder are used for homing (PnB31 = 1).
