15.3.5 The Stopping Position is OFF for a Home Return
Conditions
When a home return is carried out, there is a possibility that the speed cannot be slowed sufficiently.
If deceleration cannot be continued down to the startup speed, the unit will not stop even if there is home
input.
Solution 1
Try shifting the position of the near home input switch in the direction of the home return,and in the
opposite direction.
Point to check:
If the home input is connected to the Z phase of the servo motor driver, there may be cases in which the
near home input position is close to the home input.
Solution 2
Correct the program and set the home return speed to a slower speed.
