Description
direction
Forward
Although this type is the same as the dog cradle type homing, the stop position
rotation
is not on the Z-phase. Starting from the front end of the dog, the position is
shifted by the travel distance after proximity dog and the home position shift
distance. The position after the shifts is set as the home position.
Reverse
This is the same as the dog type front end reference homing.

Reverse
Although this type is the same as the dogless Z-phase reference homing, the
rotation
creep speed is applied as the movement start speed.

The current position is set as the home position. This type can be executed even
when the servo amplifier is not in the Operational enabled state.
