4.4.12 Dogless Z-phase reference home position return type

A position, which is shifted to by the home position shift distance from a position specified by the Z-phase
pulse right after the start of the home position return, is set as the home position.

_ _ _ A: Select the dogless type (Z-phase
reference).
Refer to section 4.4.1 (2) to select the home
position return direction.
Set the rotation speed specified until the Z-
phase is detected.
Set the rotation speed specified after the Z-
phase is detected.
Set this to shift the home position, which is
specified by the Z-phase signal.
The acceleration/deceleration time constant
of point table No. 1 is used.
Set the current position when the home
position return is complete.
