The setting value of this item indicates pulses of the encoder, and is independent of the electronic

gear setting. The number of pulses of the encoder varies depending on the type of actuator. See (8),

[A]


Set the amount of movement from the position at which phase Z is detected after reversing at the
mechanical end in a push operation, for the homing operation.

An appropriate value corresponding to the applicable actuator has been set at shipment from the factory.
