Home reference position
Homing based on Press (Stopper)（No.645.0=1）
This operation indicates the type of homing based on the stopper position.
You can use this type of homing by setting the home based on the position of the stopper being pressed per
the motor movement.
There are three options to
define
home” (after detection of stopper pressed motion): 1) stopper position, 2)
encoder z-phase, 3) user-specified position shifted from stopper or z-phase.
Set the following parameters related to this type of homing.
Refer to the patterns 7 to 12 to configure the parameters.
