Homing Based on User-Specified Position（No.645.0=0）
This operation indicates the type of homing based on the starting point.
This type of homing operation enables you to specify any position as the home position without turning the
servo on, for example, by manually moving the machine to any desired home position. In addition, this method
enables the encoder z-phase to be detected without involving stopper or
sensor
This type of homing does not involve the Rough Approach motion group.
Set the following related parameters.
*) Parameters to define the homing pattern
Refer to the patterns from 1 to 6 below to set the parameters.
