12 DATA USED FOR POSITIONING CONTROL
12.3 Basic Setting
[Pr.53] Home position shift amount
Set the amount to shift (move) from the position stopped at with machine home position return.
*1 The home position shift function is used to compensate the home position stopped at with machine home position return.
If there is a physical limit to the home position, due to the relation of the near-point dog installation position, use this function to
compensate the home position to an optimum position.
[Pr.54] Home position return torque limit value
Set the value to limit the servomotor torque after reaching the creep speed during machine home position return.
Refer to the following for details on the torque limits.
