After completion of the automatic adjustment, the amount of offset is saved in the SERVOPACK.
Adjust the reference offset automatically using the following steps.
Note: The automatic adjustment of reference offset (Fn009) cannot be used when a position loop has been formed with the
host controller. Use the manual servo tuning of reference offset described in (2) Manual Adjustment of Reference
Offset (Fn00B).
The reference offset must be automatically adjusted while the servo ON (/S_ON) signal
is OFF.
