Note: The automatic adjustment of reference offset (Fn009) cannot be used when a position loop has been formed with a
host controller. Use the manual servo tuning of reference offset described in (2) Manual Adjustment of Reference
Offset (Fn00A).
(2) Manual Adjustment of Reference Offset (Fn00A)
This method adjusts the offset inputting the amount of reference offset directly.
Use the manual servo tuning of reference offset (Fn00A) in the following cases:
• If a position loop is formed with the host controller and the error is zeroed when servolock is stopped.
• To deliberately set the offset to some value.
• To check the offset data set in the automatic adjustment mode of reference offset.
Adjust the reference offset using following steps.
