(2) Manual Adjustment of the Speed Reference Offset
Use the speed reference offset manual adjustment (Fn00A) in the following situations:
• If a loop is formed with the host controller and the position error pulse is to be zero when servolock is
stopped.
• To deliberately set the offset to some value.
• To check the offset data set in the speed reference offset automatic adjustment mode.
This function operates in the same way as the reference offset automatic adjustment mode (Fn009), except that
the amount of offset is directly input during the adjustment.
The offset setting range and setting units are as follows:
Adjust the speed reference offset manually in the following procedure.
