(2) Manual Adjustment of the Speed Reference Offset
Use the speed reference offset manual adjustment (Fn004) in the following situations:
·If a loop is formed with the host controller and the postion error pulse is set 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 (Fn003), except that the
amount of offset is directly input during the adjustment.
