3.5.2 Manual Servo Tuning of the Speed Reference Offset

Use the speed reference offset manual servo tuning (Fn00A) in the following cases:
• If a loop is formed with the SVA-01 Module 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 speed reference offset automatic adjustment mode
This function operates in the same way as the reference offset automatic adjustment mode (Fn009), but the manual
