Manually Adjusting the Speed Reference Offset
You can directly input a speed reference offset to adjust the speed reference. The offset is
adjusted manually in the following cases.
• When a position loop is created with the host computer and the position deviation when the
Servomotor is stopped by a servo lock is to be set to 0
• To intentionally set the offset to a desired value
• To check an offset that was set automatically
Preparations
The following conditions must be met to manually adjust the reference offset.
• The parameters must not be write prohibited.
• The servo must be in ready status.
Applicable Tools
The following table lists the tools that you can use to manually adjust the speed reference offset
and the applicable tool functions.
Operating Procedure

1.
Input a 0-V reference voltage from the host controller or an external circuit.
2.
Click the Servo Drive Button in the workspace of the Main Window of the SigmaWin+.
