5.5.2 Reference Offset Adjustment

5-48

(1) Automatic Adjustment of Reference Offset (Fn009)

The automatic adjustment of reference offset measures the amount of offset and adjusts the reference voltage

automatically.
After completion of the automatic adjustment, the amount of offset measured is saved in the SERVOPACK.

Note: The adjusted value is not initialized by executing the Fn005 function (Initializing Parameter Settings).

Preparation

The following conditions must be met to adjust the offsets of torque analog reference automatically. The mes-

sage “NO-OP” indicating that the settings are not appropriate will be displayed, if the following conditions are
not met.

• The write prohibited setting parameter (Fn010) must be set to Write permitted (P.0000).
• The servomotor power must be OFF.

Operating Procedure

Adjust the reference offset automatically with the panel operator using the following steps.

Note: The automatic adjustment of reference offset (Fn009) cannot be used when a position loop has been formed with the

host controller. Use the manual adjustment of reference offset described in (2) Manual Adjustment of Reference Off-
set (Fn00B)
.

The servomotor power must be OFF when automatically adjusting the reference offset.
