7.11 Current Offset Automatic Adjustment (Fn103)
7.11.1 Overview
This function is only used when it is necessary to further reduce the torque ripple and other
adjustments that need to be performed with higher precision, and usually does not require
adjustment.
7.11.2 Operating Procedure
7.12 Current Offset Manual Adjustment (Fn104)
7.12.1 Overview
This function is used only when the torque ripple is still large after the motor current detection
signal offset automatic adjustment (Fn103) is executed.

Cautions
！
1. The automatic adjustment of the motor current detection signal offset must be performed while the servo
is off.
2. When the generated torque ripple is significantly larger than other servo units, perform automatic
adjustment of the offset.
