7.2.11. Adjusting the Motor Current Detection Offset

Motor current detection offset adjustment is performed at Yaskawa
before shipping. Normally, the user does not need to perform this
adjustment. Make this adjustment only if highly accurate adjustment is
required to reduce torque ripple caused by current offset.
•
If this function, particularly manual adjustment, is executed carelessly, it may degrade
the performance of the servo drive.
The following sections describe automatic and manual adjustment of
the current detection offset.
