7.2.11 Adjusting the Motor Current Detection Offset
Motor current detection offset adjustment is performed at Yaskawa before shipping.

only if highly accurate adjustment is required to reduce torque ripple caused by
current offset.
The following sections describe automatic and manual adjustment of the current
detection offset.
