7.2.8 Automatic Offset-adjustment of Motor Current Detection Signal (Fn00E)
Automatic motor current detection offset adjustment has performed at Yaskawa before shipping. Basically, the

Perform this adjustment only if highly accurate adjustment is required for reducing torque ripple caused by cur-
rent offset. Automatic adjustment is possible only while power is supplied to the main circuit power supply and
with the servo is OFF.
1. Execute the automatic offset adjustment if the torque ripple is too big when compared with that of other
SERVOPACKs.

Automatic adjustment is possible only while power is supplied to the main circuit power supply
and with the servo is OFF.
