7.2.7 Offset Adjustment of Motor Current Detection Signal (Fn00E, Fn00F)
Motor current detection offset adjustment has performed at Yaskawa before shipping. Basically, the user need not
perform this adjustment.
Perform this adjustment only if highly accurate adjustment is required for reducing torque ripple caused by cur-
rent offset. This section explains automatic offset-adjustment and manual offset adjustment.
(1) Automatic Offset Adjustment of Motor Current Detection Signal (Fn00E)
1. Execute the automatic offset adjustment if the torque ripple is too big when compared with that of other
SERVOPACKs.
2. Automatic adjustment is possible only while power is supplied to the main circuit and the servo is OFF.
