7.10 Automatic Offset-Signal Adjustment of the Motor Current
Detection (Fn00E)
Perform this adjustment only if highly accurate adjustment is required for reducing torque ripple caused by
current offset. Basically, the user need not perform this adjustment.
Follow the steps below.
• Be sure to perform this function while the servo ON (/S_ON) signal is OFF.
• Execute the automatic offset adjustment if the torque ripple is too big when compared
with that of other SERVOPACKs.
