7.2.6 Automatic Offset-adjustment of Motor Current Detection Signal (Fn00E)
Automatic 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. Automatic adjustment is possible only with power supplied to the main circuit power supply and with
the servo OFF.
Execute the automatic offset adjustment if the torque ripple is too big when compared with that of other
SERVOPACKs.
