5.2.6 Offset-adjustment of Servomotor Current Detection Signal
Automatic servomotor current detection offset adjustment has performed at ESTUN 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 current offset.
This section describes the automatic and manual servomotor current detection offset adjustment.

Adjust the servomotor current detection signal automatically in the following procedure.
1. Press the MODE key to select the utility function mode.
2. Press the INC or DEC key to select the utility function number Fn005.
3. Press the ENTER key to enter into the automatic adjustment of the servomotor current detection
signal mode.
4. Press the MODE key,the display will blinks for one second. The offset will be automatically adjusted.
5. Press the ENTER key to return to the utility function mode display Fn005.
Thus, the automatic offset-adjustment of the servomotor current detection signal is completed.

：
·Offset-adjustment of the servomotor current detection signal is possible only while power is
supplied to the main circuit power supply and with the servo is OFF.
·Execute the automatic offset adjustment if the torque ripple is too big when compared with that
of other servodrives.
·If this function, particularly manual adjustment, is executed carelessly, it may worsen the
characteristics.
