5.2.6 Offset-adjustment of Servomotor Current Detection Signal
Automatic servomotor current detection offset adjustment is performed at ESTUN before shipping. Basically, the user
does not need to 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.
Note ：
· 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 the OFF state.
· Execute the automatic offset adjustment if the torque ripple is too big when compared with that of other servo
drives.
· If this function, particularly manual adjustment, is executed carelessly, it may worsen the characteristics.
