Note: Repeat the above operations (phase-U and-V alternately) until adjusting the offset amounts both for
phase-U and-V in both directions cannot reduce the torque ripple any more.
Then, perform the same operation by adjusting by smaller amount.

Description
Press the Key to open the Utility Func-
tion Mode main menu, and select Fn00F
using the or
Press the Key.
The display is switched to the execution dis-
play of Fn00F (Manual offset-signal adjust-
ment of the motor current detection).
Adjust the phase-U offset.
Press the or
set amount.
Adjust the offset amount by 10 in the direc-
tion that the torque ripple is reduced. (ZAD-
JIU: Phase-U current zero-adjustment)
Adjust the phase-V offset.
Press the Key. The cursor moves to the
phase-V side.
Press the or
set amount.
Adjust the offset amount by 10 in the direc-
tion that the torque ripple is reduced. (ZAD-
JIV: Phase-V current zero-adjustment)
When the offset adjustment is completed,
press the Key to save the result of
adjustment in the SERVOPACK.
When the saving is completed, "Done" is dis-
played in the status display.
