6.12.2 Manual Adjustment

You can use this function if you automatically adjust the motor current detection signal offset
and the torque ripple is still too large.
Important
Information
6-30
If the offset is incorrectly adjusted with this function, the Servomotor characteristics may be
adversely affected.
Observe the following precautions when you manually adjust the offset.
• Operate the Servomotor at a speed of approximately 100 min
• Adjust the offset while monitoring the torque reference with the analog monitor until the ripple is
minimized.
• Adjust the offsets for the phase-U current and phase-V current of the Servomotor so that they
are balanced. Alternately adjust both offsets several times.
The offset does not use a parameter, so it will not change even if the parameter settings are
initialized.
