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.
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.
Important
• 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
