Adjusting the Motor Current Detection Signal Offset
The motor current detection signal offset is used to reduce ripple in the torque. You can adjust
the motor current detection signal offset either automatically or manually.
6.12.1
Automatic Adjustment
Perform this adjustment only if highly accurate adjustment is required to reduce torque ripple.
It is normally not necessary to adjust this offset.
Preparations
The following conditions must be met to automatically adjust the motor current detection signal
offset.
•
The parameters must not be write prohibited.
•
The servo must be in ready status.
•
The servo must be OFF.
Applicable Tools
The following table lists the tools that you can use to automatically adjust the offset.
Execute the automatic offset adjustment if the torque ripple is too large when compared with
other SERVOPACKs.
The offset does not use a parameter, so it will not change even if the parameter settings are
initialized.
