7.13 Adjusting the Motor Current Detection Signal Offset
7.13.1 Overview
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.
7.13.2 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.
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.
Always check the following before you automatically adjust the motor current detection
signal offset.
n The parameters must not be write prohibited.
n The servo must be in ready status.
n The servo must be OFF.
The following table lists the tools that you can use to automatically adjust the offset.
