7.2.11. Adjusting the Motor Current Detection Offset
Motor current detection offset adjustment is performed at Yaskawa before
shipping. Normally, the user does not need to perform this adjustment.
Make this adjustment only if highly accurate adjustment is required to
reduce torque ripple caused by current offset.
CAUTION
• If this function, particularly manual adjustment, is executed carelessly, it
may degrade the performance of the servo drive.
The following sections describe automatic and manual adjustment of the
current detection offset.
„ Automatic Adjustment of the Motor Current Detection
Offset
IMPORTANT
• Automatic adjustment is possible only with power supply to the main
circuits ON and with the servo OFF.
Use the following procedure to perform automatic adjustment of the
current detection offset.
