5.
Click the Manual Adjustment Tab in the Adjust the Motor Current Detection Signal Off-
sets Dialog Box.
6. Set the Channel Box in the Motor Current Detection Offset Area to U-phase.
7. Use the +1 and -1 Buttons to adjust the offset for phase U.
Change the offset by about 10 in the direction that reduces the torque ripple.
Adjustment range: -512 to +511
8. Set the Channel Box in the Motor Current Detection Offset Area to V-phase.
9. Use the +1 and -1 Buttons to adjust the offset for phase V.
Change the offset by about 10 in the direction that reduces the torque ripple.
10. Repeat steps 6 to 9 until the torque ripple cannot be decreased any further regardless of
whether you increase or decrease the offsets.
11. Reduce the amount by which you change the offsets each time and repeat steps 6 to 9.
This concludes the procedure to manually adjust the motor current detection signal offset.
