Adjust the offset amount by 10 in the direction that
the torque ripple is reduced.
Adjustment range: -512 to +511
(ZADJIV: Offset value of phase-V current)
Repeat the operations of steps 4 to 6 (phase-U and-V alternately) until adjusting the offset amounts both for

Then, perform the same operation by adjusting by smaller amount.
