OFF and ON again.
Caution
Be careful with this function, which causes the motor to rotate as soon as the power is
supplied.

If you set BAS-08 at Max Freq, you can accelerate or decelerate at an equal slope on
the basis of the maximum frequency regardless of the operating frequency.
The acceleration time set in DRV-03 is the time it takes the frequency to reach the
maximum value from 0 Hz and the deceleration time of 04 is the time it takes the
frequency to stop at 0 Hz from the maximum frequency.
E.g.) If you set the maximum frequency at 60.00 Hz, Acc/Dec time at 5 seconds and
operating frequency at 30 Hz, the time required is 2.5 seconds.
