When using this function, if you reset the inverter in the terminal block of loader after a
trip, the motor starts rotating. Be careful of an accident.

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.
