during motor constant operation.
If the output current exceeds the setting specified in Pr.06-04 when the drive is operating, the
drive will decrease its output frequency (according to Pr.06-05) to prevent the motor stall. If the
output current is lower than the setting specified in Pr.06-04, the drive will accelerate (according
to Pr.06-05) again to catch up with the set frequency command value.

Accel./Decel. Time Selection of Stall Prevention at Constant Speed
Factory Setting: 0
Settings 0: by current accel/decel time
1: by the 1st accel/decel time
2: by the 2nd accel/decel time
3: by the 3rd accel/decel time
4: by the 4th accel/decel time
5: by auto accel/decel
It is used to set the accel./decel. time selection when stall prevention occurs at constant speed.
