during
acceleration
If inverter output current exceeds the preset stall
level (Pr. 52, 54, 56, 58) during acceleration, the
motor stops accelerating and starts decelerating. If
current level stays above the stall level, the motor
decelerates to the start frequency (dr.19). If the
current level causes deceleration below the preset
level while operating the stall protection function,
the motor resumes acceleration.
