Stall protection
during
acceleration
If inverter output current exceeds the preset stall
level (PRT- 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 (DRV-19). If the current level causes
deceleration below the preset level while
operating the stall protection function, the motor
resumes acceleration.
