Stall prevention during acceleration (08-00=xxx0b)
Prevents the inverter from faulting (Overcurrent, Motor overload, Inverter overload) when accelerating with heavy
loads.
When the inverter output current reaches the level set in parameter 08-01 minus 15% the acceleration rate starts
to decrease. When the inverter output current reaches the level set in parameter 08-01 the motor stops
accelerating. Refer to figure 4.4.67 for more information.
Notes:
- Reduce stall prevention level during acceleration (08-01) in case the motor stalls (when the motor power is
smaller than the inverter rating.
- The inverter rated output current should be set to 100%.
