Stall prevention during acceleration (08-00=xxx0b)
(1) Prevents the inverter from faulting (Overcurrent, Motor overload, Inverter overload) when accelerating
with heavy loads.
(2) 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.
(3) Reduce stall prevention level during acceleration (08-01) in case the motor stalls (when the motor
power is smaller than the inverter rating.
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 Fig.4.3.57 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%.
