
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.
