Stall Prevention Factor 1

Program ⇒ Protection ⇒ Stall
This parameter is to be adjusted in the event that the motor stalls when operated
above the base frequency.
If a momentary heavy load occurs the motor may stall before the load current
reaches the stall prevention level setting of F601.
A drop in the supply voltage may cause fluctuations of the load current or may
cause motor vibration. A gradual adjustment of this parameter may alleviate
this condition.
Start with a setting of 85 at these parameters and gradually adjust them from
there one at a time until the desired results are produced.
Adjustments to this parameter may increase the load current of the motor and
subsequently warrant an adjustment at the Motor Overload Protection Level
setting.
