Fig. 8-48: Stall overvoltage prevention level_during deceleration
Excessive low settings of this parameter may not bring a successful
motor deceleration.
E4.03 Stall overcurrent prevention level
Setting range 20.0 % ~ 250.0 % (of rated frequency converter output current)
Minimum unit 0.1 %
Factory default 200.0 %
Used to prevent the motor from stalling due to the heavy load or too short accel-
eration time. This function is always active during acceleration and for running
at constant speed.
During acceleration
● When the output current of the frequency converter is larger than the stall
overcurrent prevention level [E4.03] during acceleration, the output frequen-
cy increasing will be stopped.
● When the current is lower than [E4.03], the acceleration resumes.
This function will lead to longer acceleration time than settings.
