Rexroth Frequency Converter EFC 3600
Fig.8-43: Stall overvoltage prevention level_during deceleration
Too low settings of this parameter may not bring a successful motor decel‐
eration.
E4.03 Stall overcurrent prevention level
Setting range 20.0 % ~ 250.0 % (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 acceleration
time. This function is always available during acceleration and at constant speed.
During acceleration
● When the output current of the frequency converter is larger than the stall overcur‐
rent prevention level [E4.03] during acceleration, the output frequency increasing will
be stopped.
● When the current is lower than [E4.03], the acceleration resumes.
This function action will lead to longer acceleration time than settings.
