P11.05
Current limit
action
The actual increasing ratio is less than the ratio
of output frequency because of the big load
during accelerated running. It is necessary to
take measures to avoid overcurrent fault and the
VFD trips.
During the running of the VFD, this function will
detect the output current and compare it with the
limit level defined in P11.06. If it exceeds the
level, the VFD will run at stable frequency in
accelerated running, or the VFD will derate to run
during the constant running. If it exceeds the
level continuously, the output frequency will keep
on decreasing to the lower limit. If the output
current is detected to be lower than the limit
level, the VFD will accelerate to run.
