P11.05
Current limit
action
The actual increasing ratio is less than the
ratio of output frequency because of the big
load during ACC 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 ACC 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.
