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
inverter trips.
During the running of the inverter, this function
will detect the output current and compare it with
the limit level defined in P11.06. If it exceeds the
level, the inverter will run at stable frequency in
accelerated running, or the inverter 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 inverter will accelerate to run.
Setting range of P11.05:
0: current limit invalid
1: current limit valid
2: current limit is invalid during constant speed
Setting range of P11.05: 0x00–0x12
Setting range of P11.06: 50.0–200.0% (relative
to the percentage of rated current of the inverter)
Setting range of P11.07: 0.00–50.00Hz/s
The output current of the inverter or the motor is
above P11.09 and the lasting time is beyond
P11.10, overload pre-alarm will be output.
