P11.05
Current limit
action selection
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
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 ACC 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
