Current limit
action selection
The actual increasing ratio of motor speed is lower
than that 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.

P11.06
Automatic current
limit
During the running of the inverter, it 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.
