Name Description Default Modify
frequency at P11.02, to make the inverter
generate power again. The returning power can
maintain the bus voltage to ensure a rated
running of the inverter
until the recovery of
power.

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
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
