P11.05
Current limit

selection
The actual increasing ratio of motor speed is lower
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 VFD
tripping.

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