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 the VFD
trips.

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.
