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 VFD trips.
During the running of the VFD, this function will
detect the output current and compare it with the
limit 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.
