the VFD needs to be used with derating. Normally 5%
derating of VFD current for every 1kHz increasing of
carrier frequency.
Notice:
1: Select different carrier frequency method via
function code F0.22.
F1 Basic Running Parameter
F1.00
Start mode
0~2
0
0: start at start frequency
Start with start frequency (F1.01) and its
corresponding retention time (F1.02) that has been
set.
1: DC braking and start at start frequency
DC brake (F1.03, F1.04) first, then start in method 0.
2: start with speed tracking
When power on after power off, if it meets the
starting condition, after a period of time defied by
FC.15, the VFD will start automatically in speed
tracking method.

Start frequency is the initial frequency when the VFD
starts, as fs showed in the following figure. For some
system with relatively big starting torque, a reasonably
set start frequency can solve effectively the hard
starting problem. The retention time of start
frequency is the time VFD stays in the start frequency
value during starting stage, as t1 showed in the
following figure.
Figure F1-1 Start Frequency
Notice:
1.Start frequency is not effective by lower limit
frequency. Jog frequency is not effective by lower limit
frequency but is restricted by start frequency.
2.When F0.18=1 (high frequency mode), start
frequency has a upper limit of 500.0Hz.
