realize smooth start of rotating motor,suitable for large inertia load to start again when the
instantaneous power failure.
It only applies on the inverter of 7.5kW and above.

Set proper starting frequency can increase the starting torque.The inverter runs from
the starting frequency and after the keeping time of the starting frequency,the inverter will
accelerate to the aimed frequency during the ACC time.If the reference frequency is less
than starting frequency,the inverter will be at stand-by status.The starting frequency
could be less than the lower frequency limits.The starting frequency takes no effect during
FWD/REV switching.

During the DC braking before F1.03,the increased current is the percentage to the
rated current of the inverter.
DC braking is invalid when F1.04 is set to be 0.
The bigger the DC braking current,the greater the braking torques.
