In order to ensure the torque of the VFD when starting, please set appropriate start
frequency. And to build up the magnetic flow when the electric motor is start,
please keep the start frequency for some time and then speed up.
If the frequency reference (frequency source) is lower than start frequency, the
VFD cannot start, and keep in standby mode.
When switching between forward and reverse direction of motor rotation, the hold
time of start frequency will not take effect. The hold time is not included in the speed
up time, but in the running time of simple PLC function.

DC barking before start is usually used to make the electric motor totally stop before
starting.
If the starting mode is DC barking before starting, the VFD will brake in DC current
according to the pre-set DC braking current, and the VFD will begin to run after the
pre-set time of DC braking current. If the pre-set time of DC braking current is 0, the
VFD will start directly without DC braking.
The larger the DC braking current is, the stronger the braking force.
DC braking current before start is a percentage with respect to the rated current of
the VFD.
