voltage
After setting the original bus voltage of energy
braking, you can adjust the voltage to
implement load braking. The factory changes
with the voltage level.
Setting range: 200.0
–2000.0V
In order to prevent customers set the value is
too large, it is recommended setting range:

mode
0: Rated running mode
1: The fan keeps running after being powered
on
2: The fan runs when the VFD ramp frequency
is no less than 0Hz, and the VFD output current
is no less than 10% of the VFD rated current. If
the VFD ramp frequency is 0Hz and the VFD
output current is less than 10% of the VFD rated
current or the VFD stops running, the fan stops
running whithin 1 minute.
