Description
After setting the original bus voltage of energy
braking, you can
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:
Voltage
Range 375–400V
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.

Ones place: PWM mode selection
0: PWM mode 1, three-phase modulation and
two-modulation
1: PWM mode 2, three-phase modulation
Tens place: low-speed carrier frequency limit
mode
0: Low-speed carrier frequency limit mode 1, the
carrier frequency will limit to 2k if it exceeds 2k
at low speed
1: Low-speed carrier frequency limit mode 2, the
carrier frequency will limit to 4k if it exceeds 4k
at low speed
2: No limit
