voltage
After setting the original bus voltage to brake the
energy, adjust the voltage appropriately to brake
the load. 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:

Cooling fan
running mode
0: Common running mode
1: Keeps running after being powered on
2: Runs when the inverter ramp frequency is no
less than 0 Hz and the inverter output current is
no less than 10% of the inverter rated current. If
the inverter ramp frequency is 0 Hz and the
inverter output current is less than 10% of the
inverter rated current or the inverter stops
running, the fan stops running within 1 minute.

mode
0: Low-speed carrier frequency limit mode 1, the
carrier frequency will limit to 1k or 2k if it exceeds
2k at low speed
