Detailed instruction of parameters
This parameter is used to control the internal braking
unit.
0: Disabled
1: Enabled
Note: Only applied to internal braking unit.
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:
Voltage
Range
0: Rated running mode
1: The fan keeps on running after power on
0x00–0x21
LED ones: PWM mode selection
0: PWM mode 1, three-phase modulation and
two-modulation
1: PWM mode 2, three-phase modulation
LED tens: 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
