Setting range: 0.00Hz–P00.03 (Max. frequency)
This parameter is used to control the enabling of
the internal braking pipe inside the VFD.
0: Disable
1: Enable
Note: This function is only applicable to the
internal braking pipe.
Set the initial bus voltage for dynamic braking.
This value can be adjusted to perform valid
braking on a load. The factory setting changes
with the voltage class.
Setting range: 200.0–2000.0V
To prevent customers from setting a value that is
too large, the following setting ranges are
recommended:
Voltage 380V
Range 685–750V 860–950V 1080–1180V
0: Normal mode
1: The fan keeps running after being powered 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
