Detailed instruction of parameters
The setting range: 0.00 Hz–P00.03 (max. output
frequency)
This parameter is used to control the internal brake
pipe inside the VFD.
0: Disable
1: Enable
Note: Only applied to internal brake pipe.
Set the starting bus voltage of dynamic brake,
adjust this value properly to brake the load
effectively. The default value changes with voltage
level
Setting range: 200.0–2000.0 V
0: Normal mode
1: The fan keeps running after power on
0x000–0x111
LED ones: PWM mode setting
0: PWM mode 1, 3PH and 2PH modulation
1: PWM mode 2, 3PH modulation
LED tens: Low-speed carrier frequency limiting
mode
0: Reducing the carrier frequency at low speed,
limiting the carrier frequency to 4 kHz when the
machine runs at low speed. This mode is valid only
for the closed-loop vector mode (P00.00=3).
1: No reducing the carrier frequency at low speed
Hundreds place: Dead-zone compensation method
