P08.30
Frequency
decreasing
ratio in drop
control
The output frequency of the inverter changes as the load.
And it is mainly used to balance the power when several
inverters drive one load.
Setting range:0.00~50.00Hz
0.00Hz
○
P08.32
FDT1 electrical
level detection
value
When the output frequency exceeds the corresponding
frequency of FDT electrical level, the multi-function digital
output terminals will output the signal of “frequency level
detect FDT” until the output frequency decreases to a value
lower than (FDT electrical level—FDT retention detection
value) the corresponding frequency, the signal is invalid.
Below is the waveform diagram:
Setting range of P08.32: 0.00Hz~P00.03
(the Max. frequency)
Setting range of P08.33 and P08.35: 0.0~100.0%
Setting range of P08.34: 0.00Hz~P00.03
(the Max. frequency)
50.00Hz

P08.33
FDT1 retention
detection value
5.0%
○
P08.34
FDT2 electrical
level detection
value
50.00Hz
○
P08.35
FDT2 retention
detection value
5.0%
○
P08.36
Frequency
arrival
detection value
When the output frequency is among the below or above
range of the set frequency, the multi-function digital output
terminal will output the signal of “frequency arrival”, see the
diagram below for detailed information:
The setting range:0.00Hz~P00.03(the Max. frequency)
0.00Hz

P08.37
Energy Braking
enable
This parameter is used to control the internal braking unit.
0:Disabled
1:Enabled
Note: Only applied to internal braking unit.
0

P08.38
Energy braking
threshold
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.
The setting range:200.0~2000.0V
In order to prevent customers set the value is too large, it is
recommended setting range:
Voltage
220V
380V
Range
375~400V
685~750V
220V
voltage:
380.0V
○
380V
voltage:
700.0V
P08.39
Cooling fan
running mode
0:Rated running mode
1:The fan keeps on running after power on
0

P08.40 PWM selection
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
0x01
