Dead Zone Time
Adjustment
100%~200%
150%
○
Aimed at 1140V voltage level setting.
Adjustment this value can improve the effective utilization of voltage, adjustment is too small easy to
cause system unstable.
Don't suggest the user to change.

Droop Control
0.00Hz~10.00Hz
0.00Hz
○
This function is commonly used for load distribution when multi motors are by drive the same load.
Droop control refers to with the increase of load, make the inverter output frequency drops, so when
multi motors drive the same load, the motor output frequency of the load drop more, thus can reduce
the load of the motor, realize the load distribution of multi motors.
This parameter refers to the frequency inverter in the rated output load, the decline in value of the
output frequency.
A1-11
Cooling Fan Control
0: Fan operation in runtime
1: Fan is always running
0
○
Used to select the action mode of cooling fan, selection for 0, the fan running when the inverter in
running state or if the radiator temperature is higher than 40 degrees in stop state, and doesn't work
when radiator less than 40 degrees in stop state.
When selection for 1, the fan operation after power on.

Low Frequency Carrier
Limit Mode
0: Limit mode 1
1: Limit mode 2
2: Not Limit
0
○
To limit the carrier frequency when low frequency.

FVC Optimum Mode
Selection
0: Optimize mode 0
1: Optimize mode 1
2: Optimize mode 2
1
◎
Optimize mode 1: used when have higher torque control linearity requirements.
Optimize mode 2: used when have high speed stability requirement.

Output Phase Loss
Judgement Benchmark
0 : Running frequency
1 : Given frequency of slop
0
○
In order to prevent the false alarm phase, the output phase is not detected when the frequency is
quite low. But in order to avoid operating frequencies in the limiting case is suppressed to very low
times could not reporte phase loss, the determine benchmark will changed for the slope given
frequency.
A2, 3, 4 Motor 2 Parameter Function Group
VD530 can switch run between the two motors, two motor nameplate parameters can be set
respectively, can selection for motor parameter tuning, can respectively selection V/F control and
vector control, encoder related parameters can be set respectively, can set the related parameters of
the V/F control or vector control performance separately.
Specific parameter regulation refer to the related parameters of motor 1.
