Rapid Current Limiting
Enable
0: Disable
1: Enable
1
○
Use rapid current limiting function, can maximum limit reduce inverter appear overcurrent fault,
ensure the inverter uninterrupted running.
If the frequency inverter in rapid current limiting condition for a long time, frequency inverter could
overheat and other damage, this situation is not allowed, so the frequency inverter will alarm fault Err.
38 when for a long time fast current limiting, said inverter overload and need to stop.
A1-07
Current Detection
Compensation
0~100
5
○
Used to set the current detection compensation of inverter, set too large may lead to a decrease in
control performance.
Generally do not need to modify.
A1-08
SVC Optimize Mode
Selection
0: Optimize 0
1: Optimize 1
2: Optimize 2
1
◎
Optimize mode 1: used when have higher torque control linearity requirements.
Optimize mode 2: used when have high speed stability requirement.
A1-09
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.
A1-10
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.
A1-12

A1-13
Low Frequency Carrier
Limit Mode
0: Limit mode 1
1: Limit mode 2
2: Not Limit

○
Optimization parameter, generally do not need to modify.
