Section V. Parameter Function Table
A5.03 Random PWM depth
Random PWM invalid
0
0
☆
PWM carrier frequency random depth
1~10
Set the random PWM, monotonous and harsh electromagnetic noise can be changed to the
heterogeneous and soft, the external electromagnetic interference can be effectively reduced. 0
indicates that the PWM is invalid. Different random PWM depth represents different regulation effect.
A5.04
Rapid current-limiting enable
Invalid 0
1
☆
Valid 1
Enable the rapid current-limiting function so as to minimize inverter overcurrent protection fault and
make the inverter work normally.
If the inverter long time continuous staying in rapid current-limiting state, it may occur overheating
fault, which is not allowed during operation. Fault alarm of long time rapid current -limiting is 40= Err40 ,
which refers to inverter overload and necessary stop.
A5.05
Current detection
compensation
0~100
5 ☆
It is used to set inverter current detection compensation. Excessive setting may lead to decrease of
control performance.Generally do not need to be modified.
A5.06
Under-voltage point setup
60.0%~140.0%
100.0% ☆
A5.06 is used to set value of inverter under-voltage fault 9= E.LU. Different voltage level of 100.0%
corresponds to different voltage point,respectively

：
Optimization mode 1
It is used when there is high torque control linearity requirements.
2
：
Optimization mode 2
It is used when there is high speed stability requirement.
A5.08
Dead zone time adjustment
100%~200%
150%
☆
This parameter is set according to 1140V voltage level. By adjusting the value can improve the
voltage effective use rate. Users are not suggested to modify.
A5.09 Overvoltage point setup 200.0V~2500.0V 810.0V
☆
A5.09 is overvoltage point set through software, which is not related to hardware overvoltage point.
