for reducing external electromagnetic interference.
When the depth of random PWM is set as 0, random PWM is invalid. Various effects can be gained by
adjusting the depth of random PWM.

Start quick current limit function and it can reduce over-current failure at most to ensure the continuous
operation of frequency converter.
If the frequency converter can keep quick current limit state for a long time, the frequency converter may
appear overheat or other damages which are not permitted so Failure Err40 shall be alarmed when the
frequency converter keeps quick current limit for a long time to express that the frequency is overloaded
and it shall stop.
A5-05
Current detection compensation
Default value
5
Set range
0
~
100
If the current detection compensation used for setting frequency converter is set too large, it may cause the
control performance to decrease and generally it does not need to modify.
A5-06
Under-voltage point setting
Default value
100.0%
Set range
60.0%
~
140.0%
It is used for setting the voltage under-voltage failure Err09 of frequency converter and the frequency
converters under various voltage classes correspond to different voltage point, including:
A5-07
SVC optimization mode selection
Default value
1
Set range
0
Not optimized
1
Optimization mode 1
2
Optimization mode 2
Optimization mode 1: It is used under higher linear requirements for torque control.
Optimization mode 2: It is used under the requirements for higher speed stability.
