A5-02
Dead zone compensation mode Default 1
Setting Range
0 No compensation
1 Compensation mode 1
2 Compensation mode 2
Generally, you need not modify this parameter. Try to use a different compensation mode only
when there is special requirement on the output voltage waveform quality or oscillation occurs on
the motor.
For high power AC drive, compensation mode 2 is recommended.
A5-03
Random PWM depth Default 0
Setting Range
0 Random PWM invalid
1–10 Random PWM depth
The setting of random PWM depth can make the shrill motor noise softer and reduce the
electromagnetic interference. If this parameter is set to 0, random PWM is invalid.
A5-04
Rapid current limit Default 1
Setting Range
0 Disabled
1 Enabled
The rapid current limit function can reduce the AC drive's over current faults at maximum,
guaranteeing uninterrupted running of the AC drive.
However, long-time rapid current limit may cause the AC drive to overheat, which is not
allowed. In this case, the AC drive will report Err40, indicating the AC drive is overloaded and
needs to stop.
A5-05
Current detection compensation Default 5
Setting Range 0–100
It is used to set the AC drive current detection compensation. Too large value may lead to
deterioration of control performance. Do not modify it generally.
A5-06
Undervoltage threshold Default 100.0%
Setting Range 60.0%–140.0%
