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
.

04 Rapid current limit
0

Disabled

:
Enabled
1
The rapid current limit function can reduce the AC drive
'
s overcurrent 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
.
Function Code Parameter Name Setting Range Default

05 Current detection compensation 0
–
100 5
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
.

It is used to set the undervoltage threshold of Err09
.
The undervoltage threshold 100
%
of
the AC drive of different voltage classes corresponds to different nominal values
,
as listed in
the following table
