A5-04 Fast current limit
0: Disabled
1: 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
A5-05 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.
Function Code Parameter Name Setting Range Default
A5-06

60.0%–140.0% 100.0%
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.
