ACS880 Fault: PU Communication (5681 hex), 000 0004 hex
We have around 180 new ACS880 drives in a new Galvanizing Line.
In some drive we have the fault code 5681 - PU Communication. This fault occurs randomly but generally when we order to stop the drive.
At this point, we made:
Check the connections between the power unit and control unit.
Check the power source of control unit.
Update firmware drive to 2.83.
Check parameters.
Even total replacement of one of the drive with the failure.
And the failure still occurs....
I hope you can help us with this failure.
Best regards,
Gustavo M. Villegas.

Hi
directly from ACS880 FW manual:
have you checked how parameter 95.04 is programmed?
Do your drives have 24VDC auxiliary power supply on terminals XPOW1 and XPOW2 or not?
Let us know about the results
