A7C1 warning on ACS580 drive 2.2 Kw.
Hi Team,
A7C1 warning on ACS580 drive 2.2 Kw.
Three frequency drives connected with ethernet protocol of Siemens PLC 1200.
Checked the parameters 50,51, 52 ok.
Replaced the ethernet cables but the same.
We have same two machine when we interchange drive from effected panel to normal than same problem turns to that panel.
we found that when A7C1 alarm coming the IP address of drive turns to zero in the drive parameters.
192.168.1.10 ……to 0.0.0.0
Please advices us what should be the route cause.

Hi
mine is just a hypothesis .... after programming the drive Ip addresses, did you save with parameter 51.27?
Are there any addresses coming from the PLC that rewrite the parameters where the IP address data are stored?
In order to express a more detailed opinion, I should have an overview of the PLC as well as the drive ...
