DenisMor Posts: 344 Rating: (50)	There is no communication between the CU320 and drive 3 & 4. The simplest cause would be a DriveCliQ cable between drive 2 & 3 came loose. Check to make sure it is plugged in good. Second problem could be bad DriveCliQ cable. Replace with a different one. Last possibility is bad Drive 3 motor module: no longer communicates on DriveCliQ. Start with the simplest solution and work your way up.

jagathselvan Posts: 1 Rating: (0)	Hello experts , The same problem I’m facing in my plant, CU 320 is connected to 4 drive S-120 motor modules; it is connected separately to the Motor module from the Cu320 viadrive CLIQ cable, after changing the new drive CLIQ cable the fault is not rectified yet. Whether I have to change any of the drive parameter in STARTER if I’m using different ports in the drive motor module…?

Go to the CU in Starter an open the Topologyview. Change the DQ Wirings in the Topologyview an Download the new topology. Regards Christoph
