Powerflex 755 with CompactLogix

[Eddie Veldkamp 0]

We have at the site an installation to move a deck. Therefore we need to control 8 drives at the same time. We have a compactlogix L30ER and in total 8 Powerfelx 755 drives. In our software we have 1 master drive and we copy the control data to each drive. We use the status data off all drive to check if everything worked ok. 3 of the 4 times everything works fine. We are able to home, to jog and to move to a position. But sometimes 1 or 2 of the drives will not move. At this point we have no clue what causes this strange problems. Does anyone have an idea? The compactlogix L30ER communicates trough Ethernet with the drives, and the drive cabinet is 30 meters from the controller cabinet.

are you indicating that the Status indicates the drives are active and running, but in fact they are not? bob
