View Full Version : ECAS 20 - Profibus-DP: fault of drive

07-21-2009, 11:41 AM
Any ideas on how to fix a fault of drive? Last time we had this problem on a machine I wasn't around to see how it was fixed by the tech and ended up getting charged a pretty good buck.

The alarm log shows fault on ALL drives and also states that some of the homed axis are on limit switches, which they are not.

Something isn't right here...any help is great.

Is yours one that has the dreaded Yaskawa-Siemens control? Good luck if it does. Lousiest interface between a control and a machine tool that I've ever seen.
