[Da...] Posted April 26, 2022 Share Posted April 26, 2022 Hi, We have a Zeiss UMC850 machine and over the last few weeks the drives keep tripping out ? I have checked and adjusted the air pressure but it is still happening. See attachments for error messages.Capture.PNGCapture 2.PNG Link to comment Share on other sites More sharing options...
[To...] Posted April 26, 2022 Share Posted April 26, 2022 Have you noticed if the drives kick out while doing a particular move or at same location? Dirty scales will cause the drives to kick out at the same location. Link to comment Share on other sites More sharing options...
[Er...] Posted April 26, 2022 Share Posted April 26, 2022 If the UMC is like the Eclipse, there is a "safety chain" that kicks out the drives. Anything in that chain can kick out the drives, and it is a long list. We would get "mid-air" collisions and the drives randomly kicking out. Turned out a wire in the cable run for the Z axis had an intermittent break. The Zeiss tech diagnosed it by taking the wires loose from the run and manually flexing it at random spots. He found one spot he could flex and it would kick the drives every time. Link to comment Share on other sites More sharing options...
