We checked the three pacsci pc800 servo controllers and they all look OK, no red or error lights. VRM amps all look OK. Still haven't found the issue.

We powered up our Advantis machine after leaving off for several months. When we powered it up went to zero it we get an error on the y1 axis during zeroing. Command move home: pattern step 0. The y negative limit is hit during homing, the axis then

I work on a few of these Universal machines before. Check your severos ( I believe their 6 of them ) in the back of the machines all of them should be on. If you see a red light on one of them it's gone bad and that's your Y axis card. It's easy to

Thanks, I do recall reading about loading firmware onto some of the VME cards (VRM axis controllers I believe.) I will review this again. I agree that it seems to be some issue with reading axis position after hitting the home switch. The first thin

Wipe down and clean the 2 Gold strips on Y Axis and the encoder ( located on both sides of the machines covers must be removed ) Probably has dirt happen to someone who had an old universal 2007 that was sitting outside in the open air for a few day

We swapped the Y1 and Y2 pc800 controllers with no change. We swapped out the UIMC III-I cards from another machine with no change. VRM amps all look OK, no errors. The machine moves the head both in the x and y directions during the zeroing attemp

Since you haven't received any useful advise I will throw my 2 cents in. I do not know this machine but in general what you describe is an axis that does not get it's home pulse in time. Many machines will have an in-range sensor that gets flagged
