I'm setting up a product for the first time on my GSM after I completed debugging some other issues. The previous owners had the PWC axis disabled and the axis motor disconnected, so I re-connected it and enabled it and now it homes and moves. When I

RESOLVED I adjusted the "Minimum Board Width" in the Board Handling Configuration to resolve this issue. I set the lane width to a larger value which did not hit the front limit and measured the difference between the actual lane width and the set l

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

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

On the HP Servo panel there are LED's that indicate state of limit switches - so you can see if the problem is in the switch or somewhere else. Did you check it?

Try cleaning the linear encoder reader. I've had dust build up on two of my machines resulting in failure to calibrate. Blowing out the reader heads with gentle compressed air resolved it.

Have you reviewed the wiring diagrams and checked voltages at the input card? Maybe you have a damaged IO card or broken cable.

Tom, Its not the scale but the switch itself because while zeroing, if you activate front limit switch for Y axis, Beam should travel back to look for home pulse. It looks like switch signal does not reach to the system.It is really hard to trace the

I have GSM1 (OS/2) machine and it does not zero. The Y axis comes to all the way front to hard stop. I replaced the limit switch before the hard stop and can not find any way to test the signal from limit switch in diagnostic. I like to replace the c
