The heads in the middle of production stop and this error appears. We already checked the readers, linear encoders and changed the UIMC cards and found no errors, apparently all these revised parts are working. Can anyone help us where else can we c

Hi Spoiltforchoice Thanks for the comment. With the line encoder readers that the machine brings, we performed a positioning reading check, which showed us the increase or decrease in the path that the heads make, with which we conclude that it is re

I don't have one of these machines, but what kind of checks are you able to do on the linear encoders? On our Essemtec there is a dedicated diagnostic utility that gives you a plot of the encoder readout showing both the raw readout as a sort of roun

To me, it sounds like your axis servo is losing steps. Can you get through the calibration steps? Hanwha is who we use for service. I'd say call them if you don't want to just throw parts at it.

Broken wire connecting to the encoder on your servo, or anyware else in the feedback loop?, bent up encoder? sarason

Hello all, I was looking at a Samsung SM421-f component placing machine and it's throwing up an error that was not described in the troubleshooting guide. Anytime I try to move the camera or home it the machine stops and the screen says that a skew e

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

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.

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
