4C will not home | 12 January, 2009

A customer of mine has a Quad 4C that will not home in the X. It used to have the problem in the Y then they changed the cards and now that machine will not home in the X when powered up. Anybody have any ideas. I think I know what the problem is, but I wanted to see if anyone else has seen this before?

I am assuming that the card that was changed was the motor driver card. Did they change the card with a known good board or just swap the X and Y cards. If they swapped cards it appears that the card that is now in the X motor slot is bad. Open the access panel to the motor controller cards and check if any of the cards have the red LED indicators on. Red indicates a bad card or if all have red indicators on there is an interlock switch open. Check the fuse on the suspect motor driver card.

They claim that they changed both cards, but I would only imagine this happened myself.

They also need to make sure that the switch settings are correct when changing cards. Each motor driver card has a different switch configuration depending on which slot it is installed in.

They claim that they confirmed this with PPM. I plan to be at this site next week so I cna have a look for myself. I thought also a potential encoder until they said the problem went from y to x. I have replaced encoders that cause this problem in the past.
