Where to start?
Vintage 1998, Exsisting Grinding Machine acting up. What I know at a glance. 2 Axis Servo, AB 8500 motors, AB 9/Series controller, just looks like a back plane, one Yaskawa Servo Amp, three AB Denso I/O Blocks. Didn't look at HMI, should have, but think it is AB 9/Series CNC type from what I say on AB's web site. The controller looks like it has a fiber link ti I/O blocks.
My question is. Can I get online or view the programs offline? How to communicate with the controller. So far one of the operators says that two programs losse home reference, but one other one works fine. The difference in these programs as discribed operator, is that the wheel dressing routine happens at different times in the run sequence. What works, dress all three wheels them run grinding routine. What doesn't work, dress two wheels run their routine, dress third wheel run that. Position drift or error happens after the first wheels run and before third dressing. The axis that is lossing home reference or gets the drift is the vertical axis, what I would call Z. It's only movement is for dressing and grind depth.
That's enought for now. I must look more closly Monday. Any past experience would be helpful. Thanks
