4525 spindle control issue
We had an issue where by our monitor stopped working
Once fixed we now have an issue where when turning the spindle speed pot down it gets to a point where the spindle stops and runs in opposite direction
We also cannot perform a tool change as the spindle will not stop to allow locking
We have had the machine since 2011 and other than a few valves and belts we have had a great run
Any help would be greatly appreciated
Kind regards

It would depend on your spindle drive. When a spindle drive goes in wrong direction after parts changes, it might need to be "Auto Tuned" The Fadal Maintenance manual will guide you through the autotuning procedure. This will calibrate the Spindle card's signal offset.... I would do this first. Then once that is resolved. you might need to then adjust the SPINDLE ORIENTATION FACTOR, in SETP. That changes the orientation speed. But first do the auto tuning to correct that issue first.
