First of all, I have been reading MANY posts on this forum that have helped me a lot; THANKS!

A friend gave me an Excel 510 with Fanuc 0m control, that of course, had dead memory batteries. I bought parameters from the factory and got things running superficially.

I had to adjust the tool change height and spindle orientation, but I can perform a tool change using the manual switch on the control panel. (not in a program, yet.) Other than this, most aspects have been working fine.

I am writing today because any program I run will start the spindle, but the program freezes at that point. If I take the M03 line out of the program, and start the spindle using MDI, I can run the program just fine.

I suspect that the controller might be waiting for a feedback signal that indicates proper speed before proceeding, but I:
- Haven't yet put a tach on the spindle
- Don't know which diagnostic point to read to check the speed sensor
- Don't know where the adjustment is, should I need it

Any insights will be greatly appreciated.
