I do have a few questions: Is there anybody that has tuned Ac fanuc motors (red cap) using the PID. I can make them work, but I don't like just putting any # in and seeing what happens, well I know what happens, the motor jumps off the bench and almost breaks the encoder off. The motors don't hunt or vibrate and run good but sound loud when running, doesn't matter what values I put in, those Fanuc motors usually are as quiet as a mouse when running.
The other problem I'm having is, when I do a sample program just running the motors if I hit feed hold, which is the normal way to halt your program, the motors seem to just slow down and squeak to a stop, then I cycle start and they slowly ramp up to speed and carry on, yet If I stop the program, the motors stop instantly, then I cycle start and they start instantly.
All the machines I have worked on don't have a program stop, they just have a feed hold then you would use the reset if you want to terminate the program, am I missing something.
I must admit, I do like the Mach3, I've been around Fanuc for too long….
