Steve,
When I click the 'Spindle CW F5' button in Mach3 the spindle at first does nothing. It isn't until I also hit the 'reset' button that it comes on.
It revs a crazy high speed and says 833% on the spindle override. I can tweak its settings and get the number down and get the spindle turning at a slower speed but the seems no method to its madness. Sometimes I think it even goes backwards. Even when I uncheck 'reversing'.
The biggest problem I see is when I start a program that turn on the spindle it faults my drives. That looks to be an 'over current' error due to ramping down after a rapid. But does not do that when the spindle is disabled. Also appears not to do it as much if I mess with setting and the spindle turns counter-clockwise.
Understanding that a lot my problems probably has to do with my overall motor-tuning and gearing, but what I still don't understand is what my spindle is.
I have wired it as in the last picture diagram and set it up specifically according to your application notes AN002. But is that a correct starting point for me?
Is it possible that I have too many wires connected?
Is my 10hp, 3phase 24000 rpm spindle/controller considered a PWM, PID, STEP/DIR, RUN/DIRECTION, FORWARD/REVERSE, VSD, VSF, VFD ????
Given my setup, are there more real world numbers and setting that I should start with other than what is called out in the AN002 that you could recommend?
Any help would be GREATLY appreciated!
