UH-OH!! Swing motor problems

[9W Monighan]

That's funny, I have similar problems with my swing motor only it goes real smooth one way and sort of glitchy and noisy the other. I had problems at Cabin Fever briefly with it not working at all but I'm pretty sure we were experiencing a brown out in the building because one of the CNC vendors had problems with his mill almost crashing the table. I've been fooling around with my motor drive settings (Dead Band,IR Comp. Response) Another thing happening is my swing won't stay centered from time to time and if I re bind the DX7 again that fixes it for a while. I've never tried putting capacitors on the motors like the lower voltage ones everybody uses because I'm running 90VDC motors and I don't know what uF capacitor to use. A week ago I bought a used line conditioner voltage regulator and we'll see if that takes care of possible voltage drops.

I know nothing about 90V motors but the capacitors work well on the 6&12V motors. But if you have glitching there is probably some kind of electrical noise somewhere. I have heard that the 2.4 radios are better about this. I am using the 2.4 on my truck and it works great even without an antennae but the shovel is on the old 27mghz band. If this problem continues I will be changing radios.
