Need Help!- My 330 is going nuts!

[ktmrider]

A previously well behaved mill is now wigging out. When I turn the power on the servos start moving. Something common to all 3 axis is causing them to just move uncontrollably. Any suggestions what to look at first?

Thanks for the help.

control? Sytem 10, 20, delta 10,20, PC2100?

The contoller is Mach 3 via a KFlop/KAnalog. The contoller is not sending anything to the N360s. Where they used to sit still now makes them take off and buzz around. I wonder if one leg of my phase convertor is a little hotter then the other two by roughly 15 to 20 volts is making the N360s go silly.

Sorry, can't help on home brewed stuff.

System 10 mostly. Its all stock from the drives out. I know the Mach 3 is not sending a signal to move. Something common to all three axis is off.

Check the wiring to your servo drives, there may be a loose or disconnected one.

Ktm Rider....was this issue solved? I have a Y servo motor that started to do something similar to what you are describing.
