we are running geckodrive servo 6320 on a plasma cutter. I don't think we have ever run 6 continuous yet, but as for overheating not sure how to check that other than put my hand on them and none have ever been hot. the problem has mostly been with the "y" axis. We will be running through a pattern then in the exact same spot every time the gecko will fault. It doesn't stop it just re-zoroes at that point and continues cutting the part.
Thanks for the info
Faulting on a G320 is the result of either over-current, or excessive following error.
Do you know how the current limit is set? If it is set low, it could be your machine has gotten tighter over time, so the motors have to work harder, hence draw more current. You could try turning the current limit up higher, and see if the problem goes away.
If the fault is due to following error, that suggests the Gain/Damping tuning on the Geckos is incorrect, and should be re-done. The fact that the fault occurs at the same point in the program every time strongly suggests this is the problem.
