0 volt grounding and wierd random servo faulting
« on: February 12, 2012, 08:41:51 PM »
Hi, Ive been getting some really random faulting on my g320's on all axis.All 3 are are identical and they are all tuned really nicely,theres bags of power and it makes no differance if I up the multiplier or gain settings or error limit.
I have caps on the power feed to the heds encoders as recomended by gecko,and plain twin core  ,I do have shielded  (earthed controller end) a&b lines the only thing I havnt done is connect the 0v on the computer to the 0v on the servo power supply or specifically to earth,could this be the problem? the machine runs great and dosnt miss steps, its not running flat out and I have no reason to doubt the step pulse.just these totally random intermittant trips - weird!
cheers Tony.

well I linked everything up in a star config and that seems to have sorted it

Star config is always recommended.

Cheers
