Gecko g540 ground pin burned out
Hi I've been running a gecko g540 for almost two years now and just last weekend I couldn't get a red light on it much less green. After a bit of probing around I found the the circuit board ground and my ground wires have no continuity. The green pin tray plastic has a small amount of brown colouration around the ground pin. Has anyone else had this problem? Something obviously burned out between the terminal and the circuit board. Any ideas what the cause would be? I have a surge protector on the setup so I doubt it would be surges. Obviously there was a lot of current in there at some point. Also any ideas on how I could fix the screw terminal so I don't have to solder a wire directly to the gecko?

Re: Gecko g540 ground pin burned out
its the first I have read of a G540 having burnt connectors but
Phoenix Contact connectors burning up are found on a number of threads
like this on a Tormach machine's Leadshine 3ND883 or Tormach driver 31234
examples of burnt connector
Attachment 422306
Attachment 422304
Attachment 422308
the problem can be found with any product using this connector
see post 13

one possible solution if you don't send the G540 back to Geckodrive could be to solder a wire directly to the board

I've also never heard of this on a G540, but I've seen a handful of posts showing it on other Gecko drives.
Re: Gecko g540 ground pin burned out
In addition to the ground/0V pin 12 how does the +18V to 50V supply pin 11 look ?
pins 1 to 10 pass a low current and should be OK
the only other high current connections are the 9 way D-type sockets for the motor connections
its important the supplied 9 pin plugs are used
most D-type plugs found online are low current connectors and will over heat
for example a 3A ebay connector

one 5A connector I found from RS components

There must be over current draw to cause this to happen or there G540 needs better connectors
Re: Gecko g540 ground pin burned out
Just a thought. Have you checked the G540 onboard fuse?

Re: Gecko g540 ground pin burned out
The most likely cause of a burned connector on the GND pin is a loose connection. The increased resistance from an incomplete connection on the header can lead to heating on the connector. I'd recommend sending the G540 back for evaluation and repair so we can check if anything else has been damaged.
