RE: [CAD_CAM_EDM_DRO] Help, continuing to burn drives

A few things come to mind right away:

1. Are you using regulated or unregulated power supply? Spikes would be less
of a problem with regulated power supply.
2. Make sure and use fast acting fuses to protect the power junctions on the
Gecko drives.
3. I am sure you must have checked for any possible shorts in the wires from
Gecko to the motor.
4. Can you tell us more about the motor you are using?
5. Are your controller with Gecko drive and your motor grounded properly?
With heating system working in the winter time, you may have a very dry (low
humidity) conditions and hence, static electricity problems.

Good luck.

Subject: [CAD_CAM_EDM_DRO] Help, continuing to burn drives

Hi Guys, My bridgeport retrofit continues to burn Gecko drives. It
happened just a few minutes ago when I powered up the machine and
computer. The powersupply was plugged in but the relay controlling
the powersupply was off. When I hit the button in the software to
turn on the relay the Gecko immediately burned as did the protecting
fuse. It always happens on the y axis when I first start up. It
never seems to happen while running the machine. This is at least the
fourth time this has occurred. Each time I think I have found the
problem but alas, no. The last time was early Feb and then again
last week. A new Gecko was installed thursday. It makes no sense
why the thing would run for a month with no trouble. It think
everything is installed correctly but there must be a powersurge from
the powersupply when the relay first turns on. Is this a possibility
and is there a way to protect from this?

Thanks for any ideas!

Keith Clark
