Re: E-stop relay welds contacts for load dump resistor

Dave: I was thinking about your advice, below and then double checked
Geckodrives documentation for the G320X servo drive. I did most of my
electronics enclosure assembly and wiring last winter so I had to look
over some of my schematics and documentation. Mariss specifically
states in his tech sheet for the G320X:

"IMPORTANT: Never put a switch on the DC side of the power supply!
This will damage, if not destroy, your drive!

I am sure that Mariss is speaking from experience, so this is why my
E-stop circuit is designed the way that Geckodrive specifies. Thanks!

Dan.
