PMDX-424 Source for Gecko 203V Disable Voltage

[broered]

Gecko 203V's have a disable terminal.  Their manual says that you can force winding currents to ZERO by connecting this terminal to the Step/Direction controller's +5V.

I'd like to tie all 4 of the 203V's disable terminals to a single switch, then to 5V, somewhere on the PMDX-424.

(1) can I tie all 4 of the 203V's disable terminals together without causing problems?
(2) what's the best place, on the PMDX-424, to get the 5V from?

thanks

Yes, you can tie the "Disable" input on all of the G203V drivers together.  The 5V to drive the "Disable" input can come from the "L+5V" terminal on J12 or J13.  These connector shares the same ground as the step/direction outputs.**

** NOTE: Well, the "ground" that can appear on the step/dir "com" terminal is not actually ground, but ground through a buffer IC.  So when the step/dir common is set to "ground", it may actually be a 1/10th or two above the "Lgnd" on J12 or J13.  But that is OK as far as the G203V is concerned.

Really pleased with all the technical information I'm getting from PMDX as I work my build.
Thanks again Bob!
