New controller wiring - charge pump to drop G201X drive power, or ???

[mschoonmaker]

I've recently purchased a CNCDrive AXBB-E controller, and will be wiring it into a Romaxx WD-1 CNC. The existing wiring uses Mach3's Charge Pump circuit in series with the E-stop button to drive a relay which in turn drops power to the G201X drives. I've read elsewhere that dropping power to the drives can be damaging. It would seem that another method might be to use the same approach but instead of dropping drive POWER, to simply drag the drive's DISABLE terminal to ground.

I'd be interested to hear other more experienced users' perspectives, thanks!
