It would seem a simple quest...

I need a DC Motor Controller (PWM) to allow me to control a little 24V 775 DC Brushed Spindle Motor via the 0-10V speed signal from a G540. I can't find any! I can find plenty of them with a built in pot - and I have also blown up a couple of them trying to modify them for 0-10V input (via external voltage divider). Surely, they must exist somewhere?

- Control Input: 0-10VDC Analog (as supplied by the G540)
- Power Input: 24VDC
- Motor Output: 24VDC (PWM) ~5A-10A

Any suggestions?
