I am trying to control 4 DC motors (14.4 volt, about 10amp at peak) through 4 Reversible motor controller 24Vdc 15A like this one http://uk.rs-online.com/web/p/dc-motor-controllers/3639601/.
The Arduino will be controlled through Max/MSP’s Maxuino, there I will be able to control every digital pin and set them on High or Low etc.
The way I was going to do this is by wiring Arduino to the Ffwd Rev and H, S, L to control the speed.
So far I have had experience in wiring normal small DC motors controlled via Arduino or Hbridge and I haven’t seen the Ffwd and Rev controls, I was thinking about supplying PWM values through Max and in so control the speed, I am guessing the HSL is confusing me a bit.
Could anyone recommend how should I wire the Arduino to a single controller?
This would surely put me in the right direction in order to learn how to control the others.
Please let me know if you need more details or info, I am attaching one image of the controller, obviously I don’t want to blow anything up and will keep the power of the Arduino separated from that of the the Motor and external Power Supplier.
Should I ground the Arduino too?
Many thanks in advance.
