Re: Motor Controller Problems

Our problem is now solved. Thank you very much dee7s for your recommendations.

The tip to check the robot signal light from the DSC got us on the right track. The light would function when plugged directly to 12v power, but would not function when plugged into the sidecar. The DSC did however have all of its status lights on and was receiving power correctly.

It was discovered that our 9403 digital IO module was defective. After swapping a new module into our cRIO, the RSL LED began to blink and the PWM signals became active. I can't believe our 9403 module went bad, but it's true. We now have working motors with a joystick!
