A noisy PWM signal to the speed controller might do this, but there's no obvious way for that to happen. Unless maybe your Digital Sidecar doesn't have a good 12V power feed, and it's stealing current from the Digital I/O module's output? It's always worth checking to make sure the power cord is plugged in and providing power.
