Re: Help- Motors running when they shouldn't be

Concur with Mark on controller calibration being the most likely issue.

It could also be a faulty connection on the PWM line that intermittently gives pulses in the drive speed range; less likely.

Also, check to see if the controller tries to run the motor when the PWM is disconnected. That would be sign of a problem inside the controller.

Another thing you can try is to switch the left and right PWM wires at the RIO end and see if the problem follows the port or the wire/controller/motor system. If it switches, you have some sort of problem in software or the RIO. If it stays with the same motor, it's somewhere on the hardware side of that connection.
