Encoder and Motor working independently, but not together.

Hi,

I have motor, motor control board and optical encoder being operated through a myRIO. I have the encoder configured to read in RPM on LabVIEW and I am using a digital potentiometer to change the speed of the motor through the PC.

My problem is that the motor will work as normal when the encoder is not powered on but when the encoder is powered on, the motor will not work. The encoder will work with or without the motor on.

I have a attached a pair of photos (digital pot missing from photo).

Thanks.

It would seem it is a software issue.
The encoder normally only affects the motor through software feedback. loop.?

Also remotely possible its a power issue causing the processor to bomb out.
Check your connections and if possible take all grounds to one point.
