I am having trouble getting my Gecko 320's and US Digital E5 encoders working togther. When I first turn on the drives the fault lights are on and after a few seconds they turn off and the drives start cycling. The motors will turn for a few seconds then stop and then restart. After a few cycles the fault lights will light again and the entire process starts over. If I unplug the encoders the motors will run at top speed with no problems. I am new to this and am really not sure what to do next?

Any ideas?
