If you did not use an identical controller to the original, but used the original display, then that is the cause of your comm error (which has nothing to do with the motor, only the display/controller communications).
You would have to use the identical controller, or you would have to buy a controller/display set that are designed to work with each other.
If the above is not the case, you'll need to provide *complete* details, step by step, on the entire situation starting from before the original failure (to determine the cause of it and be sure the controller is actually the problem, and the only problem) and all parts involved including links to where everything was purchased, and exactly how everything was wired before, and exactly how it is wired now, so we can try to figure out what you need to test and/or replace.
Since your problem is not the same as this thread is for, I moved it to a new thread for you. If you prefer a different thread title, just edit your first post in the thread to change it.
