im sure you have a speed pick up fault, check the magnet in the front roller pulley if that is in place you will probabley have to buy a new switch, try relocating the switch first tho it may be that the distance between the switch and the magnet is to great

im also getting the same error, connected the motor with a battery so it is working. Im not sure what it could be. Did you have any luck with yours?
