Dear Lvyuan User: Hello! This is not entirely caused by the controller, you said after the power is turned on the motor is very difficult to turn off after the loose, it is because the motor inside the line (thick yellow, green, blue three Line) short circuit, touch line may cause such a situation! The It is recommended to go to the local sale
It may be the brake level is not right, in the brake state. Power tube is broken, there will be no resistance to power! Of course, may also be in a state of anti-theft (anti-theft level is not right) directly to the maintenance point!
They will change the power tube, there is a certain level. Upstairs several questions to complicate the problem, with the brake level or anti-theft and the like did not matter, or control system problems. "Do not add the door motor is stuck plus the door if the motor will shake," you describe the stuck motor should be caused by the lack of phase. Try to solve the problem from the point of view. If you can guarantee that you change the power tube no problem, indicating that the controller is not just the power tube is broken. How about the motor Hall? Do you want to fix the car? Still want to fix the controller ah? If it is the former, do not waste time. Since their own to solve such a professional problem, the controller should also be clear the price, the new get, save time to do anything else.
