Most of this emotion is the limit switch problem, it is possible that the limit switch installation location is not accurate, or is damaged. When the door in place, the limit switch will issue a stop signal, cut off the motor power supply. At this time, if the door does not immediately stop, continue to move forward under the inertia, it may pass through the limit trip switch, the trip switch from the parking signal state is not converted to stop the signal state, but this is the door or closed The So the controller in the control program I do not know how to control. This is a defect in the design of the controller and can not cope with special circumstances. The best solution is to use mechanical limit switches and relays to form a new control system.
