Technical advantages:
End buffer technology: Based on the constant torque characteris-tics of the motor system, the door body runs extremely smoothlyand solves the noise problem of the door body during operation. Atthe same time, the end buffer technology protects the reducer andbrake pads more effectively. In fact, it is necessary to digitallyadjust different speeds,fast-slow-stop dynamic changesthroughout the process, reduce the impact of various parts in themotion stop, especially the protection of the deceleration mecha-nism is the most prominent.
Reversal noise reduction technology: Whenever it encountersresistance and bounces during the descent process, the programin the driver will quickly stop and rise through the state of the cur-rent loop, position loop, and speed loop.In the case of controlwithout shake and noise, the inertial impact will not More than3mm distance.
Anti-collision recovery technology structure: In the event of an ac-cidental impact, the door curtain can be derailed and automaticallyreset during the ascent. The whole process does not requiremanual repair and control unit reset.
Safety technology: lt only takes 10 milliseconds for the motorsystem to start and stop between 0-2000 revolutions, which is themost sensitive of all door opener systems at present.
Infrared safety protection electric eye: There are infrared countersensor on both sides of the door frame, and there is an obiectunder the fast door to keep the door open; when the door body islowered, there is an object passing underneath, the door body willopen to the most open position, and wait until there is no obstaclebelow The delay drops.
