Working Principle
- Variable Frequency Speed Regulation: The door controller VF4+ controls the speed of the elevator door motor by changing the frequency and voltage of the power supply, thus achieving the adjustment of the opening and closing speed of the elevator door. When opening the door, the speed of the motor is gradually increased to open the door quickly; when closing the door, the speed of the motor is gradually decreased to close the door slowly, avoiding a large impact force when the door is closed.
- Position Detection: Sensors are used to detect the position information of the elevator door in real time and feed this information back to the door controller. The door controller precisely controls the operation of the motor according to the feedback position information to ensure that the door can accurately stop at the opening and closing positions.
