Precisely control the door speed: By changing the power supply frequency of the motor, the opening and closing speed of the elevator door can be precisely adjusted. When opening the door, the door can be opened quickly and smoothly to improve the use efficiency; when closing the door, the door can be opened quickly and then slowly, which not only ensures the closing efficiency, but also avoids the risk of collision caused by closing the door too quickly, ensuring the safety of passengers and items.
Soft start and soft stop: Provide soft start function for the door machine motor to avoid current shock at startup, reduce wear on motor and mechanical parts, and extend the service life of the equipment. Similarly, soft stop is achieved when the door is closed, so that the door stops gently in the closed position, reduces the closing noise, and improves the riding experience.
Torque control: It can automatically adjust the output torque according to the load of the door. When the door encounters resistance, such as clamping foreign objects, the inverter can detect the abnormality and reduce the closing torque in time to prevent people or objects from being clamped, and enhance the safety and reliability of the door machine system.
Position control: Cooperate with the position sensor in the door machine system to accurately control the opening and closing position of the door. Ensure that the door is fully opened to the set position, providing passengers with sufficient space for entry and exit, and at the same time ensure that the door is closed in place to prevent safety hazards such as excessive door gaps.
Energy saving: Dynamically adjust the power output according to the actual operation of the door machine. When the door is stationary, reduce the standby power of the motor; during the operation of the door, the electric energy will be reasonably distributed according to the required speed and torque. Compared with the traditional door machine control method, it effectively reduces energy consumption and achieves energy saving.
Fault diagnosis and protection: It has a complete fault diagnosis function and can monitor the operating status of the door machine system in real time. When problems such as overcurrent, overvoltage, overheating, motor failure, etc. occur, it can quickly detect and trigger the protection mechanism, stop the door machine operation, and prompt the maintenance personnel to the cause of the fault through fault codes, etc., which is convenient for rapid investigation and repair, and ensures the safe and reliable operation of the elevator door.
Communication function: Some advanced elevator door machine inverters support communication with the elevator control system, and feed back the operating status and fault information of the door machine to the elevator main control system in real time, so that the elevator can be coordinated, controlled and managed as a whole, and achieve more intelligent operation. At the same time, it can also receive instructions from the main control system, such as controlling the movement of the door according to the elevator's floor stop information.
