Precise control of door operator operation: It can implement multi-segment speed control for the three-phase AC door operator motor. It can match the speed based on the encoder input signal to the door position, or switch speeds via sensor input. For example, it can rapidly accelerate during the initial opening of the elevator door and automatically decelerate when approaching full opening or closing to avoid door impact, ensuring a smooth and stable opening and closing process and improving the passenger experience. Furthermore, it can independently set the door holding frequency and torque to prevent the door from swaying unnecessarily when open.

Self-adaptation of door parameters: Equipped with a door width measurement function, after elevator installation or maintenance, without complex manual adjustments, the inverter can automatically detect and record key parameters such as the elevator door opening width. Subsequent operation will control the door operator's actions based on these parameters, ensuring that the door opens precisely to the set width each time, avoiding problems such as insufficient or excessive opening.

Establishing a system linkage and monitoring channel: Equipped with an RS485 communication interface, it can interact with the elevator main control system via a dedicated protocol. On one hand, it can receive door opening and closing commands from the main control board and execute corresponding actions; on the other hand, it can also feed back data such as the door operator's operating status, speed, and current to the main control system, facilitating settings and real-time monitoring by staff via the main control terminal. Simultaneously, its dedicated input terminals and 3-point relay outputs can also adapt to signal input and feedback from sensors, limit switches, and other accessories, ensuring smooth linkage between the door operator system and other components.

Ensuring door operator operational safety: Relying on its own circuit protection design and linkage with external accessories, it can achieve multiple safety protections. For example, when abnormalities such as door operator motor overload or circuit overvoltage are detected, it can promptly suppress voltage or current, or even stop the inverter from working, to prevent damage to the motor and inverter; when the door catches a foreign object, it quickly adjusts the torque in conjunction with sensor signals, triggering the door to open in reverse to prevent injury to passengers or damage to items.
