Center Opening VVVF Elevator Door Operator - Technical Details and Features

Overview

The Center Opening VVVF (Variable Voltage Variable Frequency) Door Operator is an advanced electromechanical system designed for modern elevator applications. Utilizing VVVF control technology, it ensures smooth, efficient, and quiet operation of center-opening elevator doors, enhancing passenger safety and ride comfort.

Key Features

1. High-Performance Drive System

• The VVVF controller adjusts voltage and frequency dynamically, optimizing motor performance for both opening and closing motions1.

• Supports precise speed control with output frequencies ranging from 0.45Hz to 50Hz, allowing adjustable door movement speeds for different operational phases (acceleration, deceleration)14.

2. Dual Control Modes

• Panel Control: Manual operation via onboard buttons for maintenance and diagnostics1.

• Terminal Control: Automated operation via external signals from the elevator control system, with configurable input commands (e.g., open/close, slow-close, safety sensor inputs)13.

3. Safety and Reliability

• Integrated safety signals, including door fully open/closed feedback and obstacle detection (e.g., via light curtains or safety edges)38.

• Complies with elevator safety standards, featuring fail-safe mechanisms like automatic reversal upon obstruction detection58.

4. Compact and Robust Design

• Rated for IP40 protection, suitable for installation in elevator hoistways or car tops1.

• Operates in temperatures from -10°C to +40°C and humidity up to 90% RH (non-condensing)1.

5. Easy Installation and Maintenance

• Pre-configured wiring for encoders (e.g., 100 PPR incremental encoders) and motors simplifies setup36.

• Diagnostic LEDs and 7-segment displays provide real-time status (e.g., door position, fault codes)

FAQ
1. Are the elevator wire ropes durable?
The elevator wire rope has special provisions and requirements. Configuration is not only for wire rope and rated load, but also considered the size of the traction, as a result, the tensile strength of wire rope is greater than the weight of the lift. The safety factor is equipped with more than four wire rope. So it won't break at the same time.
2. Is it dangerous for power failure suddenly during the elevator running?
If it occurs, the elevator will automatically stop due to the electrical and mechanical safety device. In case of power failure,elevator brakes will automatically taken. In addition, the power supply departments such as planned outage, prior notice are also operating.
3. Will us be hurt when it closed suddenly?
In the closing process, if people touch the hall door, the door of elevator will automatically restart without any danger. With anti clamping switch, once the gate touched, this switching action make the elevator unable to be closed and even reopened. In addition, closing force is also available here.
4. How the elevator running?
Elevators are operated with a counterweight wire rope through the (tractor) traction drive, making ups and downs on the guide rail.
5. Is the escalator installation complicated?
We believe the functions of an escalator are not necessarily proportional to the operation complexity. Therefore, escalators designed by us apply an integrated structure, so that the equipment is more precise and more efficient and allows easier and more convenient commissioning.
6. Do you have any cerifications?
Yes, we do with ISO9001 / CCC / CE Certificates for u.
