Delta door operator VFD (Variable-frequency Drive) will be launched soon

As we all know, elevators are the most common transportation facilities that people come into contact with in various buildings. They are an indispensable means of transportation for high-rise buildings and play an important role in people's daily work and life. The running speed and stability of the elevator, whether the decoration of the elevator room is beautiful or not, and whether the bell when the floor arrives is pleasant, all become one of the conditions for people to evaluate the level of the building.

???The elevator door is a very important part of the elevator. Its stability, rationality and safety are the key factors to determine the grade of the elevator. We know that the traditional door operator control method is controller + VFD (Variable-frequency Drive). In order to improve the overall performance of the elevator, Delta has developed a special VFD (Variable-frequency Drive) for the door operator according to the characteristics of the elevator door—— 004M21B-D, it is a VFD (Variable-frequency Drive) with integrated controller, its appearance can save a lot of cost for users. No failure occurred in tens of thousands of reliability tests, and has been well received by users.

???This Delta door machine VFD (Variable-frequency Drive) has the following specific functions:

1. Motor parameter setting and self-learning of the motor;

2. Self-learning door width, the action is closing-opening-closing;

3. Operation command mode: ⑴ demonstration mode; ⑵ terminal mode; ⑶ panel mode;

4. The stroke of the door knife is divided by the number of pulses;

5. When opening and closing the door, it runs at different speeds (adjustable) in different areas (adjustable), with acceleration and deceleration time (adjustable), so that the system operates with a perfect posture;

6. Running status display, door width percentage and yardage can be switched and displayed;

7. Prevent cumulative errors in pulse reception;

8. Input signal: open door, close door, light curtain, reset. Output signal: open and close door in place, middle position in place, fault;

9. The detection torque of re-opening the door is adjustable, and the range is adjustable; the abnormal deceleration time is adjustable;

10. After power off, the current door panel position can be manually moved. Power on and open and close the door signal, it can be positioned accurately and run normally;

11. Fault self-recovery function;

12. Silent type (high carrier frequency).

???China began to install elevators in the early 20th century, when elevators were imported from the West. After the founding of New China, Chinese elevator industry began to work hard, and developed and produced elevators by itself. Especially since the reform and opening up, foreign elevator companies have entered China to set up foreign-funded enterprises, and Chinese elevator industry has developed rapidly. At the same time, with the rapid development of Chinese economy, people's requirements for quality of life are getting higher and higher. How to ensure and improve the stability, rationality, and safety of elevators has become a key issue in the elevator industry; moreover, with the intensification of the energy crisis, high-efficiency and energy-saving products have become a common demand in various industries. VFD (Variable-frequency Drive) can meet the above requirements, and has outstanding energy-saving advantages, so it is particularly favored.

???Delta's VFD (Variable-frequency Drive) is one of Delta's main products in the field of electromechanical automation. It has developed rapidly in recent years. It not only has a large number of products, but also has a wide range of applications. It has a huge user base in industries such as textiles, machinery, plastics, and paper. It has now developed into one of the most important manufacturers in Chinese domestic VFD (Variable-frequency Drive) market, and its products are of excellent quality and are well received by users. In order to give full play to its advantages in technology, meet the special needs of users in different industries, and further expand its target application industries, Delta has focused on the elevator industry, and according to the special requirements and characteristics of the elevator industry, carefully researched and worked hard. After numerous successful tests, this special VFD (Variable-frequency Drive) for door operators - 004M21B-D was launched. It is a special VFD (Variable-frequency Drive) product for elevator doors, which can greatly improve the use of elevators. Performance has brought good news to the elevator industry. With the spirit of continuous pioneering and courageous pursuit and strong technical strength, Delta's special VFD (Variable-frequency Drive) for door operators will definitely meet the needs of more users, improve people's quality of life, and promote the rapid development of Chinese elevator industry.
