The elevator door is a very important part of the elevator. Its stability, rationality and safety are the key factors determining the elevator class. We know that the traditional door control method is controller + frequency converter. In order to improve the overall performance of the elevator, Delta developed a special inverter for door machine - 004M21B-D for the characteristics of the elevator door, which is an integrated control. The frequency converter of the device can save a lot of cost for the user. In the tens of thousands of reliability tests, no faults occurred, which was highly praised by users.
This Delta door drive has the following specific functions:
1. Motor parameter setting and self-learning of the motor;
2. Self-learning door width, the action is to close the door - open the door - close the door;
3. Running command mode: (1) demo mode; (2) terminal mode; (3) panel mode;
4. The stroke of the door knife is divided by the number of pulses;
5. When the door is opened and closed, it can be operated at different speeds (adjustable) in different areas (adjustable), and there is acceleration/deceleration time (adjustable) to make the system run in perfect posture;
6. The running status shows that the door width percentage and the number of codes can be switched and displayed;
7. Prevent pulse acceptance from accumulating errors;
8. Input signal: open the door, close the door, light curtain, reset. Output signal: switch door in place, intermediate position in place, fault;
9. The detection torque of the reopening door is adjustable, the range is adjustable; the abnormal deceleration time is adjustable;
10. After the power is cut off, the current door position can be manually moved. Power on to the switch door signal, can be accurately positioned, normal operation;
11. Fault self-recovery function;
12. Silent type (high carrier frequency).
In China, elevators were installed from the beginning of the 20th century. At that time, the elevators were imported from the West. After the founding of New China, China's elevator industry began to work hard and independently develop and produce elevators. Especially since the reform and opening up, foreign elevator companies have entered China to set up three-funded enterprises, and China's elevator industry has developed rapidly. At the same time, with the rapid development of China's 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, efficient and energy-saving products have become a common demand in various industries. The frequency converter can meet the above various requirements, and the energy saving advantage is outstanding, so it is particularly favored.
Delta inverter is one of the main products in Delta's electromechanical automation field. It has developed rapidly in recent years. It not only has many products, but also has a wide range of applications. It has a large user base in the textile, machinery, plastics, paper and other industries, and has now developed into a domestic One of the most important manufacturers in the inverter market, the product quality is excellent, and is highly praised by users. In order to give full play to its technological advantages, meet the special needs of users in different industries, and further expand its target application industry, Delta looks at the elevator industry and carefully develops and strives to develop and adapt to the special requirements and characteristics of the elevator industry. After numerous successful trials, this special inverter for door machine - 004M21B-D was introduced. It is a special inverter product for elevator doors, which can greatly improve the performance of elevators and bring good news to the elevator industry. With the spirit of continuous development and the pursuit of strong technical strength, Delta's special inverters will meet the needs of more users, improve people's quality of life, and promote the rapid development of China's elevator industry.
Leading the new technology of elevator door control - Delta door machine inverter will be available soon
As we all know, elevators are the most frequently used transportation facilities in various buildings. They are an indispensable transportation tool for high-rise buildings and play an important role in people's daily work and life. The running speed and stability of the elevator, the aesthetics of the elevator room and the sound of the bells arriving at the floor have become one of the conditions for people to evaluate the building level.
