我在五福彩票平台输了很多钱AS320 elevator inverter is a kind of newly developed frequency inverter especially for elevators. It is designed with 32-bit MPU for motor driving, high performance complex programmable logic device (CPLD), and advanced power module. Meanwhile, the elevator inverter is designed based on international advanced closed loop vector control technology and supports various control modes including V/F control, sensorless vector control, and torque control modes. Integrating the characteristics of potential energy load, the elevator inverter allows elevators to operate efficiently, smoothly and steadily, and offers passengers a comfortable feeling.
我在五福彩票平台输了很多钱While designing the AS380 elevator integrated drive and controller, a variety of factors, including elevators' safety and reliability, inherent characteristics of elevator operation, and potential energy load characteristic of elevators, are taken into consideration. Designed based on variable frequency speed regulation technology and elevator control technology, the elevator integrated drive and controller is an ideal combination of an elevator drive and an elevator controller. Its dual 32-bit embedded microprocessor unit allows it to complete both elevator operation and motor drive functions. The multiple elevator operation functions can satisfy customers' different application requirements.
AS500 general vector inverter is a newly developed frequency inverter designed to satisfy market demands. It is designed based on international advanced speed sensorless vector control technology, closed loop vector control and torque control technology. The vector inverter offers not only superior control performance as high end frequency inverters, but also improved reliability and environmental adaptability, as it is designed and manufactured to satisfy customers' varied application requirements and various industrial demands.
我在五福彩票平台输了很多钱The electric drive uses a MENTOR II DCVV speed regulator produced by British CT, and there is no need for electric generator set. By changing the voltage on the brush of the motor, the motor speed can be modulated. Hence, an elevator controlled by the DCVV control cabinet offers a comfortable feeling, improved operation efficiency and reduced energy consumption. The full serial DCVV control cabinet uses an absorption circuit and a DC reactor to greatly reduce the operation noise. Our control cabinet is suitable for different kinds of DC elevators.
1. Assembled with a full serial control system, our VVVF control cabinet is able to fulfill multiple humanized functions such as duplex control, group control, remote monitoring, emergency rescue, etc. 2. The excellent VVVF drive system assembled in our full serial VVVF operating box ensures higher stability of the elevator and offers a better elevator travelling experience to passengers. 3. CAN bus serial communication method greatly reduces the quantity of cable cores and saves the cost spent on wiring.
