AVF80 Series Sensor-less Vector Control Frequency Inverter ( also termed frequency converter ,frequency inverter, adjustable-frequency drive, variable speed drive, AC drive, micro vfd or vfd inverter ) is a function enhanced product with strong stability.
It takes use of Infineon IGBT and the TI DSP chip set, completely optimizes vector control and V/F control. It has been widely deployed in various industrial environment, and special in situations requiring speed control precision pump torque response speed and low-frequency output.
Technical Features
1. Two control modes: V/F control, and sensor-less vector control;
2. Starting torque: 0.4Hz-20Hz;
3. Support brake units, and the braking resister can be connected outside for a quick stop;
4. Five kinds of V/F control, which are constant torque V/F curve, One kind of customer defined V/F curve, 3 kinds of down torque curve (2.0/1.7/1.2 times the power).
5. Through PLC or internal control terminal, multi-speed control and PID control could be realized. And users could combine a variety of operating modes while it’s necessary;
6. Supporting multi-frequency deploy methods: digital setup, PID setup, analog quantity setup, and communication setup;
7. AVF508 is Equipped with jump frequency control, which prevents mechanical resonance and makes the system more stable and reliable;
8. AVF508 has build-in PI in order to establish close-loop control system easily;
9. AVF508 is designed with the central frequency switch function, which let the end user to fix the central frequency while it is necessary;
10. AVF508 has been equipped with RS485 communication interface, which support MODBUS protocol with ASCII and RTU forms;
11. Working with water supply accessory to realize multiple-pump stable pressure water supply function.
