YX3000 series overload protection circuit for frequency inverter

Specifications

YX3000 series overload protection circuit for frequency inverter 

YX3000 Series General Purpose Frequency Inverter is specially designed for variable frequency control and energy saving.

Instruction

YX3000 Series Sensor-less Vector Control Frequency Inverter is a function enhanced product with strong stability. It takes use of Fuji 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.

Specification

Technical Features

1. Two control modes: V/F control, and sensor-less vector control;
2. Starting torque: 0.4Hz-20Hz;
3. Internal brake unit has been deployed, 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. Supports starting and stopping DC brake;
8. YX3000 is Equipped with jump frequency control, which prevents mechanical resonance and makes the system more stable and reliable;
9. YX3000 has build-in PI in order to establish close-loop control system easily;
10. YX3000 is designed with the central frequency switch function, which let the end user to fix the central frequency while it is necessary;
11. YX3000 has been equipped with RS485 communication interface, which support MODBUS protocol with ASCII and RTU forms;
12. Working with water supply accessory to realize multiple-pump stable pressure water supply function.
