Technical Features

Two control modes: V/F control, and sensor-less vector control;
Starting torque: 0.4Hz-20Hz;
Internal brake unit has been deployed, and the braking resister can be connected outside for a quick stop;
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).
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;
Supporting multi-frequency deploy methods: digital setup, PID setup, analog quantity setup, and communication setup;
Supports starting and stopping DC brake;
YX3000 is Equipped with jump frequency control, which prevents mechanical resonance and makes the system more stable and reliable;
YX3000 has build-in PI in order to establish close-loop control system easily;
YX3000 is designed with the central frequency switch function, which let the end user to fix the central frequency while it is necessary;
