FAQ I. Why have abnormal operation in vector control 2 without encoder speed feedback? (1) Check if there exists large difference between the motor rated current and inverter rated current (2) Check if complete motor data identification has been performed (3) Check if the lines for Hall sensor is loosen or dislocated for V5−H−4T18.5G/22L and above power class II. Why have abnormal operation in vec...

I.Why occur over current trip or over load trip in vector control 2 with encoder speed feedback? Check the parameter settings: (1)Check if the motor parameters are properly set (2)Check if the encoder pulse Pd.21 is properly set (3)Check if the encoder direction parameter of Pd.22 is properly set (4)Check if the ratio between motor and encoder Pd.24 is properly set Check the hardware connection (1...

The ac drive controls the speed of the pump and fan by changing the electrical energy supplied rather than damping the air- or water flow. It is like reducing the speed of a car by pressing less on the accelerator instead of using the brake to slow down the speed. The payback time of an ac drive is typically one year or less. Other benefits of using ac drive to control the speed of fan or pump are...

Today’s VFD are available in compact form factors and can reliably operate motors of all sizes, across a span that may range from nearly 0Hz all the way up to 400Hz. This is quite a range compared to the nominal 60Hz fixed speed. Not only that, but precise speed control of 0.01Hz resolution with an accuracy of 1% of maximum output frequency is possible. Similarly, torque control can apply up to 20...
