| Abstract: | Aiming at several mistake viewpoints in the application of the frequency converter in the high inclinationangle downward belt conveyer,this paper analyzes the operation features of the belt conveyer,mechanical characteristics of the motor and the principles of the power generation feedback of the frequency-converter,and explains the source of the mistake of the above viewpoints. In order to choose and use frequency converter reasonably,the control schemes of the high inclination-angle downward belt conveyer completing startup and power generation feedback when adopting the 2-quadrant transducer and the 4-quadrant transducer,is proposed. |
