【Abstract】 The control principle of high frequency vibrator was analyzed in this paper. In order to reduce the cost of the equipment in paper manufacturing industry and replace the servo motor to control the position of the vibrator amplitude,adopting S7-1200 PLC as the core controller to control the frequency converter and the asynchronous motor in order to realize accuracy control. A working system of vibrator based on asynchronous motor controlled by the frequency converter was designed,which included the hardware and software design,meanwhile adding touch panel contributed to the convenient control. The experiment results showed that this system could quickly and reliably achieve the requirements of the control and saved about 15% cost of the electrical equipment.更多还原
