| Abstract: | An automatic control system for drawing machine of ultra fine wire is introduced. The revolution speed is measured by a trans ducer and the values are calculated and PI controlled by PLC. In addition, the operating frequency of the frequency converter is controlled by the PWM output function of the PLC. Thus the adjutment of the drawing speed is implemented and the desired tension is accom plished. |
