A converting circuit was proposed based on frequency-multiplier circuit for linear servo motor and PLC interface. This paper introduced the control modes of linear servo motor, and then emphasized the components of the circuit system,included hypo-circuits＇ hardware design such as level converting circuit, frequency-multiplier circuit and differential signal circuit. This converting circuit can not only solve the variance problem between the output voltage of PLC and control signal voltage of linear servo motor; but also ensure linear servo motor operate smoothly with frequency- multiplier circuit. The anti-jamming capability of the system was improved with the differential circuit. As a result, this converting circuit is recognized widely in practical application
