Application of PLC Frequency Conversion in Bridge Crane

Jun‐Wei Wang

Abstract

This paper applied programmable logic controller(PLC) to the frequency control and speed regulation of a bridge crane,and programmed the software to achieve PLC communication and PID control.This system could realize the real-time monitoring of on-site operation condition and query performance data.We could start and stop the motor,set the operating frequency through interactive interface.The speed regulation system of traditional bridge crane was improved,and the reliability and operability were improved too.
