The Application of PLC & Converter in Control System Transforming of a Gantry Planer

According to the structure and control characteristics of the main transmission system of the gantry planer,the PLC and frequency conversion technology is introduced for the control system of the traditional B2016 gantry planer in this paper.Many converters are used for the main movement and feed mechanism,an energy feedback brake device is used for the braking system,and PLC is applied to control the whole process engineering and related signals.Compared with the primary control system,the capacity is reduced by 300kW,drive efficiency is doubled,the speed range is enhanced to 1:35,static voltage error is smaller than 3%.Meanwhile,driver system is simplified greatly,maintenance workload is reduced,the reliability and the economical efficiency are highly improved.
