A general design of control system in artificial grass tufting machine, realizing the safe and stable operation, is presented in this paper. Servomotors were adopted in this machine instead of stepper motors and induction motors which were usuallyused in the past. In this control system, the communicationbetween motion controller LMC20 and variablefrequency drive ATV71, OTB module, servo drives, detection module and other equipment is achieved by CANopen bus. Developedby CoDeSys, the touch screen with humanized operation interface can realize the functions of signal acquisition, working state display,control, protection, etc. The control system has been put into operation in factory.
