The present project is about the design and implementation of dip coating conveyor automation system for brake shoes based on Programmable Logic Controller (PLC) technology. The PLC correlates the operation parameters control required by the user and monitors the system during normal operations and under dipping condition. Tests of dip coating system is driven by three phase AC induction motor driver using Variable Frequency Drive (VFD) controller. PLC provides higher accuracy in regulation as compared to human works, PLC is proved as a versatile and wide effective tool in industrial control of electric drives. Here it is correlating hardware and software together to control parameters of DIP coating system.
