CONTROL AND MONITORING OF A TWO-AXIS AC-SERVO POSITIONING SYSTEM FOR DISPENSING APPLICATIONS USING PLC S7-1200

Abstract

The high-speed pulse train output (PTO) function is focused on in this paper, aiming to accurately control the speed and position of two-axis AC-Servo motors for precise dispensing applications. Additionally, attention is directed towards the design of the control interface and system monitoring using WinCC software. The control device used in this project is the PLC S7-1200. The main objective of this study is to develop a logic program that allows for the precise control of the position of the Servo motors and provides a control interface and monitoring system for assessing the system's operation and performance. The project encompasses the construction of the practical system, the programming of the PLC control device through TIA Portal software, the implementation of position control algorithms, the design of the control interface, the monitoring of actual positions, and the ensuring of safety measures. From the defined objectives and the completion of the hardware construction, software programming, and SCADA interface design, the following results have been obtained: optimized hardware design and construction, proper electrical panel wiring, accurate control of the position of the two-axis AC Servo, precise dispensing of the liquid solution, and an intuitive control and monitoring interface. Compared to previous studies, the novelty of our research lies in the ability to accurately control multiple axes with high-speed capability, accurately quantify the dispensed liquid through quantitative experimental results, and design a visually appealing and user-friendly control and monitoring interface.
