Hello everyone! My name is Vidy, and I'm excited to share that I'm diving into the world of PLCs and PLC programming. As part of my final year project, I’ve been given the challenge of programming a PID controller using Mitsubishi GX Developer to work with a stepper motor and an incremental encoder. The goal of my project is to enhance the movement and speed of an Automated Guided Vehicle (AGV). As I'm just getting started with ladder programming, I could really use your guidance and expertise. I'm currently working with a Mitsubishi FX3U PLC and need to connect it to a hybrid stepper motor and an encoder. If anyone has tips, resources, or solutions to share, I would greatly appreciate it! Thank you for your support!
Welcome! You can download the Mitsubishi JY997D16701 manual, which serves as the comprehensive guide for analogue control in the FX series of PLCs. This manual is essential for understanding analogue control techniques and features numerous programming examples to enhance your learning experience. Happy learning! - Steve
I have reviewed the manual, but many concepts remain unclear since this is my first experience working with a Programmable Logic Controller (PLC). I'm looking for a comprehensive guide or tutorial on using ladder logic for programming the PID controller specifically for Automated Guided Vehicles (AGVs). Any resources or step-by-step instructions would be incredibly helpful!
It seems you may be venturing into territory that is beyond your current level of expertise. This particular project is quite challenging and may be too complex for someone just starting out.
Stepper motors operate without the need for a PID (Proportional-Integral-Derivative) controller.
If you're embarking on your first PLC programming journey, it’s important to avoid "starting from the roof." Instead, begin with the basics, such as understanding contacts and coils. Once you grasp these foundational elements, gradually progress to more complex concepts like mathematical operations and bit manipulation. This step-by-step approach will enhance your understanding of the manuals and improve your programming skills effectively.
