Product Overview

The Yokogawa F3NC51-0N is a high-precision Positioning Module for the FA-M3 PLC system. It is designed for single-axis motion control, generating accurate command signals for servo motors and stepper motor systems.

Unlike multi-axis positioning modules, the F3NC51-0N focuses on high-stability single-axis position loop control, making it suitable for applications requiring precision, simplicity, and reliability in motion control.

Technical Specifications

Function and Working Principle

The F3NC51-0N performs closed-loop motion control by comparing commanded position values with encoder feedback and generating precise control outputs.

Working Principle

1. PLC CPU sends position/speed commands
2. Module calculates control output using position loop algorithm
3. Analog signal (-10V to +10V) is sent to servo driver
4. Encoder feedback is continuously monitored
5. System adjusts output in real time for accuracy
