Specification

SEODescription

The Mitsubishi FX5-20PG-P Module is a high-performance MELSEC iQ-F Positioning Module designed for precision motion control, offering 2-axis FX5-20PG-P Pulse Output with support for differential (LINE driver) or open-collector configurations. It integrates seamlessly with FX5U/FX5UC PLCs, enabling direct connection to up to 16 expansion modules while supporting Ethernet, RS-485, and MELSEC communication protocols for synchronized control of servo drives. Operating at 24 VDC (±10%) with a temperature range of 0–55°C, this module is ideal for industrial automation applications like CNC machinery, robotics, and packaging systems. Its key advantages include high-speed pulse output (up to 4 MHz), flexible positioning modes, and simplified parameter configuration via GX Works3. However, it lacks built-in digital I/O channels, requiring additional modules for sensor integration, and may demand specialized expertise for advanced motion programming.
