Mitsubishi Electric FX5-20PG-P MELSEC iQ-F Series 2-Axis Pulse Train Positioning Module

Description

Designed for high-speed, high-precision motion control, the FX5-20PG-P functions as an intelligent multi-axis control module within the Mitsubishi Electric MELSEC iQ-F Series. This 2-axis pulse train positioning module provides transistor-output pulse control to drive stepper or servo drives, delivering precise point-to-point (PTP) positioning and complex interpolation capabilities directly from the PLC backplane. It serves as an optimal solution for applications demanding multi-axis coordination and rapid path control without overloading the main CPU.

The module supports multiple control methodologies including path control, speed-position switching, and position-speed switching, offering exceptional flexibility in machine control system design. With integrated flash ROM backup, the module secures all critical positioning parameters and block start configurations without requiring an external battery, decreasing maintenance overhead and raising system reliability in demanding industrial environments.

Features

• Independent or simultaneous 2-axis control using transistor pulse outputs.
• Supports advanced path profiling including 2-axis linear interpolation and 2-axis circular interpolation.
• Multi-mode control system support: PTP control, speed control, speed-position switching, and position-speed switching.
• Highly configurable control units including millimeters (mm), inches, degrees, and pulse counts.
• Non-volatile flash ROM module data backup prevents data loss without battery requirements.
• Generous data capacity storing up to 600 positioning data blocks per axis.

Applications

• Packaging machinery (indexing conveyors, cut-to-length systems, and cartoning).
• Material handling systems, including XY gantry systems and automated sorting grids.
• Automated assembly systems requiring multi-axis pick-and-place capabilities.
• Labeling and winding systems requiring high-speed synchronization and registration.

Installation Guidelines

For reliable and safe operation, the following mounting and wiring guidelines must be observed:

• Mounting: Mount the module securely onto a standard DIN rail or directly to the panel board inside a protective control cabinet to minimize vibration.
• Wiring Shielding: To prevent signal degradation and electromagnetic interference (EMI), always use shielded twisted-pair cables for pulse train output lines and high-speed I/O.
• Grounding: Connect the grounding terminal directly to a dedicated class D ground (grounding resistance of 100 ohms or less) using the shortest path possible. Do not share the grounding wire with high-power equipment.
• Power Supply Routing: Route the 24 V DC external power supply cables separately from high-voltage AC power lines to avoid induced electrical noise.
