Description

Engineered for highly precise motion control tasks, the Mitsubishi FX2N-20GM is an advanced, standalone two-axis positioning module designed to interface seamlessly with FX2N, FX3U, FX2NC, and FX3UC PLCs. This unit delivers independent or simultaneous dual-axis control, utilizing both two-axis linear interpolation and two-axis circular interpolation to manage complex mechanical pathways. Operating with an open collector pulse output format, it reaches a maximum frequency of 200 kHz (100 kHz during interpolation sequences), making it an excellent drive interface for high-performance stepper and servo systems.

The FX2N-20GM module houses 7.8 k steps of internal RAM program memory backed by a battery system, accommodating up to 100 motion profile blocks. Standard safety and sequence functions are natively integrated, with dedicated terminals for hardware limits, manual pulsars, home position dogs, and servo status feedback. This ensures robust axes protection and real-time synchronization in heavy-duty mechanical environments.

Features

  • Independent or simultaneous two-axis positioning control with linear and circular interpolation capability.
  • High-speed pulse train output up to 200 kHz (100 kHz in interpolation mode).
  • Flexible pulse format options: Forward/Reverse pulse trains or Pulse Train plus Direction.
  • Onboard 7.8 k step RAM program memory with integrated battery backup.
  • Flexible control units including pulses, millimeters, inches, and degrees.
  • Optocoupler-isolated digital inputs for superior noise immunity and signal integrity.
  • Direct status monitoring via onboard LED indicators for inputs, outputs, and power lines.

Applications

  • Multi-axis CNC machinery and precision metalworking equipment.
  • Automated pick-and-place gantry robots and material handling lines.
  • High-speed packaging, labeling, and rotary indexing tables.
  • Precision assembly lines requiring synchronized dual-axis positioning.

    Installation Guidelines

    • Mount the module inside a clean, enclosed control panel free from conductive dust, corrosive gas, and high moisture levels.
    • Install on a standard 35mm DIN rail or secure directly to the backplate using mounting screws. Ensure 50mm of clearance around the module for natural ventilation.
    • Establish a Class D dedicated ground connection (ground resistance of 100 ohms or less) to the ground terminal. Do not share the grounding line with heavy industrial machinery.
    • Ensure all pulse and sensor wiring is executed using shielded, twisted-pair cables. Route high-speed signal cables separate from AC power lines to avoid electromagnetic interference.

    FAQ

    Which PLCs are compatible with the Mitsubishi FX2N-20GM module?

    The FX2N-20GM is compatible with the Mitsubishi FX2N, FX3U, FX2NC, and FX3UC series PLCs. Connection to FX2NC or FX3UC series requires the FX2NC-CNV-IF or FX3UC-1PS-5V interface adapters.

    What is the maximum pulse output frequency of this module?

    The maximum output frequency is 200 kHz for independent axis operation and 100 kHz during simultaneous 2-axis interpolation operations.

    Does the FX2N-20GM require an external power supply?

    Yes, it requires an external 24 VDC (+10% / -15%) power supply, and it consumes up to 10 W of power.

    What interpolation modes are supported by this positioning unit?

    The module supports both 2-axis linear interpolation and 2-axis circular interpolation operations.

    How is the positioning program stored in the unit?

    The unit features a 7.8 k step internal RAM memory backed up by an integrated battery to retain profile configurations and program data during power interruptions.
