    • ATEX certification according to ATEX Directive 2014/34/EU for Zone 1 & 2 for using robots in explosion environment

    Ensuring the safety of the operator and equipment

    • Operators and robots share an operation area as the robot does not approach the area (Safety-Limted Position) or can continues its operation at the safety speed to secure operator’s safety (Safety-Limited Speed)
    • MELFA SafePlus safety technology support Safety functions: STO (Safe Torque Off), SS1 (Safe Stop 1), SS2 (Safe Stop 2), SOS (Safe Operation Stop), SLS (Safely-Limited Speed), SLP (Safely-Limited Position)
    • Logic for each safe I/O can be edited and in combination with the position monitoring function, a safe system can be constructed without using a Safety PLC
    • Activation the safety functions via CC-Link IE TSN Safety communication function to simplify system configuration by reducing wiring for safety devices

    Intelligent tasks are simplifying setup and maintenance by MELFA Smart Plus

    • Intelligent functions are added for enhanced force sensor control to autonomous adjust the force for optimum operation pattern
    • Autonomous startup adjustment functions are included like Robot mechanism temperature compensation function, calibration assistance function, coordinated control for additional axes
    • Predictive maintenance function which early detects abnormalities in drive system components like gear, ball screw, belt, bearing, grease… before serious failure happen and predict sudden breakdowns
    • Connectivity with Mitsubishi PLCs and FA equipment enables seamless integration

    CR800 Robot Controller

    D Type Controller

    • Standalone solution
    • Various interfaces as standard, allowing customers to build a system optimized for their applications
    • Communication interfaces for Profibus, Profinet, EtherCAT, Ethernet/IP, Devicenet, CC-Link, CC-Link IE
    • Real time control of complex movements generated by external PC retrieving position commands in real time at cycle intervals
    • Up to 8 additional axes can be controlled without using an additional dedicated control device

    R Type Controller

    • Multi CPU System up to 3CPUs (Robot, PLC, Motion, Process, CNC, C)
    • Seamless integration in iQ-R platform
    • Collision avoidance in narrow workspace
    • Coordinated control between multiple robots
    • Improves its interaction with FA equipment

    RV-FR product portfolio

    RV-CR series benefits

    Maximum performance in minimum space

    • Compared to the MELFA FR series, the MELFA CR series is lighter thanks to a simplified drive system and optimized arm structure
    • RV-CR robots achieve one of the highest-inclass payload capacity of up to 12 kg and an impressive reach of up to 1,504 mm
    • The are covering a huge range of typical applications in industries, including automotive, lithium-ion battery manufacturing, machine tending, logistics and warehousing

    Optimization of workspace utilization in various production environments

    • Their slim arms and reduced overall height make them ideal for integration with automation cells and manufacturing equipment
    • Built-in signal wiring and air piping minimize the need for external cabling
    • Tolerable amount of inertia has been significantly improved by 90% compared to the MELFA RV-13FRL, allowing high-speed movement of large objects and heavy hands.
    • High operating speed of the wrist improves cycle time in loading/unloading applications that requires many wrist movements

    Reducing the total cost of ownership

    • Designed to be cost-effective options for both large corporations and smaller manufacturers
    • Designed as lighter units with a simple structure, which directly benefits maintenance and reliability by minimizing components that require regular service
    • Thanks to Mitsubishi Electric’s latest motor technology, no backup batteries are required for its internal encoders which means no material cost and labor costs are associated with periodic battery replacements

    Ensuring the safety of the operator and equipment

    • Operators and robots share an operation area as the robot does not approach the area (Safety-Limted Position) or can continues its operation at the safety speed to secure operator’s safety (Safety-Limited Speed)
    • MELFA SafePlus safety technology support Safety functions: STO (Safe Torque Off), SS1 (Safe Stop 1), SS2 (Safe Stop 2), SOS (Safe Operation Stop), SLS (Safely-Limited Speed), SLP (Safely-Limited Position)
