  Intelligent Solutions

The intelligence solution will allow robots to handle various variations. And it will be able to automate the difficult task.


  Improved control performance

Produced the fastest operating performance in its class using high-performance motors and unique driver control technology developed by Mitsubishi Electric.
• Enabled high torque output at high rotational speed, shortening acceleration/deceleration time.
• Shortened positioning time for improved device throughput.
• Continuous operability improved
• Improved speed for the vertical movements that are so essential to horizontal multi-joint robot operation. 2400 mm/s, [RH-6FH: Twice as fast as the conventional speed]


 Optimal acceleration/deceleration control and optimal override control

• Optimal acceleration/deceleration times and speeds set automatically based on robot operating position, posture, and load conditions.
• Load conditions are set, enabling acceleration/deceleration times and speeds to be changed automatically according to whether a workpiece is present or not.
• This enables the maximum operating speed to be produced for each task.
• Time needed to shorten cycle times reduced.

 Improved continuous operability

Overload detection levels optimized based on the ambient temperature settings for the robot (set in the parameters). This helps improve continuous operability using load levels calculated based on actual environmental conditions for the robot axes.

The encoder temperature is monitored such that the machine is shut down due to error if the temperature exceeds the tolerable limit.

  Expanded pivotal operating range

Improved flexibility for robot layout design considerations.
Enabling more effective use of access space around the entire perimeter including to the rear.
Shortened movement distances, enabling takt times to be shortened.

Expanding the J4 axis operating range enables the posture to be changed continuously during assembly and transport operations. It also eliminates the need for the robot to move in the opposite direction partway through an operation.
Use of a flap-style arm contributes to a slimming of customer equipment, enabling operations to be completed in even closer proximity to the robot.

 Improved tooling performance

  Compatibility with internal Ethernet cable tools 

Internal installation of wiring and piping for connecting to vision sensors enabled.
• Hand: 8 input points/8 output points
• Ethernet cable for the vision sensor

  Internal routing of hand wiring and wiring channels

Internal routing of cables and air hoses is enabled through the internal channels that lead up to the end of the robot arm.
Such internal routing increases the areas of the work envelope that the robot can reach without twisting and entangling cables and hoses.
This prevents interference with cables around devices and reduces the risk of wiring disconnection.


Product Lineup
  MELFA F series (Vertical Type) 

  MELFA F series (Horizontal Type)



Mitsubishi FA products (F series)

In cooperation with various FA equipment, to achieve the customer's request.


Mitsubishi Electric has established various test cells for Mitsubishi products to commercialize automated manufacturing facilities using robots and robot-based cell manufacturing.
Mitsubishi Electric will find and solve difficulties in systems and each component, and apply the techniques obtained through such processes to robots, functions, and peripheral components to offer solutions meeting market demands.


System example with Mitsubishi FA products

Cell manufacturing

The manufacturing industry needs to handle changing challenges relating to global competition, employment/procurement, and others.
Such challenges can be solved by the "robot-based cell manufacturing",which is suitable for high-mix and various-volume production having no restrictions on places, production volume, and lead time.

Function development for automation

Intelligence solutions including sensor applications and the integrated controller iQ Platform, iQ Monozukuri containing accumulated know-how as a package, and various engineering software facilitate plan, design operation, and maintenance of robot cells, reducing the total cost of ownership (TCO).

Higher basic performance

Industry-leading performance using advanced servo control techniques and compact arms and multi-function tools suitable for cell production will improve productivity. Cooperative operation with human using the latest safety solution will further improve productivity improvement and contribute to space saving.

Improved reliability

The intelligence solution will allow robots to handle various variations, leading to a stable operation. Further, collected data will be converted into digital data to visualize robot maintenance information, leading to productivity and quality improvement.


MELFA F series

Mitsubishi Electric's goal is to "reduce TCO" ranging from plan and design to operation and maintenance. 
Mitsubishi Electric will improve the robot performance and offer the "MELFA F series", which is equipped with "e-F@ctory" and solution techniques developed and tested at its own production plants.



F series wide range of variations

The Mitsubishi Electric robot product line is equipped with all of the basic performance features desired in a robot, such as being powerful, speedy, and compact.
The variations that Mitsubishi Electric is confident meet the needs of the current era and have pushed Factory 

Automation forward in a dramatic way.
