Approach to Sustainability

FANUC operates the businesses of FA, ROBOT, and ROBOMACHINE, as well as the IoT business that improves these three businesses. Since its foundation, we have developed a tough corporate structure by focusing on these businesses, without blindly seeking to expand the scale of its business. And we aim to remain a company trusted by stakeholders by working to provide essential value to not just customers but also to society through persistent technological innovation in all of our businesses and fulfilling our social responsibility through our business activities. Demand for factory automation is expected to continue to grow. FANUC will continue to aim to achieve SDGs by creating new value and working to resolve environmental issues such as climate change and other social issues including the need to improve work environment.

Two Perspectives on Sustainability

Two Perspectives on Sustainability

FANUC's two perspectives on sustainability are “energy saving and carbon neutrality" and “SDGs.”

Energy Saving & Carbon Neutrality

We are engaged in efforts to reduce greenhouse gas emissions, reduce power consumption, and utilize green energy by switching from hydraulic to electric power.


We will contribute to achieving 8 of the 17 goals, in particular, improving the working environment, increasing productivity, reducing waste, etc.

Initiatives in FA Business

In FA business, we provide CNCs, servo motors, and servo amplifiers which are used in machinery including machine tools and industrial machinery. Our brand new CNC model, Series 500i-A, αi-D series SERVO, and αi-D series SERVO AMPLIFIER contribute to customers’ reduction of total power consumption by realizing high machining performance, precision, and reliability while saving more energy through the application of the newest technologies.

FA products

Reduction of power consumption dependent on machining

We are working to reduce power consumption of CNC systems.

  • Development of low power consumption CNC
  • Motors optimally designed to conserve energy
  • Motor loss reduction by high-speed current control
  • Amplifier loss reduction through the application of low-loss power elements (loss reduction has been achieved continuously since the past and is currently up to 35% less than in 1995)
  • Power supply regeneration returns deceleration energy to the power supply for effective use (35% reduction compared to the resistance regeneration method in our example)

Power consumption reduction dependent on processing time

  • Control technology for cycle time reduction reduces operating time of auxiliary equipment, etc.
    • Drilling and tapping processes are sped up through the optimization of machining paths
    • Cycle time reduction through speed control that optimizes cutting load
    • Handling of the latest machining tools and technologies, such as turning through a reciprocating motion
    • Improved efficiency of peripheral device operation, etc., through faster sequence control

    High speed drilling and tapping

    High speed drilling and tapping

  • Shortening cycle time by improving the motor’s accelerating performance
  • AI thermal displacement compensation using machine learning corrects thermal displacement immediately after machine power-on. Reduces warm-up time and power consumption. (In the example below, warm-up time is reduced to 1/6.)

Power consumption reduction of the entire machine

  • Displays supplied power and power recovered by power regeneration in real time on the power consumption monitor
  • Provides an energy saving level selection function that allows selection of operation settings that prioritize machining time or power consumption, enabling confirmation of power consumption and machining time. Level can be set by confirming the power consumption amount and machining time on the CNC screen
  • Visualizes operation status and power consumption through MT-LINKi and supports optimization of machine operation
  • Reduces power consumption during trial machining by utilizing machining simulation to reduce trial machining

Initiatives in ROBOT Business

  • We conduct product development that is environmentally conscious. In the development of the CRX, the weight was significantly reduced to 40 kg, compared to the 150 kg mass of the conventional 10 kg payload class machine. This has reduced power consumption to 100-300W.
    Moreover, we have developed the same payload class machine LR-10iA/10, whose weight was reduced to 46 kg and its power consumption to 140-400W.
  • CRX


  • In addition to weight reduction, we are working on various other initiatives.  
    • Reduction and visualization of power consumption through energy-saving functions
    • Optimization of power consumption via an offline simulation software ROBOGUIDE
    • Reduction of CO₂ emissions during transportation through weight reduction
    • Peak power dispersion through nighttime operation of robots
    • Contribution to an increase in the ratio of renewable energy
