Energy-efficient Products/Waste Reduction
Energy-efficient Products
FANUC will continue to make energy-efficient products, which will contribute to conserve energy in our customers' factories.
| Development of large-capacity servo motors | We have developed a high-precision, high-efficiency, large-capacity servo motor fully utilizing our advanced digital control system. In the field of industrial machines, including electric injection molding machines, which require tremendous power, we have realized energy saving by introducing this large-capacity servo motor in place of hydraulic pressure. |
|---|---|
| Adoption of power supply regeneration system | In the servo amplifier, we use a power supply regeneration system that returns energy to the power supply when the motor decelerates. This effective use of the power supply leads to energy savings. When mounted on a ROBODRILL, it achieves a reduction in energy consumption by approximately 35% compared with the resistance-regeneration method. Furthermore, the adoption of new power devices has continuously reduced energy loss of the servo amplifier. It is reduced by maximum 35% compared to that in 1995. |
| Provision of the latest servo system | The newly developed αi-D series SERVO system has reduced loss of the entire servo system by 10% compared to the conventional products by reducing copper loss and iron loss of motors and AC reactors by adopting the above amplifier. |
| Power consumption monitoring function | Through the power-consumption-monitoring function, we have made it possible to monitor the amount of power consumed by our CNC systems, enabling the efficient adjustment of the cycle time. In addition, CO2 emissions can also be displayed. By using the energy-saving level-selection function, we have made it possible to choose the type of operation: one that prioritizes cycle time and one that prioritizes power consumption. When there are differences in cycle times in the production line, in case fast processing is not necessary, choosing the power consumption priority operation contributes to energy savings for the entire factory. In addition, robots can also display power consumption in real time on the teaching operation panel using a power consumption monitor. |
| Fast Cycle-time Technology | This series of functions reduces cycle time. Reducing operating time contributes to reductions of energy consumption by peripheral equipment, such as a coolant pump. |
| Averaging the load of power demand | Night operation using robots disperses peak power and curbs power consumption. |
| Reducing CO2 emissions by reducing weight | The design of the robot mechanical arms with lighter weight also reduces power consumption. For the robots with a payload of 165 kg, the Robot S-430iW in 1997 weighed 1,300 kg while the Robot R-2000iC/165F in 2013 is lighter with weight of 1,190 kg. In addition, the collaborative robot CRX has a robot mass of 40 kg with a payload of 10 kg, which is considerably lighter than the robot mass of 150 kg common to robots in the same class thus far, and reduces power consumption. Even the LR-10iA/10 fully enclosed handling robots are more than 1/3 lighter than conventional robots with the same 10 kg payload, and consume 30% to 40% less power. |
| Optimal operating program | By optimizing the operating program with ROBOGUIDE, power consumption is reduced and the lifetime of the reducer is extended to reduce running costs. |
| Efficient robot utilization | Use of an autonomously moving, Automatic Guided Vehicle (AGV) with collaborative robots allows a single robot to work in multiple locations, improving the efficiency of robots. This reduces standby power, compared with installing multiple robots. In addition, the latest model of the collaborative robot CRX has a very light robot mass of 40 kg, and the AGV can also be made compact. Furthermore, the CRX can be moved on a handcart instead of on an AGV, making it possible to move the robot to the place where and when it is needed. |
| Instruction operation panel backlight automatically turns off | Reduces power consumption by automatically turning off the backlight of the LCD screen on the robot's teaching operation panel when no operation is performed for a certain period of time. |
| Energy-saving design | We have developed a new type of heavy payload robot, M-1000iA, with a serial link mechanism that is compact and has a wide motion range. Using the latest structural analysis, the M-1000iA has the necessary strength and rigidity while making extensive use of curved surfaces, at the same time, saving energy through the use of arms designed to be lightweight and power regeneration that reuses the robot's deceleration energy. In addition, we have developed the R-50iA, a new robot controller with an eco-friendly, energy-saving design, which reduces power consumption through the use of low-power fans, amplifiers with low-loss power elements, and highly efficient brake control. |
| Highly reliable automatic wire feeding system (AWF3) | ROBOCUT is capable of unmanned operation for long periods, thanks to the highly reliable automatic wire feeding system AWF3, which can automatically recover feeding even when a wire is accidentally cut and disconnected. Stable night-time machine operation disperses peak power usage and curbs power consumption. |
| Discharge control iPulse3 | With ROBOCUTs, our newly developed discharge control iPulse3 has reduced the processing time and achieved a reduction in power consumption. In addition, power consumption is reduced by inverter control of the pump and cooler, power regeneration of the discharge circuit, and reduction of standby power for various devices. |
| Electrification of peripheral equipment | With the additional axis option for ROBOSHOT, peripheral equipment that was previously driven by hydraulic equipment can be electrified, saving energy. |
| Heat insulation cover | Covering heaters of injection cylinders of ROBOSHOTs with heat insulation cover increases heat insulation effect and reduces power consumption. |
| Plasticization energy monitor | By visualizing the breakdown of the energy consumed in the plasticization process (melting of the resin) and the energy loss due to heat dissipation, it supports the adjustment of optimal molding conditions that reduce energy consumption. |
| Energy-saving functions | The ROBODRILL's sleep function reduces power consumption by turning off the servo motor, stopping the coolant and lubrication pumps while the machine is idle. Furthermore, the peripheral device and mist collector control functions make it easy to extend the same control to other devices, saving energy for the entire system. |
