III. Automation, HMI & Power Control Business (Core Business)
While brands like Weintek or Allen-Bradley focus heavily on software ecosystems, Fuji Electric’s core automation business is defined by the perfect synergy between heavy power control (FRENIC) and visual interface (MONITOUCH). Fuji provides the critical hardware that allows operators to safely command massive electrical loads while visualizing real-time energy data and machine diagnostics.

1. Core Control and Visualization Products
MONITOUCH HMI Series (V9 / HG / UG Series)
The MONITOUCH is Fuji’s flagship visual interface. Ranging from compact 3.5-inch operator panels to expansive 15-inch wide-screen touch monitors, these HMIs are famous for their brilliant, high-contrast LCD screens that remain readable under harsh factory lighting. They serve as the central nervous system for packaging machines, CNC equipment, and water treatment plants, offering advanced data logging, recipe management, and multi-language support.
FRENIC Variable Frequency Drives (VFDs)
The FRENIC series (including the FRENIC-Mega, Eco, and Aqua lines) represents the "muscle" of Fuji’s automation business. These drives control the speed and torque of industrial motors. Crucially, they feature advanced, detachable LCD keypads that act as localized visual displays. These keypads allow maintenance technicians to view real-time oscilloscope-like waveforms, monitor energy savings, and troubleshoot fault codes directly at the drive without needing a laptop.
Tellus HMI Configuration Software
Tellus is Fuji’s powerful, highly intuitive programming environment for the MONITOUCH series. It allows engineers to drag and drop complex industrial vector graphics, write C-style macro scripts for edge computing, and set up extensive alarm histories. Tellus is widely praised for its massive, built-in library of communication protocols, allowing Fuji HMIs to talk to almost any PLC brand on the market natively.
MICREX PLCs and Edge Controllers
Fuji’s programmable logic controllers provide the high-speed logic execution required for discrete manufacturing. Modern iterations of these controllers are integrated with edge-computing capabilities, allowing them to preprocess machine data and push it directly to the MONITOUCH HMI or up to cloud-based SCADA systems via MQTT and OPC UA.

2. Technical Highlights of the Automation Business
Built-in Oscilloscope and Trending: Both the MONITOUCH HMI and the FRENIC VFD keypads feature built-in trending and oscilloscope functions. Operators can visually graph motor torque, speed deviations, or temperature spikes over time directly on the screen, making mechanical troubleshooting incredibly fast.
Energy Visualization and Eco-Mode: Because Fuji specializes in power electronics, their HMIs and drives feature native "Eco" modes and energy-monitoring macros. The displays can visually calculate and show the exact amount of kWh saved and CO2 emissions reduced by utilizing the FRENIC drive, providing instant visual ROI for plant managers.
Extreme Environmental Ruggedness: Fuji offers specialized MONITOUCH HMIs with IP67/IP69K front-panel protection, capable of surviving high-pressure caustic washdowns in food processing. Their VFDs feature conformal-coated PCBs to resist corrosive gases and conductive dust.
Seamless IIoT Routing: Modern MONITOUCH HMIs act as protocol converters and IIoT gateways. They can read proprietary data from a legacy serial PLC, convert it to Ethernet/IP or MQTT, and visually display it locally while simultaneously routing the data to an enterprise SQL database.

3. Industry Application Solutions
Water and Wastewater Treatment: Fuji’s FRENIC-Aqua drives are specifically engineered for pumps and blowers. Paired with rugged MONITOUCH HMIs installed in outdoor, high-humidity control cabinets, they provide operators with visual PID loop tuning, pipe pressure trends, and pump-alternation logic.
HVAC and Building Automation: In commercial skyscrapers and data centers, Fuji VFDs manage massive chillers and Air Handling Units (AHUs). The HMIs serve as local BMS (Building Management System) dashboards, visually optimizing airflow and minimizing the building's carbon footprint.
Material Handling and Cranes: Fuji’s FRENIC-Mega drives feature specialized hoist and crane logic, managing mechanical brakes and high starting torques. The operator cabin HMIs visually display load weights, wind speeds, and anti-sway parameters to ensure safe lifting operations.
