Fuji Electric works closely with transit authorities and passenger railcar builders around the world to deliver products that keep you safe and comfortable on your daily commute. Our highly-reliable transit system equipment such as the passenger door operating systems, auxiliary power supplies, and propulsion systems are used for high-speed, intercity, regional, metro, and light rail trains where reliability and safety are a must.
An installation of 3 of our FRENIC-Ace inverters and an HMI with connection via MODBUS was implemented in a restaurant in Croatia to offer customers a 360º view of the city. The task was to control the motors that are simultaneously rotating the restaurant platform, avoid any failures, and analyze and collect feedback of the application.
Our inverters control 3 of their motors, offering power control, protection against failures, speed control and maintenance warnings. Meanwhile, our HMI gives access to analytic data like current, temperature, and more at any moment.
Cleaning machines for kitchens, heaters, and air conditioners have an electric brushing solution which enters deep into ventilation ducts. Their rotating, flexible shafts must adapt perfectly to their environment without causing any damage. Fuji Electric installed our FRENIC-Mini C2 inverters into those cleaning machines, as well as our Monitouch Technoshot HMI screens.
The HMI replaced all manual keypads and push buttons and therefore modernized the machines significantly. With the FRENIC-Mini C2 and its quick response torque limitation, the cable inside the hose as well as the duct is well protected. In addition, the StopGo system stops the motor way before any breakdown can occur!
We installed our FRENIC-MEGA inverters in a garbage recycling shredder that has 2 motors of 132 kW, mechanically coupled in the same axis. The main requirements in this application were a high starting torque (overload up to 200%), a control in the load imbalance and the maintenance of speed during the process.
With our FRENIC-MEGA and its “droop-control” function, we can keep the load unbalance to a minimum. This represents a machine process control without stops, thus prolonging its maintenance!
We installed our FRENIC-Ace, 3-phase 400 V, 1.5 to 2.2 kW into a textile machine in Italy. The challenge was to control a permanent magnetic synchronous motor (PMSM) in open loop and to find a function to stop the machine with PID function in case of input phase loss.
Our solution provides a low voltage ride-through function, a best PMSM control with static pole-tuning at starting, and which has CANopen built-in.
For this installation, Fuji Electric developed a complete cabinet with EPLAN schematics. 2 FRENIC-Ace inverters with our special software for solar pumping (CLI-SOL) were installed: 1 inverter of 7.5 kW for submersible pumps (irrigation pump) and 1 inverter of 2.2 kW for water rotation pump of the lake.
A third standard FRENIC-Ace inverter was also installed for synthetic main supply, which allows the connection of any other external 230/400V AC load.
Our HMI Monitouch Technoshot allow a remote connection through VNC, so you can watch, read and save the information of the inverter and PLC of your installation or machine. This is an installation of diamond wire saw machine for cutting and processing natural stone in quarries, such as granite, marble, slate, onyx, etc.
As well as for industrial materials such as metals, composites, glass, PVC. Now our customer could upgrade and go from a totally manual process (with buttons) to a more automated and visual process!
When doing maintenance on an Uninterruptible Power Supply and its auxiliary equipment, keeping it clean is one of the main objectives. Dirt, dust, sawdust, and metal filings are just some of the pollutants that technicians see in UPSs, even when installed in seemingly clean environments. These substances can cause failures when they contaminate the contacts of relays and contactors, and conductive material can cause short circuits and malfunctions on printed circuit boards (PCBs).
At least once a year, make sure your UPS gets cleaned including a good vacuuming with a non-conductive hose and attachments. Never use a blower or compressed air! These methods can blow contaminants deeper into the unit, causing real troubleshooting headaches if and when they finally do cause issues. Use lint-free rags lightly damp with a nonflammable and fast-drying solvent for heavy deposits, and soft brushes around delicate components and connectors. Always perform cleaning work on equipment that is offline, and de-energized and with the proper personal protective equipment (PPE) such as goggles, gloves, aprons, and respirators as necessary.
Know Your Pipe and Don't Guess
Know your pipe and don't guess! This includes the customer knowing their liner and its thickness. Many customers don't know their pipe's exact specifications, but by measuring circumference and looking for a schedule embossment on a fitting, as well as referencing a pipe resource is usually a good solution.
It is also something they can research with a system engineer ahead of a flow survey or fixed installation. To that point, they could even program the measurement point(s) on the bench in air conditioning before going in the field.
Optimize Your Inverters
Get Your Installation Right
Surveying the intended installation location for straight run, and selecting a valid installation point is one of the most important tips we could offer. That is after vetting Transit Time Ultrasonic technology for the macroscopic application. This is by far the biggest battle we have in the field, even when we try to get this information upfront in our application work.
It seems that people use the basic rule of 10D up/5D down and apply it to all situations, or make no straight run considerations at all. I would highlight the need for additional straight runs for the plumbing situations that poses the biggest obstacles for us. The biggest being pumps, two elbows out of plane, valves, and T fittings. The trick is to portray this without evoking fear, just to bring them to conscious thought.

Fuji Electric VFDs are designed to handle harsh outdoor conditions needed for Agriculture Irrigation control. For this case, the ECO-DY model achieves the control by switching between two PID loops. Throughout this process, the first loop, PID1, will control the output pipe pressure. The second loop, PID2, controls the water table level. There is a sensor threshold and time that controls the switching between PID1 or PID2. One of the PID sensors will need to be a 0-10v signal and the second will need to be a 4-20ma input.
Our products are designed to operate in 50 deg C ambient under full load conditions with no derating factor. The VFDs also maintains a UL rating under single phase power input. Fuji Electric’s ECO-DY model has a standard feature of a simultaneous control of Pump pressure and water table level control. This feature will control a pump’s output pressure and automatically switch to water table level control when the level sensor goes below an adjustable threshold. This prevents costly dry run damage to the submersible pump.
Fuji Electric VFDs are a tough, rugged and designed to operate in the harsh conditions of the oil field. Our VFDs are used in thousands of Oil field pump jack applications. For this Oil Field application, they run in 50 deg C ambient at full power without derating.
In this application, our VFDs provided the standard capability to overcome the regeneration portion of the pump jack cycle without needing braking resistors. Our VFD accurately senses the regenerative energy created by the beam pump and precisely increases the speed to eliminate the need for a braking resistor.
