News Release
Release of High-Performance FRENIC-VG Series of Vector Control Invertors that Achieve the Industry’s Best Control Performance

February 21,2011
Fuji Electric Holdings Co., Ltd.

Fuji Electric Holdings Co., Ltd., announces today that its core operating company, Fuji Electric Systems Co., Ltd., has released the high-performance FRENIC-VG series of vector control*1 invertors that achieve the industry’s highest level of control performance.

Calls are growing for improved productivity of equipment that uses invertors, such as machinery at production plants and factories, and conveyor cranes at seaports. Accordingly, invertors that feature high performance and multi-functionality are increasingly in demand. In response, Fuji Electric Systems is releasing the FRENIC-VG series of inverters that feature a speed response of 600 hertz, six times the level of the company’s previous models. The series achieves the high precision and detailed control required by production plants and equipment to control response speed during vector control, thereby further raising production efficiency.
Fuji Electric Systems is offering a wide range of models in the high-performance FRENIC-VG series of vector control*1 invertors to contribute to improving the productivity of customers’ production facilities and equipment.

2. Applications

　The FRENIC-VG series can be used in the following applications that require high-precision and detailed control:

Various kinds of production equipment used in steel and iron processing lines, which require speed and torque to be applied safely from extremely low speeds to high speeds
Transport equipment such as large cranes and loading-and-unloading conveyor systems, which require shifting from standstill to high torque
General manufacturing equipment such as press machines and automobile testing devices, which require responsiveness at high speeds

3. Dimensions of representative models

Common three-phase 200V and 400V models
Dimensions
7.5kW
205mm wide × 300mm tall × 245mm deep
