Fuji Electric released high-performance FRENIC-VG series of vector control invertors that achieve the industry’s best control performance

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.


1. Features of the series
FRENIC-VG
(1) Enhanced control performance
  • Improved speed response of 600Hz
  • Improved torque control accuracy of ±3%
  • Speed control accuracy of ±0.005% (when using a dedicated PG induction motor)
(2) Numerous optional cards available
  • A lineup of optional cards for various interfaces including the E-SX high-speed synchronized communications card, PG interface card, and safety card※2
(3) Conformity with safety standards
  • Conforms with ISO 13849-1 safety standards for EN terminals of inverters
  • Conforms with IEC 61508 SIL2 safety standards for optional cards
(4) Equipped with servo functions※2 including controls and pulse-line orientation※3 for internal APC
(5) A total of 40 models are available for a wide variety of applications
  • 16 three-phase 200V models ranging from 0.75kW to 90kW
  • 24 three-phase 400V models ranging from 3.7kW to 630kW
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
30kW
326.2mm wide × 550mm tall × 261.3mm deep
Notes:
  1. Vector control is a method for controlling the instantaneous torque of induction motors by controlling an inverter’s output frequency and output voltage.
  2. These functions will be available in the near future.
  3. This function is optional.
