FRENIC VG

FRENIC Converter VG

The high-performance FRENIC-VG series of vector control1 invertors achieves 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*

*invertors to contribute to improving the productivity of customers’ production facilities and equipment.

Additional components

EMC accessories

EMC compliance filter (EFL / RF): To comply with the EMC product standard EN61800-3 for speed modifiable electrical drives, EMC compliance filters are available as substructure and external devices.
AC reactors (ACRE): For reducing low frequency current harmonics. Protects input bridges with simultaneous power converter operation.
DC reactors (DCRE): For reducing low frequency current harmonics. Increases service life of DC link capacitors.
Motor reactors: To adapt long motor cables to the inverter. To reduce voltage increase speeds.
Sinus output filter (OFLE): Reduction of leak currents and electromagnetic interferences. Similar conditions as with mains operation.

Option-cards

Comprehensive options are available, particularly for the FRN-G11S series, for example motor feedback and fieldbus interfaces (for Profibus-DP, Interbus-S, CAN open, Device Net, Modbus Plus)
