FRENIC-MEGA (G2) — general-purpose frequency converter 0.4–710 kW, 200/400 V
Country: Japan · Model: FRENIC-MEGA (G2)
The general-purpose frequency converter FRENIC-MEGA (G2) controls low voltage motors from 0.4 to 630 kW, and in some versions up to 710 kW, in three-phase 200 and 400 V networks. It is used on pumps, fans, HVAC and water supply systems, conveyors, cranes and process machinery.

Description
Starting torque is at least 200 % for models up to 22 kW and at least 180 % from 30 kW, so a machine starts under load without oversizing the drive. The unit controls induction motors and permanent magnet synchronous motors, with sensorless vector control or with a speed sensor. Compared with the previous generation, the control range is wider and control quality is improved. The Customization Logic function holds many more program steps, it is written through a PC loader, and on simple installations a separate controller is often unnecessary. Network interfaces and standardised safety functions simplify integration into a process control system, and data under the Ecodesign Directive is published. For setup from a phone there is the FRENIC Mobile Loader app.
How to choose
The frame size is chosen by motor current and load type. A pump or fan is fine in normal duty HND, while cranes, conveyors and machines with a heavy start need HHD, which at 400 V runs from 75 to 630 kW. Versions are basic, with a built-in EMC filter, with a zero-phase reactor or with a DC reactor. For rolling mills and lines with a common DC bus, FRENIC4400 inverters of 690–2100 kVA per unit or FRENIC4000 up to 300 kVA are more appropriate.

FAQ
Does the FRENIC-MEGA (G2) work with permanent magnet synchronous motors?
Yes, they are supported as standard, along with induction motors. A speed sensor is fitted when accuracy at low speed is needed, otherwise sensorless vector control is enough.
Is the FRENIC-MEGA (G2) available in 230 and 460 V versions?
Yes, in North America the series is offered for motors from 1/2 to 1200 hp at 230 and 460 V.
How to get EN 61800-3 category C2 compliance for the FRENIC-MEGA (G2)?
For converters up to 22 kW the manufacturer supplies an external EMC filter, with which the drive complies with category C2.
Can a separate PLC be avoided with the FRENIC-MEGA (G2)?
On simple machines yes, since Customization Logic runs user logic right in the converter. Network interfaces provide the link to the upper level.
