When a plant uses several different models to cover constant torque, variable torque, pumping, or HVAC applications, logistical complexity and associated costs skyrocket.
The FRENIC-MEGA G2 directly addresses this problem: it consolidates the functionality of multiple drive families into a single intelligent solution, simplifying system design and inventory management.

Fuji Electric Corp. of America announced the launch of the new FRENIC-MEGA G2 AC drive in September 2025, a high-performance evolution of its industry-leading FRENIC series. Building on the proven reliability and power of the original FRENIC-MEGA platform, the G2 introduces expanded capabilities that set a new standard for flexibility, efficiency, and control in general-purpose variable frequency drives.
The
drive is designed to support both constant and variable torque applications, making it ideal for a wide range of industries, including industrial operations, HVAC systems, and pumping applications.

Key Technical Specifications
Power Range
The FRENIC-MEGA G2 is available from 1/2 to 1,200 HP in 230 V and 460 V models, covering everything from small auxiliary drives to medium-to-high power applications in demanding industrial environments.
Advanced Control and Algorithms
Advanced features include sensorless vector control, permanent magnet motor (PMSM) operation, customizable programmable logic in up to 260 steps, real-time clock scheduling, a fireman's override function, and an integrated Safety Torque Off (STO) function.
Sensorless vector control is particularly relevant in applications where installing an encoder on the motor is not feasible due to cost, space, or environmental constraints. Native compatibility with PMSM motors expands the application range to include high-energy-efficiency drives, in line with current IE4 and IE5 efficiency requirements.
The integrated STO function eliminates the need for external safety relays to meet safe stop requirements according to IEC 62061 and EN ISO 13849, reducing the cost and complexity of the electrical panel.

Connectivity and Industrial Protocols:
The G2 includes native support for BACnet MS/TP and Metasys N2, with optional cards for Ethernet/IP, Modbus-TCP, Profinet, Profibus-DP, and other protocols.
This combination makes it directly compatible with the most widespread building management systems (BMS)—via BACnet and Metasys N2—without the need for additional gateways, a clear operational advantage for HVAC system integrators. At the same time, the availability of modules for Profinet and Profibus-DP opens the door to industrial automation environments with Siemens PLCs or other controllers that use these networks.

User Interface:
The keyboard uses plain English text without numeric encoding, Bluetooth connectivity, and USB access from a PC, streamlining commissioning and diagnostics without the need for specific software or proprietary cables. Bluetooth parameterization allows the drive to be configured remotely from a smartphone or tablet, which is practical for installations at height or in hard-to-reach areas.

Differential Warranty
The FRENIC-MEGA G2 includes a standard 3-year warranty, extendable up to 8 years, representing one of the longest coverages on the market in its category and reducing the total cost of ownership (TCO) for the end user.

Target Sectors and Applications:
The G2's versatility positions it in three major areas:
General Industry. Constant torque for conveyor belts, screw compressors, extruders, and mixers. The 260-step programmable logic allows the drive's behavior to be adapted to complex process sequences without the need for an additional PLC.
HVAC and Building Management. Native BACnet/Metasys connectivity, combined with variable torque support for fans and centrifugal pumps, makes the G2 a natural choice for building automation projects seeking to reduce energy consumption through variable speed control.
Pumping. The ability to manage high-efficiency permanent magnet motors and the time-based scheduling function allow for optimized pumping cycles based on actual demand, with programmed starts and stops without operator intervention.

Conclusion:
The FRENIC-MEGA G2 responds to a clear trend in the industry: the convergence of control platforms to reduce operational complexity without sacrificing performance. The integration of STO, sensorless vector control, PMSM compatibility, and multi-protocol connectivity in a single device with a power range of 1/2 to 1,200 HP makes it a robust technical solution for integrators and engineering departments that need to cover a wide variety of applications with a single product reference.
