FRENIC-Ace (E3)
Fuji Electric FRENIC-Ace (E3) Variable Frequency Drives
The FRENIC-Ace (E3) is the next-generation evolution of the widely installed FRENIC-Ace E2 platform, covering 1/8 HP to 30 HP on 230 VAC and 460 VAC three-phase supplies. It keeps the E2's application focus — HVAC, pumps, fans and general industrial machinery — while improving motor control performance, efficiency and network connectivity in a compact footprint.
What the E3 generation adds
- Improved harmonic mitigation, easing compliance where supply distortion limits are tight
- Higher ambient temperature operation for warm plant rooms and tightly packed enclosures
- Expanded fieldbus options, including EtherNet/IP and PROFINET via optional communication cards
- Enhanced energy efficiency across the load curve
Carried over from the E2
Built-in PID control for closed-loop pressure and flow regulation, auto-tuning, V/f and sensorless vector control modes, and RS-485 Modbus RTU as standard. Protection covers overcurrent, overvoltage, undervoltage, motor overload, short circuit and ground fault. The E3 remains compatible with the established FRENIC accessory ecosystem — AC line reactors, dV/dT output filters and remote keypads all carry over.
Typical applications
Building HVAC fans and pumps, process circulation pumps, conveyors, mixers, and OEM machinery where a compact general-purpose drive with modern Ethernet connectivity is required. UL/cUL listed and CE marked. If you are standardizing a panel design on the E2 and evaluating the migration, our application team can confirm parameter and footprint differences before you commit.
