is a high-performance 2.2 kW to 3.7 kW (3 to 5 HP) variable frequency drive from the FRENIC-Ace (E2) series. Unlike the basic Micro or Mini series, the "Ace" line features a multi-rating system that allows the drive's output to be adjusted based on the specific load type (e.g., fans vs. heavy machinery).

Primary Control Functions
Built-in PLC Logic (Customizable): This is the Ace's standout feature. It has a built-in logic controller (up to 200 steps). You can program it to handle timers, counters, and digital I/O to manage machine sequences without an external PLC [1, 2].
Triple/Quadruple Ratings: A single drive can be "tuned" to different motor sizes based on your load:
Normal Duty (ND): Best for fans/pumps, allowing a larger 3.7kW (5 HP) motor at 6.9A.
High Heavy Duty (HHD): Best for mixers/crushers, providing 200% overload protection for a 2.2kW (3 HP) motor [3, 4].
Safe Torque Off (STO): A built-in hardware safety feature (SIL3/PLe) that ensures the motor cannot generate torque during an emergency stop, eliminating the need for bulky external safety contactors [2, 5].
Operational Capabilities
Universal Motor Control: It can run standard Induction Motors as well as high-efficiency Permanent Magnet (PM) Synchronous Motors, which are the standard for modern energy-saving goals [2, 4].
High-Speed Operation: Capable of outputting up to 500 Hz, which is required for high-speed spindles and specialized precision manufacturing [4].
Advanced Sensorless Vector Control: Maintains extremely stable speed and high torque even at very low speeds without needing a motor encoder [2].
Dynamic PID Control: Includes advanced PID for maintaining constant pressure or flow, featuring "anti-windup" logic to prevent system overshooting.
Safety & Maintenance
Removable Control Terminals: The entire control wiring block can be detached. If you need to replace a drive, you can just unplug the wires and plug them into the new unit without re-wiring [2].
Predictive Life Diagnostics: It monitors the "health" of its own cooling fans and internal capacitors, giving you a warning signal when they reach 90% of their life [2].
Dual RS-485 Ports: It features two communication ports as standard, allowing you to connect an HMI (Touchscreen) and a PC for programming at the same time [2].
Connectivity
Standard Modbus RTU: Built-in for networking.
Expandable: Unlike the Mini/Micro, the Ace can accept optional cards for Profibus, DeviceNet, CANopen, and CC-Link to fit into any factory network [2, 4].
