The Fuji Electric FRN0029E2S-4GBX (FRENIC-Ace) is a sophisticated, "all-round" high-performance drive. While the Micro and Mini series are for simple speed control, the Ace series is designed for complex automation, offering built-in logic and safety features that can often replace external controllers.
Primary Control Functions
Built-in PLC Logic (Customizable): This is the "brain" of the Ace series. It features a built-in logic controller (up to 200 steps). You can program it to handle digital inputs/outputs, timers, and counters to manage machine sequences without an external PLC.
Triple/Quadruple Ratings: A single drive can be optimized for different motor sizes and load types:
Normal Duty (ND): Best for fans/pumps, allowing a 200 HP motor at 28.5A.
High Heavy Duty (HHD): Best for mixers/crushers, providing 200% overload protection for a 10 HP motor at 18.0A.
Safe Torque Off (STO): A built-in hardware safety feature (SIL3/PLe). It ensures the motor cannot generate torque during an emergency stop, allowing you to meet global safety standards without using bulky external safety contactors.
Operational Capabilities
Universal Motor Support: It can control standard Induction Motors as well as high-efficiency Permanent Magnet (PM) Synchronous Motors, making it a future-proof choice for energy-saving initiatives.
High-Speed & Precision: It can output up to 500 Hz, necessary for high-speed spindles. Its Sensorless Vector Control maintains extremely stable speed even if the load changes suddenly.
Dynamic PID Control: Includes advanced PID for maintaining constant pressure or flow, featuring "anti-windup" logic to prevent system surges during startup.
Multi-Frequency Control: It can follow multiple speed references simultaneously, which is ideal for complex winding or tension-control machinery.
Safety & Maintenance
Removable Control Terminals: The entire control wiring block is detachable. If you need to swap a drive, you can simply unplug the terminal block and plug it into the new unitno re-wiring required.
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 so you can avoid unplanned downtime.
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.
Connectivity
Standard Modbus RTU & CANopen: Built-in for networking.
Expandable: Unlike the Mini/Micro, the Ace can accept optional cards for Profibus, DeviceNet, Ethernet/IP, and Profinet to fit into any modern factory network.
