The Fuji Electric FRN0018C2S-4A (FRENIC-Mini C2) is a high-power compact drive designed for 7.5kW (10 HP) motors. With a rated output of 18.0 Amps, it is built to handle heavy industrial machinery that requires both high torque and precise speed management.
Primary Control Functions
Maximum Heavy-Duty Torque: Uses Dynamic Torque Vector Control to deliver 150% torque at 1Hz. This is essential for 10 HP motors starting under massive loads, such as stone crushers, large mixers, or fully loaded belt conveyors.
Dual Motor Support: It can control both standard Induction Motors and high-efficiency Permanent Magnet (PM) Synchronous Motors. This allows you to upgrade your motor to a more energy-efficient model without needing to buy a new drive.
Integrated Braking Chopper: Comes with a built-in braking transistor. For 10 HP high-inertia loads (like massive industrial fans or centrifuges), this allows you to stop the motor quickly by connecting an external braking resistor.
Operational Capabilities
Advanced PID Control: Includes a built-in PID regulator with "Sleep" and "Wake-up" modes. This is perfect for 10 HP water pump systems or air compressors, where the drive automatically stops when pressure is met and restarts when demand increases.
Soft Start/Stop (S-Curve): You can program smooth "S-curve" acceleration and deceleration to prevent mechanical shock to gears, belts, and couplings, which is critical for the longevity of a 10 HP system.
8-Step Multi-Speed: Supports up to 8 pre-programmed speeds that can be triggered by external sensors or a PLC for automated production cycles.
Automatic Energy Saving: Even at this power level, the drive optimizes the motor's magnetic flux during light-load operation to minimize electricity costs.
Safety & Maintenance
Component Life Diagnostics: The drive monitors its own internal "health." It can signal a warning when the cooling fan or DC bus capacitors reach 90% of their expected 10-year lifespan, helping you avoid unexpected factory downtime.
Sophisticated Motor Protection: The electronic thermal relay is specifically calibrated for 7.5kW motors, monitoring current profiles to prevent winding burnout without needing external thermal relays.
Trip History: Records detailed logs (Amps, Volts, Frequency) of the last several faults, allowing maintenance teams to quickly diagnose if a problem was caused by a mechanical jam or a power surge.
Interface & Connectivity
Built-in Potentiometer: Features a physical dial on the keypad for intuitive, manual speed control.
RS-485 Modbus RTU: Standard communication port for connecting to HMI touchscreens, SCADA systems, or factory-wide PLC networks.
FRENIC Loader Support: Can be connected to a PC for fast parameter editing, monitoring, and backup via a USB adapter.
