Core Functions

Dynamic Torque Vector Control: Delivers stable starting torque of 150% or more at 1Hz, ensuring smooth startups for heavy mechanical loads.
Permanent Magnet (PM) Motor Support: Unlike basic drives, this series is compatible with energy-efficient Synchronous PM motors as well as standard induction motors.
Advanced PID Logic: Includes built-in PID control with "Sleep" and "Wake-up" modes, ideal for maintaining constant pressure in 20 HP pumping systems.
Predictive Maintenance: Monitors the remaining life of cooling fans and capacitors, alerting you before a failure occurs to prevent downtime.

The Fuji Electric FRN0030C2S-4A (FRENIC-Mini C2) is a high-capacity 15 kW (20 HP) drive. Handling 30.0 Amps, it is built to manage large-scale industrial motors where power, reliability, and precision are critical.

Primary Control Functions

Massive Torque at Startup: Uses Dynamic Torque Vector Control to deliver 150% torque at 1Hz (and up to 200% for brief moments). This ensures that heavy 20 HP loadslike large industrial mixers, stone crushers, or fully loaded uphill conveyorsstart smoothly without stalling.
Universal Motor Compatibility: It can control both standard Induction Motors and high-efficiency Permanent Magnet (PM) Synchronous Motors. This allows you to future-proof your facility for the latest energy-saving motor technologies.
Standard Braking Chopper: Includes a built-in braking transistor. For 20 HP high-inertia loads (like massive industrial blowers or centrifuges), this allows for rapid stopping by adding an external braking resistor.

Operational Capabilities

Intelligent PID Control: Features a built-in PID regulator with "Sleep" and "Wake-up" modes. This is perfect for large-scale constant-pressure water systems or ventilation, where the drive automatically shuts down during zero demand and restarts when needed.
Soft Start/Stop (S-Curve): You can program smooth "S-curve" acceleration and deceleration ramps to prevent mechanical stress on gears, belts, and couplings, which is vital for the longevity of a 20 HP system.
8-Step Multi-Speed: Allows for the programming of up to 8 different speeds that can be triggered by external sensors or a PLC for automated production cycles.
Energy Optimization: Even at this power level, the drive optimizes the motor's magnetic flux during light-load operation to minimize electricity costs.

Safety & Maintenance

Predictive Life Diagnostics: The drive monitors its own internal "health." It can signal a warning when the cooling fans or DC bus capacitors reach 90% of their expected 10-year lifespan, helping you schedule maintenance before an unexpected breakdown.
Advanced Motor Protection: Features a sophisticated electronic thermal relay specifically calibrated for 15kW motors to prevent winding burnout without needing external thermal relays.
Trip History Logging: Records detailed data (Amps, Volts, Frequency) for the last several trip events, which is crucial for troubleshooting mechanical jams in large 20 HP systems.

Interface & Connectivity

Built-in Potentiometer: Features a physical dial on the keypad for intuitive, manual speed control by floor operators.
RS-485 Modbus RTU: Built-in as standard, making it easy to connect the drive to a factory-wide SCADA system or an HMI touchscreen.
FRENIC Loader Support: Can be connected to a PC for fast parameter editing, troubleshooting, and backup via a USB adapter.
