About FRN0004C2S-4A - Fuji Mini 0.4kw 0.5hp 440V

The

Fuji Electric FRN0004C2S-4A

belongs to the FRENIC-Mini (C2) series. While it shares some DNA with the FVR-Micro models you've been asking about, it is part of a more feature-rich "compact" family often used for higher-performance tasks.

Key Technical Specifications

Despite some mixed catalog listings, for the -4A (Asia/Global) model, the official ratings are typically:

Feature	Specification
Model Number	FRN0004C2S-4A
Applicable Motor	0.75 kW (1.0 HP)
Rated Output Current	3.1 A (Standard) / 2.5 A (Low Carrier)
Input Voltage	3-Phase 380V to 480V AC
Efficiency	Approximately 96%
Overload Capacity	150% for 1 minute; 200% for 0.5 seconds

Dimensions & Weight (Inches)

The FRENIC-Mini C2 series uses a slightly different chassis than the FVR-Micro.

Measurement	Metric	Imperial (Inches/Lbs)
Width	110 mm	4.33 in
Height	130 mm	5.12 in
Depth (Length)	139 mm	5.47 in
Weight	1.3 kg	2.87 lbs

Core Functions

Dynamic Torque Vector Control: Unlike basic V/F drives, this series uses Fuji's proprietary control to ensure stable torque even at extremely low speeds, making it ideal for heavy-start conveyor belts.
Permanent Magnet (PM) Motor Support: This drive is versatile enough to control both standard induction motors and more modern synchronous PM motors.
Built-in Braking Chopper: Includes a dedicated braking circuit as standard, allowing for faster deceleration of high-inertia loads without extra external modules.
RS-485 Modbus RTU: Comes standard with communication ports for remote networking.

The Fuji Electric FRN0004C2S-4A (FRENIC-Mini C2) is a high-performance compact drive. While it performs the same basic job as the "Micro" series, it has "smarter" software and more robust hardware for handling difficult loads.

Primary Control Functions

Dynamic Torque Vector Control: This is Fujis signature feature. It doesn't just send a fixed voltage; it calculates the exact power needed to keep the motor spinning at the right speed, even if the load changes suddenly. It provides 200% starting torque at 0.5Hz.
PM Motor Control: Unlike basic VFDs, this unit can control Permanent Magnet (PM) Synchronous Motors in addition to standard induction motors, which is great for high-efficiency setups.
Built-in Braking Transistor: It has a "chopper" circuit built-in. This allows the drive to stop heavy, spinning loads much faster by burning off the extra energy through a resistor (optional add-on).

Operational Capabilities

Full PID Control: It can manage a closed-loop system (like maintaining constant water pressure in a pipe) using a feedback sensor, without needing a separate PLC.
Multi-Speed & Pattern Operation: You can program it to run through a sequence of different speeds and directions automatically.
Overload "Ride-Through": If the motor hits a temporary mechanical jam, the drive tries to "power through" by boosting current briefly instead of just tripping immediately.
Energy Saving Mode: It automatically reduces the magnetic flux in the motor during light loads to save electricity.

Safety & Protection

Advanced Diagnostics: It monitors its own "health," including the remaining life of the internal capacitors and the cooling fan, and gives you a warning before they fail.
Comprehensive Fault Protection: Protects against overcurrent, overvoltage, motor stalling, and ground faults.
Stall Prevention: Automatically adjusts frequency during acceleration or heavy load spikes to prevent the drive from "tripping out."

Interface & Networking

USB Port Support: You can connect it to a PC using an optional adapter to program all settings via Fujis "FRENIC Loader" software.
RS-485 Communication: Full Modbus RTU support is standard, allowing it to talk to touchscreens (HMIs) and PLCs.
User-Friendly Keypad: Features a built-in speed pot (dial) and a display that can show output frequency, motor speed, or output current.
