1. Core Philosophy of the FC-302 Series

The FC-302 series bridges the gap between standard variable-frequency drives and advanced motion controllers, offering:

• Adaptive Motor Control: Supports asynchronous motors, permanent magnet synchronous motors (PMSM), and direct-on-line PMSM via sensorless vector control (VVC+™) and closed-loop vector modes.

• Modular Expandability: Plug-and-play options for I/O expansion, communication protocols, and safety features.

• Thermal Resilience: Operates at -25°C to +50°C without derating due to advanced cooling designs (forced convection or back-channel cooling).

• Integrated Intelligence: Embedded Smart Logic Controller reduces PLC dependency for basic sequencing and PID control.

3. Technical Specifications & Key Features

A. Electrical Performance

• Output: 2.2 kW (3.0 HP) continuous, ~6 A output current.

• Control Accuracy: ±0.1% speed regulation in VVC+™ mode without encoder feedback.

• Overload Capacity: 150% for 3 sec / 110% for 60 sec.

• Frequency Range: 0–500 Hz for wide-speed applications.

B. Safety & Compliance

• STO (Safe Torque Off): Prevents unintended motor activation via safety relays (terminals 37/38), meeting EN/IEC 61800-5-27.

• RFI Mitigation: Dual-class filter (A1/B) minimizes electromagnetic interference in sensitive environments.

C. Thermal Management & Robustness

• Cooling System: Forced-air convection over aluminum heatsinks isolates electronics from contaminants.

• Environmental Suitability: Operates in -25°C to +50°C without derating – critical for industrial HVAC and material handling.

D. User Interface & Connectivity

• Local Control Panel (LCP): Basic display for parameter access; supports hot-swapping for cloning settings.

• PROFIBUS DP Integration: Enables real-time PLC communication for centralized monitoring/control.

E. Option C4: Critical Add-On

The C4 suffix denotes a factory-installed option, likely the MCB-107 24V DC Backup Power module1. This ensures:

• Continuous operation during mains power fluctuations.

• Safe shutdown sequences in critical processes.

4. Key Design Advantages

• Back-Channel Cooling: Isolates cooling air from electronics, reducing cabinet size/cost.

• DrivePro® Services: Predictive tools monitor capacitor aging, fan health, and thermal stress to extend service life.

• Auto Energy Optimization (AEO): Reduces energy consumption by 5–15% via dynamic voltage adjustment.

5. Operational Implications & Limitations

• No Brake Chopper: Requires external module for dynamic braking in high-inertia applications (e.g., conveyors, centrifuges).

• No Conformal Coating: Unsuitable for humid/corrosive environments; necessitates climate-controlled cabinets.

• IP20 Enclosure: Mandates installation in ≥IP54 cabinets for dust/liquid protection.

6. Target Applications

This model excels in protected industrial automation settings:

• Material Handling: Conveyor speed synchronization, palletizers.

• Pump & Fan Control: HVAC circulation, pressure boosting with built-in PID.

• Safety-Critical Systems: STO-compliant machinery (e.g., automated assembly lines).

• Cost-Sensitive OEM Designs: Compact A2 frame reduces panel space; PROFIBUS DP slashes wiring costs.

7. Comparative Advantage in Industry

• Reduced Downtime: Modular design allows swift component replacement; DrivePro® Retrofit service extends lifecycle.

• Regulatory Compliance: Meets IEC/EN 61800-3 (EMC), EN 954-1 (Safety), and EU machinery directives.

• Scalability: Optional encoder feedback (MCB-102) upgrades to closed-loop control for servo-like precision.
