4. Instal·lació
4.1 Muntatge
The FC280 drive should be mounted vertically on a flat, stable surface in an environment that meets the specified operating conditions (temperature, humidity, ventilation). Ensure adequate clearance around the unit for proper airflow and heat dissipation.
- Mount the drive in an upright position.
- Allow at least 10 cm (4 inches) of free space above and below the unit for ventilation.
- Use appropriate screws and mounting hardware suitable for the drive's weight and the mounting surface.
4.2 Cablejat
All wiring must be performed by a qualified electrician in accordance with local and national electrical codes. Incorrect wiring can cause damage to the drive, motor, or pose a safety hazard.
- Cablejat d'alimentació: Connect the 3-phase 400V AC input power to the L1, L2, L3 terminals. Ensure correct phase sequence.
- Cablejat del motor: Connect the motor leads to the U, V, W output terminals.
- Posada a terra: Connect the protective earth (PE) terminal of the drive to a reliable ground point.
- Cablejat de control: Connect control signals (e.g., start/stop, speed reference) to the appropriate control terminals as per your application requirements. Refer to the detailed wiring diagrams in the full product manual for specific terminal assignments.
5. Configuració i configuració inicials
After successful installation and wiring, the drive requires initial setup. The FC280 features a user-friendly control panel for parameter adjustment.
- Encès: Apply main power to the drive. The display on the control panel should illuminate.
- Basic Parameter Setting:
- Navegueu pel menú amb les tecles de fletxa.
- Set motor nominal voltage (p. ex., 400 V).
- Set motor nominal current.
- Set motor nominal frequency (e.g., 50Hz or 60Hz).
- Set motor nominal speed.
- Configure acceleration and deceleration ramps.
- Motor Auto-Tune (Optional but Recommended): For optimal performance, perform a motor auto-tune function if available in the drive's menu. This process measures motor parameters and optimizes the drive's control algorithms.
- Desa la configuració: Ensure all configured parameters are saved before exiting the setup menu.
6. Instruccions de funcionament
The Danfoss FC280 Inverter Drive can be operated via its local control panel or external control signals.
6.1 Local Operation (Control Panel)
