4. Instalace
4.1 Montáž
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 Zapojení
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.
- Napájení: Connect the 3-phase 400V AC input power to the L1, L2, L3 terminals. Ensure correct phase sequence.
- Zapojení motoru: Connect the motor leads to the U, V, W output terminals.
- Základy: Připojte ochrannou uzemňovací svorku (PE) měniče ke spolehlivému uzemňovacímu bodu.
- Zapojení ovládání: 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. Počáteční nastavení a konfigurace
After successful installation and wiring, the drive requires initial setup. The FC280 features a user-friendly control panel for parameter adjustment.
- Zapnutí: Apply main power to the drive. The display on the control panel should illuminate.
- Basic Parameter Setting:
- Procházejte nabídku pomocí kláves se šipkami.
- Set motor nominal voltage (např. 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.
- Uložit nastavení: Ensure all configured parameters are saved before exiting the setup menu.
