Standard Selection Procedure for Schneider Inverter Drives

(Industrial general‑purpose, per le vendite / preventivo / progetto)

1. Definire l'applicazione & Serie

General industrial machinery: compressori, trasportatori, mixers → ATV71 series (alte prestazioni, high dynamics)

Tifosi / Pumps / HVAC: aria condizionata, water supply, ventilation → ATV61 series (dedicated algorithm, risparmio energetico)

Complex motion control: gru, ascensori, precision machinery → ATV900 series (high‑end, multi‑axis synchronization)

2. Determinare la categoria di carico

Continuous load (AC‑1): riscaldatori, lighting → 1:1 power selection

Carico del motore (AC‑3): squirrel‑cage motor DOL → motor current ≤ drive rated current

Shock load (AC-4): frantoi, presses → select HD series for 150% sovraccarico

3. Calculate Current & Valutazione
4. Read motor nameplate: energia / voltage → rated current
5. Apply 1.1–1.25 safety margin (spunto, servizio continuo)
6. Select rated power / current from Schneider catalog

Esempio: 380 V three‑phase 15 kW motor ≈ 30 A → ATV71HD15N4Z (48 UN) is suitable.

4. Select Voltage Class

200–240 V single/three‑phase: small equipment

380–480 V three‑phase: industrial standard

525–690 V three‑phase: high‑voltage systems

5. Define Control & Comunicazione
