Standard Selection Procedure for Schneider Inverter Drives

(Industrial general‑purpose, for sales / cotação / design)

1. Define Application & Série

General industrial machinery: compressores, transportadores, mixers → ATV71 series (alto desempenho, high dynamics)

Fãs / Pumps / AVAC: ar condicionado, water supply, ventilation → ATV61 series (dedicated algorithm, energy saving)

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

2. Determine Load Category

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

Motor load (AC‑3): squirrel‑cage motor DOL → motor current ≤ drive rated current

Shock load (AC‑4): trituradores, presses → select HD series for 150% sobrecarga

3. Calculate Current & Avaliação
4. Read motor nameplate: poder / voltage → rated current
5. Apply 1.1–1.25 safety margin (irrupção, continuous duty)
6. Select rated power / current from Schneider catalog

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

4. Select Voltage Class

200–240 V single/three‑phase: equipamento pequeno

380–480 V three‑phase: industrial standard

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