Standard Selection Procedure for Schneider Inverter Drives

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

1. Define Application & シリーズ

General industrial machinery: コンプレッサー, conveyors, mixers → ATV71 series (high performance, high dynamics)

Fans / Pumps / HVAC: air conditioning, water supply, ventilation → ATV61 series (dedicated algorithm, energy saving)

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

2. Determine Load Category

Continuous load (AC-1): heaters, lighting → 1:1 power selection

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

Shock load (AC‑4): crushers, presses → select HD series for 150% 過負荷

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

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

4. Select Voltage Class
