Standard Selection Procedure for Schneider Inverter Drives

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

1. Define Application & Série

General industrial machinery: compresseurs, convoyeurs, mixers → ATV71 series (haute performance, high dynamics)

Ventilateurs / Pumps / CVC: climatisation, water supply, ventilation → ATV61 series (dedicated algorithm, économie d'énergie)

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

2. Determine Load Category

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

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

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

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

Exemple: 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: norme industrielle

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

5. Define Control & Communication
6. Control method:

General: standard flux vector control

High precision: closed‑loop vector with encoder

2. Communication:

Standard: Modbus RTU

Facultatif: CANopen, Profibus-DP, EtherNet/IP

3. IHM:

No terminal: model ends with Z

Graphical terminal: model ends with N4
