Standard Selection Procedure for Schneider Inverter Drives

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

1. Define Application & Series

General industrial machinery: compressors, 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% overload

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

Example: 380 V three‑phase 15 kW motor ≈ 30 A → ATV71HD15N4Z (48 A) 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 & Communication
6. Control method:

General: standard flux vector control

High precision: closed‑loop vector with encoder

2. Communication:

Standard: Modbus RTU

Optional: CANopen, Profibus DP, EtherNet/IP

3. HMI:

No terminal: model ends with Z

Graphical terminal: model ends with N4

6. Special Functios

EMC filter: Category A (built‑in) or B (optional)

Brake unit: built‑in (standard) or external (high power)

Safety: STO (Safe Torque Off) available

Extended I/O via option cards

7. Environment & Mounting

Temperature > 40 °C, altitude > 1000 m → derate or upsize

Protection: IP20 for cabinet, IP54+ for outdoor

Mounting: 35 mm DIN rail or screws, vertical for cooling

8. Final Check: Model + Certificates
9. Confirm full model: series–power–voltage–option
