- Fonctions de contrôle: For fan/pump applications, prioritize models with PID, sleep/wake-up, multi-pump control
- Compatibilité d'installation: Match dimensions, cutout, cooling requirements with original equipment
- Migration des paramètres: ATV930/630 support direct parameter import from ATV71, reducing commissioning cost
- Capacité de surcharge: ATV71: 150% overload for 60s; verify equivalent rating when replacing
- Recommandations de sélection
Prioritize Schneider official upgraded models (ATV930/630): best compatibility, full technical support
HVAC fan/pump applications: Choose HU type first, then brand-specific HVAC-optimized drives (par ex., ABB ACS580-01, Siemens G120X)
General industrial applications: HD type or general vector inverters; verify braking unit, EMC filter options
