| Fattore | Matching Standard | Risk of Mismatch |
| Potenza nominale | Rated current ≥ original model, power deviation ≤ ±5% | Overload protection failure, module burnout |
| Metodo di controllo | At least equivalent to the original model (Vector→Vector, V/f→V/f) | Performance degradation, insufficient control precision |
| Valutazione della tensione | Input/output voltage completely consistent (380V/400V/690V) | Insulation breakdown, equipment damage |
- Key Parameter Checklist
- Capacità di sovraccarico: Must be ≥150%/60s for heavy-duty applications, ≥120%/60s for general loads
- Classe di protezione: Select IP20 (indoor cabinet)/IP54 (all'aperto)/IP66 (underwater) as required
- Protocollo di comunicazione: Modbus/Profibus/Profinet/EtherNet/IP must be compatible with the system
- Dimensioni di installazione: Ensure consistent rail/panel mounting holes during replacement to avoid re-drilling
- Compatibilità degli accessori: Braking units, filtri, and reactors must match the parameters of the new frequency converter
