| Factor | Matching Standard | Risk of Mismatch |
| Power Rating | Rated current ≥ original model, power deviation ≤ ±5% | Overload protection failure, module burnout |
| Control Method | At least equivalent to the original model (Vector→Vector, V/f→V/f) | Performance degradation, insufficient control precision |
| Tensiune nominală | Input/output voltage completely consistent (380V/400V/690V) | Insulation breakdown, equipment damage |
- Key Parameter Checklist
- Capacitate de suprasarcină: Must be ≥150%/60s for heavy-duty applications, ≥120%/60s for general loads
- Clasa de protectie: Select IP20 (indoor cabinet)/IP54 (outdoor)/IP66 (underwater) as required
- Protocolul de comunicare: Modbus/Profibus/Profinet/EtherNet/IP must be compatible with the system
- Installation Dimensions: Ensure consistent rail/panel mounting holes during replacement to avoid re-drilling
- Accessory Compatibility: Braking units, filters, and reactors must match the parameters of the new frequency converter
