| 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 |
| Voltage Rating | Input/output voltage completely consistent (380V/400V/690V) | Insulation breakdown, equipment damage |
- Key Parameter Checklist
- 過負荷容量: Must be ≥150%/60s for heavy-duty applications, ≥120%/60s for general loads
- Protection Class: Select IP20 (indoor cabinet)/IP54 (outdoor)/IP66 (underwater) as required
- 通信プロトコル: 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
- Recommended Common Replacement Combinations
| Original Brand Series | Recommended Replacement Brand Series | Replacement Advantages |
| Siemens V20 | ABB ACS150/Schneider ATV320 | Lower price, equivalent functions |
