VI. Typical Application Parameter Configuration Examples

VII. Precautions 1. **Motor Compatibility**   - **Asynchronous Motor**: Directly supported, and parameters P0304-P0311 need to be set correctly.   - **Synchronous Motor**: Theoretically, it can be driven by setting P1300=3, but Siemens does not recommend this application. 2. **Braking Resistor Selection**   - The continuous working cycle should be ≤5%, otherwise, a resistor with a larger power needs to be selected (such as 6SE3201-0BE14-3AA0, 27Ω/1.2kW). 3. **Communication Interference**   - For RS485, a twisted-pair shielded cable should be used, and the terminal resistor is 120Ω (needs to be external). 4. **Parameter Backup**   - It is recommended to regularly back up parameters through the BOP panel or the smart connection module to prevent accidental loss.
