The PROFIBUS address configured for the drive is incorrect at startup, either due to an improper DIP switch setting or an incorrect value in parameter P0918. This prevents the drive from communicating correctly on the PROFIBUS network, leading to a loss of control from the PROFIBUS master.
Click steps to track your progress.
1. Check the physical DIP switch settings on the PROFIBUS module (if present) and ensure they correspond to the desired PROFIBUS address.
2. Verify parameter P0918 (PROFIBUS address) in the drive and ensure it precisely matches the address configured in the PROFIBUS master's hardware configuration.
3. Review the PROFIBUS network's address map to confirm no other device is assigned the same address as the drive.
4. Perform a factory reset of communication parameters (e.g., P0010=30, P0970=1) and then reconfigure P0918 to ensure correct storage.
5. Cycle power to the drive and observe the PROFIBUS status LEDs (e.g., BF) during startup for address recognition status.
