Hardware Reconfiguration Request

What does FF38 mean?

The inverter type (e.g., sr0025_3) has been changed, typically at the factory or during drive implementation. This fault indicates that the new configuration needs to be validated before the drive can operate correctly, requiring a specific power-off sequence.

• Drive control board or power module replaced with a different model or firmware version.
• Firmware update initiated but not fully validated or a mismatch detected.
• Parameter backup/restore operation performed with a file from a different drive model or configuration.
• Corruption of internal drive configuration memory requiring reinitialization.
• Installation of an incompatible option card (e.g., I/O extension, communication module).

Click steps to track your progress.

1. 1

   Confirm the model and firmware version of the installed control board and power module match the original specification.

2. 2

   Perform a factory reset (e.g., P99-01 = 1) and then re-enter or reload parameters from a known good backup file.

3. 3

   Verify all installed option cards (e.g., fieldbus module, I/O extension) are compatible with the drive model and firmware.

4. 4

   Attempt to re-upload the correct firmware using the manufacturer's commissioning tool, ensuring checksum validation passes.

5. 5

   If available, try swapping the control board with a known good, compatible spare, then attempt to power cycle the drive.
