Pointer Parameter Error

What does FFD0 mean?

A source selection (pointer) parameter has been configured to point to a non-existent parameter index. This indicates a configuration error in the drive's settings, which can lead to incorrect parameter referencing and potentially erratic or undefined drive behavior.

• An output reference parameter (e.g., P5-01, P6-02) is configured to point to a non-existent parameter index (e.g., P30-99) within the drive's firmware.
• Manual entry error during parameter configuration, where an invalid numeric parameter index was entered into a pointer-type parameter.
• Loading an old parameter set (backup) from a different drive model or firmware version that has distinct parameter mapping, leading to invalid pointers.
• Corruption of the drive's internal parameter memory, resulting in an invalid or out-of-range pointer address being stored.
• Specific feature or parameter associated with the pointer was removed or re-indexed in a firmware update, rendering existing pointers invalid.

Click steps to track your progress.

1. 1

   Identify the specific pointer parameter (e.g., P5-01) causing the error from the drive's fault log or diagnostic screen.

2. 2

   Access the identified pointer parameter (e.g., P5-01) and verify its configured value, which represents the target parameter index.

3. 3

   Cross-reference the target parameter index (e.g., 3099) with the drive's current parameter manual to confirm its existence and validity for the installed firmware.

4. 4

   If the target parameter index is invalid, reset the pointer parameter (e.g., P5-01) to a known valid index (e.g., 0 for no selection) or a valid, existing parameter (e.g., P3-01 for Analog Input 1).

5. 5

   If the parameter set was loaded from a backup, verify the drive model and firmware version of the source backup match the current drive's specifications (e.g., displayed via P0-03).

6. 6

   Perform a factory reset of the drive (e.g., using parameter P0-99 set to 1) and meticulously reconfigure essential parameters, paying close attention to all pointer parameter settings.
