PwrDnEntry2Large

¿Qué significa 116 ?

An internal data error indicates that a power-down entry is too large. This implies an issue with data structure integrity in the non-volatile memory, specifically concerning entries related to power-down state saving. Such errors can lead to data corruption or incorrect drive state restoration upon power-up.

• Corruption of the data structure for a power-down event in non-volatile memory (NVS).
• Firmware bug attempting to write an excessively large or malformed entry to the power-down table.
• Internal non-volatile memory (NVS) hardware fault affecting specific write operations to the power-down table.
• Interrupted write operation during a power-down event, leaving a fragmented or oversized entry.
• Incompatibility between firmware versions and the expected NVS data structure for power-down entries.

1. 1

   1. Perform a factory reset of drive parameters (e.g., P0-01 to "Factory Reset") to clear internal data structures and reset NVS.

2. 2

   2. Upload a known good parameter set from a backup file to overwrite any corrupted NVS entries.

3. 3

   3. Verify the stability of the main control board's (MCB) control voltage (e.g., 24VDC) to ensure reliable NVS write operations.

4. 4

   4. Check for and install any available firmware updates for the main control board (MCB) that may contain fixes for NVS handling.

5. 5

   5. If the fault persists, the main control board (MCB) is likely defective due to non-volatile memory corruption and should be replaced.
