PwrDn Table Full

What does 115 mean?

This internal data error indicates that a power-down data table is full. This suggests an overflow or corruption in a system table used for handling power loss events or storing critical state information. This could lead to incorrect drive behavior or state recovery after power cycles.

• Excessive number of power-down events without proper table cleanup by the firmware, leading to an overflow.
• Corruption of the power-down data table structure in non-volatile memory.
• Firmware bug leading to inefficient use or incorrect management of the power-down table.
• Internal non-volatile memory (NVS) hardware fault preventing proper table writes or capacity management.
• Frequent, very short power interruptions that trigger numerous incomplete power-down entries.

Click steps to track your progress.

1. 1

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

2. 2

   2. Check the stability of the incoming AC supply voltage (e.g., L1-L2-L3) for intermittent sags or drops using a power quality analyzer.

3. 3

   3. Verify the ride-through capabilities of the drive are adequate for the application (e.g., parameter P0-11 for voltage sag ride-through time).

4. 4

   4. Ensure proper grounding and electromagnetic interference (EMI) suppression measures are in place according to installation guidelines (e.g., shielded cables).

5. 5

   5. If the fault recurs, consider updating the main control board firmware or replacing the main control board if non-volatile memory corruption is suspected.
