An internal fault indicating an overflow in a 32-bit text table within the drive's memory. This typically points to an internal software anomaly or a memory management issue. If unaddressed, it could lead to unpredictable drive behavior or further system faults.
Click steps to track your progress.
Record all active faults and warnings from the drive's event log for diagnostic purposes.
Perform a power cycle of the drive to clear transient memory states.
If the fault persists, attempt a parameter reset to factory defaults (P96-01=1) and then restore parameters from a known good backup.
Update the drive's main firmware to the latest available version from the manufacturer's website.
If updating firmware does not resolve the issue, consider replacing the drive's main control board as a hardware memory issue may be present.
