AMA Internal fault (Advanced)

What does 58 mean?

An internal fault occurred during the Automatic Motor Adaptation (AMA) process that requires expert intervention. This indicates a more complex problem within the drive's control logic or measurement system during motor characterization. It cannot be resolved by simple restart and requires deeper diagnosis.

• Hardware malfunction on the drive's control or power board impacting critical internal measurements for AMA (e.g., DSP calculation error).
• Deep-seated firmware error or corruption that is not resolved by a simple power cycle or parameter initialization.
• Failure within the motor control feedback loop that prevents accurate and stable parameter identification during AMA.
• Over-current or over-voltage event during the AMA process that triggered an internal protection circuit or caused component damage.
• A unique combination of motor characteristics and drive ratings pushing the AMA algorithm into an unhandled state.

Click steps to track your progress.

1. 1

   Document the exact drive model, firmware version, and all motor parameters (P1-20 through P1-24) for detailed technical support.

2. 2

   Attempt a factory reset (P14-22 Load Parameters) and manually re-enter all parameters, then retry AMA.

3. 3

   Thoroughly review the drive's event log (P15-30 Fault Log) for any diagnostic codes or other faults preceding this advanced internal fault.

4. 4

   Verify the integrity of the drive's main power supply connections and ensure stable input voltage levels.

5. 5

   Contact the drive manufacturer's technical support with comprehensive fault information for advanced diagnostics or potential repair authorization.
