Internal fault

What does F14.23 mean?

Encoder 2 is reporting an internal fault status, indicating a malfunction within the encoder hardware or software. This compromises the accuracy and reliability of position feedback, potentially causing drive control issues.

• Minor hardware anomaly within Encoder 2, such as a failing internal diagnostic circuit or transient memory error.
• Intermittent power supply instability to Encoder 2, causing its internal self-monitoring system to trigger a non-critical fault.
• Degradation of internal optical or magnetic components within Encoder 2 over time, leading to reduced signal quality.
• Firmware integrity issue within Encoder 2, potentially due to an interrupted update or corrupted memory segment.

Click steps to track your progress.

1. 1

   Measure the supply voltage to Encoder 2 at its input terminals (e.g., +10V to 0V or +24V to 0V) for stability and correct level.

2. 2

   Cycle power to the drive and Encoder 2, then observe if the internal fault clears upon restart.

3. 3

   Check for any documented firmware updates for Encoder 2 that address known internal fault conditions.

4. 4

   Monitor the ambient temperature around Encoder 2 to ensure it is operating within its specified temperature range.

5. 5

   If accessible, perform an internal diagnostic check on Encoder 2 using manufacturer-specific software or tools.
