Encoder internal

What does 7380 mean?

An internal fault has occurred within the encoder system itself, indicating a problem with the encoder's electronics or processing. This is a critical fault preventing accurate speed/position feedback, rendering closed-loop control impossible. This typically requires specialized assistance.

• Encoder's internal electronics malfunction or processing unit failure.
• Corrupted firmware within the smart encoder (e.g., Hiperface, EnDat) requiring a firmware update.
• Unstable power supply to the encoder causing intermittent operation (e.g., ripple on 5VDC or 15VDC supply).
• Communication bus error between the drive and smart encoder (e.g., corrupted data packets on the serial interface).
• Encoder overheating due to environmental conditions, restricted airflow, or internal component failure.

Click steps to track your progress.

1. 1

   Power cycle the drive and encoder system to attempt a reset of the internal encoder electronics.

2. 2

   Check the encoder's own status LEDs (if available) for specific error indications (e.g., green/red status).

3. 3

   Verify stable 5VDC or 15VDC power supply to the encoder at the encoder connector (e.g., pins 1 and 2) with an oscilloscope.

4. 4

   Inspect the encoder communication cable (e.g., Ethernet, RS485) for physical damage or loose connections.

5. 5

   If the fault persists after basic checks, the encoder itself is likely faulty and requires replacement.
