COUNT MISS(EXT)

What does 382 mean?

This alarm on Fanuc Series 0i-D/0i Mate-D indicates a position data count error from a separate (external) detector. This is typically due to a detector failure, signal corruption, or mechanical issues.

• Internal failure of the external detector resulting in incorrect pulse counting.
• Damaged or loose cable leading to intermittent signal loss from the external detector.
• Excessive vibration or mechanical play affecting the external detector's accuracy.

Click steps to track your progress.

1. 1

   Inspect the external detector's cable and connectors for proper seating, damage, or loose connections.

2. 2

   Verify the mechanical mounting of the external detector for stability and correct alignment.

3. 3

   Check for any excessive vibration or mechanical play in the system that could cause counting errors.

4. 4

   If physical inspection and mechanical checks do not resolve the issue, replace the external detector unit.
