ABNORMAL PHASE (EXT)

Hva betyr SV0381 ?

An abnormal alarm in the position data occurred on the separate linear scale. This indicates an issue with the phase signal generation or detection from the external linear scale.

• Signal degradation or noise affecting the phase signals of the external linear scale.
• Physical damage or contamination on the external scale's reading head.
• Malfunction in the external scale's signal generation circuitry.
• Incorrect installation of the external scale, causing phase shift.
• Encoder signal processing fault within the servo drive.

1. 1

   Clean the external scale's reading head and scale surface.

2. 2

   Measure phase signal levels from the external scale's output terminals.

3. 3

   Verify correct installation and alignment of the external scale.

4. 4

   Check servo parameter P1-04 (External Encoder Type) for correct selection.

5. 5

   Inspect external scale for any visible damage to the track or head.
