Track Measurement Fault (Encoder 1)

What does 13.4 mean?

A fault has been detected during the track measurement process of Encoder 1, indicating issues with the encoder's ability to accurately track movement. This can result in inaccurate position feedback and unreliable drive operation. Continued use with this fault can lead to positioning inaccuracies or uncontrolled movements.

• Degradation of the encoder's optical or magnetic sensor, leading to intermittent signal loss during movement.
• Excessive vibration or mechanical play in the encoder coupling, causing inconsistent track signals.
• Accumulation of dirt, dust, or oil on the encoder's optical disk, interfering with track reading.
• Faulty encoder cable, causing intermittent loss of A, B, or Z phase signals during rotation.
• Internal processing error within the drive's encoder evaluation hardware causing incorrect track interpretation.

Click steps to track your progress.

1. 1

   Monitor the raw encoder signals (e.g., P7-04, A/B/Z pulse count) for any irregular drops or spikes during rotation.

2. 2

   Physically inspect the encoder for signs of contamination (e.g., dust on optical encoder disk) and clean if necessary with approved methods.

3. 3

   Check the mechanical coupling between the motor shaft and the encoder for looseness or excessive runout (measure with dial indicator).

4. 4

   Verify the continuity of individual encoder signal lines (A, /A, B, /B, Z, /Z) in the cable using a multimeter.

5. 5

   Perform a slow, controlled rotation of the motor and observe the encoder position feedback for smoothness and consistency using a diagnostic tool.
