DATA TRANS. ERROR(EXT)

Hva betyr SV0386 ?

A CRC error or stop bit error occurred in the communications data from the standalone detector. This signifies data corruption or an improper termination in the serial communication from the external detector.

• Noise or data corruption on serial communication lines from the external detector.
• External detector hardware malfunction leading to data errors.
• Faulty CRC or stop bit generation in the external detector's firmware.
• Damaged serial receiving interface on the servo drive.
• Incorrect serial communication protocol settings.

1. 1

   Measure signal quality and waveform on serial data lines from external detector.

2. 2

   Ensure proper shielding and grounding of all communication cables.

3. 3

   Verify servo parameter P1-03 (Encoder Serial Protocol) selection.

4. 4

   Use a logic analyzer to examine serial data frames for errors.

5. 5

   Swap communication cables to rule out cable faults.
