DATA TRANS. ERROR(INT)

What does SV0369 mean?

A CRC error or stop bit error occurred in the communications data from the built-in Pulsecoder. This signifies data corruption or an improper termination in the serial communication from the internal encoder.

• Noise or interference corrupting serial data packets from the internal Pulsecoder.
• Internal Pulsecoder hardware fault causing data corruption.
• CRC calculation error within the internal Pulsecoder's firmware.
• Damaged serial interface on the servo drive receiving data.
• Incorrect stop bit configuration in communication parameters.

Click steps to track your progress.

1. 1

   Measure signal integrity of serial data lines (e.g., clock, data) from internal Pulsecoder.

2. 2

   Ensure proper grounding of the servo drive and internal Pulsecoder.

3. 3

   Check servo parameter P1-03 (Encoder Serial Protocol) for correct configuration.

4. 4

   Use an oscilloscope to analyze serial data frames for errors.

5. 5

   Swap communication cables to rule out cable degradation.
