Data timeout

What does F14.11 mean?

Encoder 2 has failed to provide process data within the expected timeframe, resulting in a data timeout. This typically points to communication issues caused by electromagnetic interference (EMC) or incorrect startup parameters.

• Intermittent disconnection, open circuit, or damage in the Encoder 2 communication cable.
• Excessive electromagnetic interference (EMI) on the Encoder 2 communication lines disrupting data packet transmission.
• Faulty Encoder 2 hardware failing to generate process data or respond to controller requests.
• Incorrect communication parameters (e.g., baud rate, data length) configured in the drive for Encoder 2.
• Unstable or insufficient power supply to Encoder 2 (e.g., voltage below 20VDC) causing intermittent resets.

Click steps to track your progress.

1. 1

   Inspect Encoder 2 communication cable for physical damage and verify all connections are secure at terminals (e.g., X12).

2. 2

   Measure the supply voltage to Encoder 2 (e.g., between terminals A+ and A-) to confirm it is stable and within specified range (e.g., 24VDC +/-10%).

3. 3

   Check the drive's parameter settings for Encoder 2 communication (e.g., P6-01 Encoder type, P6-02 Data rate).

4. 4

   Verify the cable shielding integrity by checking continuity between the shield and protective earth at the control cabinet.

5. 5

   Temporarily reroute the encoder cable or isolate high-power cables running in parallel to reduce potential EMI sources.
