Emergency

What does F14.12 mean?

Encoder 2 has transmitted an emergency error message, indicating a critical internal or communication issue requiring immediate attention. This is often triggered by severe interference or incorrect communication parameters, leading to loss of position control.

• Internal hardware fault within Encoder 2 causing it to signal a critical error (e.g., ASIC failure, sensor malfunction).
• Severe electromagnetic interference (EMI) corrupting Encoder 2's internal operation or its communication with the controller.
• Incorrect or unstable power supply to Encoder 2 (e.g., excessive ripple) leading to internal logic errors.
• Communication protocol violation or severe misconfiguration (e.g., P6-01 Encoder type mismatch) causing the encoder to enter an error state.
• Over-temperature condition detected by Encoder 2's internal thermal sensor, triggering an emergency shutdown.

Click steps to track your progress.

1. 1

   Power cycle the entire system (drive and Encoder 2) to attempt a full reset of both components.

2. 2

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

3. 3

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

4. 4

   Temporarily disable high-frequency noise sources (e.g., contactors, switching power supplies) near the encoder cable to isolate EMI.

5. 5

   Check for any excessive heat buildup around Encoder 2 housing using a thermal camera or contact thermometer.
