Analog input 2 fault

Was bedeutet 28802 ?

The monitoring function for analog input 2 has been triggered, as configured via parameters 0x2637:008 (P431.08) and 0x2637:009 (P431.09). This indicates an issue with the signal connected to analog input 2, potentially an out-of-range or missing signal.

• Analog input signal from the external device connected to Analog Input 2 is outside the configured monitoring range (P431.08, P431.09).
• Cable fault (open circuit or short circuit) in the wiring connected to Analog Input 2, resulting in an invalid signal level.
• Malfunctioning external sensor (e.g., potentiometer, temperature probe) providing an out-of-specification signal.
• Misconfiguration of the monitoring thresholds in parameters 0x2637:008 (P431.08) and 0x2637:009 (P431.09).
• Electromagnetic interference (EMI) or ground loop issues affecting the signal integrity on Analog Input 2.

1. 1

   Measure the actual signal voltage or current at the Analog Input 2 terminals (e.g., X3.3, X3.4) to confirm its value.

2. 2

   Check the output of the sensor or transducer connected to Analog Input 2 directly at its terminals for expected signal levels.

3. 3

   Verify the wiring continuity and shielding from the sensor to Analog Input 2 for damage or loose connections.

4. 4

   Review parameters 0x2637:008 (P431.08) and 0x2637:009 (P431.09) to ensure they are appropriate for the expected signal range.

5. 5

   Disconnect the external signal and apply a known test voltage or current to Analog Input 2 to check the drive's input circuit functionality.
