"TP4A" AI4 Thermal warning in Schneider ATV610 drive indicates a thermal overload condition on the Analog Input (AI) 4.

The "TP4A AI4 Thermal warning" in Schneider ATV610 drive indicates a thermal issue related to the analog input AI4. This warning typically suggests that the temperature sensor or thermal protection connected to the AI4 input has detected an abnormal temperature condition.

Steps to Troubleshoot and Resolve "TP4A AI4 Thermal Warning":

  1. Identify the Connected Sensor:

    • Determine what type of sensor or device is connected to the AI4 input. It could be a thermal sensor or another device monitoring temperature.
  2. Check the Sensor:

    • Ensure that the sensor is functioning correctly. Inspect it for any signs of damage or malfunction.
  3. Verify Connections:

    • Check the wiring and connections to the AI4 input. Ensure there are no loose or damaged wires.
  4. Measure the Temperature:

    • If possible, measure the temperature being monitored by the sensor to see if it is within the expected range. Compare this with the drive's parameter settings.
  5. Review Parameter Settings:

    • Verify the configuration of the AI4 input parameters. Ensure that the correct type of sensor is selected and that all related parameters (such as scaling, thresholds, and limits) are set correctly.
    • Specifically, check parameters related to the AI4 input, such as the type of sensor (e.g., thermistor, RTD) and the scaling settings.
