H11 (Temperature sensor error: Temperature inside the controller)

¿Qué significa x111 ?

The internal temperature sensor within the controller is reporting undefined values. This compromises the ability of the drive to monitor and protect itself against overheating conditions.

• Internal temperature sensor (e.g., on control board or power board) has failed or become disconnected.
• Intermittent electrical connection to the internal temperature sensor within the drive.
• Faulty analog-to-digital converter (ADC) on the control board failing to read the sensor correctly.
• High ambient temperature exceeding the drive's operational limits, leading to sensor saturation or failure.
• Firmware bug causing incorrect interpretation of the sensor's raw data.

1. 1

   Perform a power cycle to the drive by disconnecting mains power for at least 30 seconds.

2. 2

   Check the ambient temperature around the drive with a thermometer and ensure it is within the manufacturer's specified operating range (e.g., 0-50°C).

3. 3

   Inspect the internal components of the drive (if safe and accessible) for any obvious damage or loose connections, particularly to temperature sensors.

4. 4

   Verify that the cooling fan(s) inside the drive are operating correctly and that airflow is not obstructed.

5. 5

   If the fault persists after verifying environmental conditions and cooling, the internal temperature sensor or its reading circuit is faulty, requiring service.
