H11 (Temperature sensor error: Temperature inside the controller)
Lenze · 9300 Series
Hva betyr 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.
Vanlige årsaker
- 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.
Reparasjonssteg & Sjekkliste
Klikk på steg for å spore fremgangen.
- 1
Perform a power cycle to the drive by disconnecting mains power for at least 30 seconds.
- 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
Inspect the internal components of the drive (if safe and accessible) for any obvious damage or loose connections, particularly to temperature sensors.
- 4
Verify that the cooling fan(s) inside the drive are operating correctly and that airflow is not obstructed.
- 5
If the fault persists after verifying environmental conditions and cooling, the internal temperature sensor or its reading circuit is faulty, requiring service.
