Device overtemperature shutdown

What does F2018 mean?

The drive controller or associated power electronics have reached a critical internal temperature, triggering a safety shutdown to prevent damage. This is a severe thermal event.

• Inadequate cooling for the drive due to blocked vents, fan failure, or high ambient temperature.
• Sustained operation at or above the drive's rated output current.
• Internal thermal sensor malfunction or incorrect reading.
• Failure of internal cooling components.

Click steps to track your progress.

1. 1

   Allow the drive controller to cool down completely before attempting to reset the fault.

2. 2

   Check the drive's cooling fan for proper operation. Verify airflow direction and ensure no obstructions in the heatsink or ventilation openings.

3. 3

   Measure the ambient temperature around the drive and ensure it is within the specified operating range.

4. 4

   Reduce the load on the drive if possible, or verify that the drive is correctly sized for the application's continuous and peak current requirements.
