Auxiliary fan not running

What does 5081 mean?

An auxiliary fan fault has been detected; the auxiliary fan is not running. This compromises secondary cooling. The drive trips after a 2-minute suppression period during power-up, during which it only issues a warning. Continued operation without auxiliary cooling can lead to overheating.
