Measured/Estimated motor temperature 1 has exceeded the warning level. See also 4981. Wait until the motor/motor model is cooled down. The fan contactor stays on as long as the warning is pending.
Check:

The value of 35.02 Measured temperature 1.

The real motor temperature. Let motor cool down and restart.

The value of 35.13 Temperature 1 warning level.

The cooling of the motor or other temperature measured equipment.

The ambient conditions (e.g. ambient temperature).

The airflow and fan operation.

The motor fan supply voltage.

The motor fan direction of rotation.

The motor fan components.

The motor cooling air inlet (e.g. filters).

The motor cooling air outlet.

The motor load and drive ratings.

Inadmissible load cycle.

The wiring of the temperature sensor.

The resistance of the temperature sensor by measuring it.

Hint:

The measured/estimated motor temperature is blocked, if 35.11 Temperature 1 source = Disable.
