Cause : Measured temperature 1 or 2 has exceeded warning limit.
1. Check the values of parameters
35.02 - Measured temperature 1 and
35.03 - Measured temperature 2.
2. Check the cooling of the motor (or other equipment whose temperature is being measured).
3. Check the warning limits for measured temperatures 1 and 2 in parameter group 35 Motor thermal protection.
