Cause : MOTOR 2 TEMP comes when measured motor temperature has exceeded alarm limit set by parameter 35.05. This signifies that the measured temperature of the motor has exceeded a pre-set alarm limit but is likely not high enough to trigger a complete drive shut down.

The code 4313 in your ABB ACS800 drive indicates a motor temperature alarm. This signifies that the measured temperature of the motor has exceeded a set alarm limit. It's important to address this warning to prevent potential motor damage.

1. Check value of alarm limit.
2. Check that actual number of sensors corresponds to value set by parameter.
3. Let motor cool down.
4. Ensure proper motor cooling: Check cooling fan, clean cooling surfaces, etc.
