Siemens SIMOTICS S-1FK2 User Manual

3.5 Thermal motor protection
To protect the motor from overheating, a thermal motor type is implemented in the SINAMICS
S120 converter.
If the motor is operated within the permissible ambient temperature range and the ambient
temperature is correctly set in the converter, the converter protects the motor from overheating.
Before the motor reaches the maximum temperature, the converter outputs the warning "Motor
overtemperature".
If the motor exceeds the maximum temperature, the converter switches o󹪜 the motor with the
error message "Motor overtemperature".
If the ambient temperature exceeds 40 °C, you must adjust the ambient temperature in the
thermal motor model. In this case, the thermal protection routine requires that the ambient
temperature is speci󹪝ed in parameter p0613. For more details about parameter p0613, see
"SINAMICS S120 List Manual".
