Mechanical properties
3.2 Degree of protection
1FK2 synchronous motors for SINAMICS S120
30 Configuration Manual, 06/2019, A5E46927724B AB
The converter monitors the motor temperature based on a thermal motor model and issues
the alarm "Motor overtemperature" before the maximum temperature is reached. When the
motor exceeds the maximum temperature, the converter switches off the motor with the error
message "Motor overtemperature".
When the ambient temperature exceeds 40 °C, set the ambient temperature on the
converter.
● To do this, select parameter p0613 at the converter.
Parameter r0034 indicates the thermal load of the motor as a percentage. The reading of
parameter r0034 depends on the ambient temperature defined via parameter p0613.
For more details about parameter p0613, see "SINAMICS S120 List Manual".
1FK2 motors can be delivered with degree of protection IP64 or IP65.
The degree of protection is stated on the rating plate.
The motors with degree of protection IP65 have a radial shaft sealing.
Radial shaft sealing ring
The radial shaft sealing ring shortens the usable shaft extension on the 1FK2❑03 and
1FK2❑04.
Note
It is permissible that the radial shaft sealing ring runs dry.
With degree of protection IP65, it is not permissible for liquid to collect in the flange.
fe of the radial shaft sealing ring is approximately 25000 operating hours.
For additional information, see Chapter "Shaft extension (Page 31)".
