Temperature The resistance change is proportional to the winding temperature
sensor change.
Temp–F
Resistance when cold (20 °C): approx. 580 Ohm
Resistance when hot (100 °C): approx. 1000 Ohm

Note
The temperature sensor (Temp–F) only evaluates the winding
temperature of one phase in the primary section. However, the phases
in the synchronous motor are loaded to different degrees depending on
the particular load, so that in the worst case, the phases, not
measured, have the higher temperatures.

4.10 Linear motors (1FN1, 1FN3 motors)
1FN1:
Pre–warning at 120 °C
Trip at 155 °C  5 °C
(standard setting)
1FN3:
Pre–warning at 100... 110°C (depending
on the machine type)
Trip at120 °C  5 °C
If the user carries out an additional high–voltage check, the cable
ends of the Temp–F should be short–circuited before the check! If
the test voltage is connected to the temperature sensors, it will
destroy them.
When connecting–up Temp–F, please observe the polarity!
