Cooling method

The stator in the built-in torque motors is equipped with a liquid cooler for dissipating heat
loss.
The cooling method used depends on the size (external diameter) of the motor as follows.

Temperature monitoring and thermal motor protection

4.1.2.1

Temperature monitoring circuits Temp-S and Temp-F

The motors are equipped with the two temperature monitoring circuits – Temp-S and Temp-F
– that are described below.
● Temp-S activates the thermal motor protection when the motor windings are thermally
overloaded. In this case the precondition is that Temp-S is correctly connected and
evaluated. For a thermal overload, the drive system must bring the motor into a no-
current condition.
● Temp-F is used for temperature monitoring and diagnostics during commissioning and in
operation.
Both temperature monitoring circuits are independent of one another.
For example, the SME12x Sensor Module or the TM120 Terminal Module evaluates the
temperature sensor signals.
You can obtain commissioning information from Technical Support. Contact data is provided
in the introduction.
