3. Click on the “Smoothing” button in the circuit diagram of the displayed temperature
sensor/channel (for sensor 5: p4119[5] = 1).
Figure 9-3 Smoothing time of a temperature sensor/channel.
Thus the filter to smooth the temperature signal is activated. Under the "Smoothing"
button, an entry field for the necessary smoothing time constant (p4122[0...11]) is
displayed.
4. Enter the required smoothing time constant (p4122) into the entry field.
The smoothing time constants can be calculated using the aforementioned formula. To
do this, you have to know over how many temperature channels you wish to configure a
smoothing time.
The implemented smoothing time is displayed after the entry in p4122 beneath the entry
field for the selected temperature channel (r4120[0...11]).
5. Repeat steps 2 to 4 for all temperature sensors/channels used.

Motor Module/Power Module chassis format
Motor Modules have a direct connection for a motor temperature sensor. You can evaluate
PTC, KTY84, PT100, PT1000 temperature sensors or bimetallic NC contacts. The terminals
of the temperature sensors at a Motor Module depend on their design.
