Siemens SINAMICS V20 Operating Instructions Manual page 119

You must fit the PTC sensor to the motor and then connect it to the converter control
terminals as shown below:
To achieve EMC-compliant installation, take the following actions when connecting the PTC
sensor:
● Terminate the ends of the cable neatly, ensuring that the unshielded wires are as short as
possible.
● Separate the sensor cable from the power cables as much as possible, using separate
trunking. Cross them if necessary at 90º to each other.
● Use shielded or armored cables for the motor connections and ground the cable shields
at both ends using the cable clamps.
Cable lengths
As long as the above mentioned instructions are observed, PTC cables of several hundred
meters can be used. For longer cables, increase the conductor cross-section to avoid
measurement errors. For more information about the V20 signal cable cross-section and
user terminals, see Section "Terminal description (Page 40)".

Setting
This parameter defines reaction when motor temperature reaches warning threshold.
Settings 0 to 2 do not recall the motors temperature (stored at power-down) on pow-
er-up:
= 0: Warning only
= 1: Warning with Imax control (motor current reduced) and trip (F11)
= 2: Warning and trip (F11)
Settings 4 to 6 recall the motors temperature (stored at power-down) on power-up:
= 4: Warning only
= 5: Warning with Imax control (motor current reduced) and trip (F11)
= 6: Warning and trip (F11)
