Terminal Module 120 - Siemens Sinamics S120 Function Manual

Temperature measurement
● p0600 = 10 activates the motor temperature measurement via the external sensor.
● p0603 sets the signal source for the evaluation of the motor temperature
● p4100 = 0 disables the evaluation. Then parameter r4105 = -300°C.
PTC
● p4100 = 1 sets the PTC temperature sensor type and activates the evaluation.
● r4105 indicates the following values:
KTY84
● p4100 = 2 sets the KTY84 temperature sensor type and activates the evaluation.
● r4105 indicates the following values:
8.5.10

Terminal Module 120

If the temperature sensors in the installed motors do not have protective separation, then
you require a Terminal Module 120 (TM120). Up to 4 different temperature sensors can be
connected to the TM120. The TM120 senses the temperature actual values and evaluates
them. The fault and alarm thresholds (p4102) of the temperature actual values can be set
from -48 °C up to 251°C. Temperature sensors are connected at the TM120 at terminal strip
X521 according to the table above.
You will find additional information on this topic in the SINAMICS S120 Control Units and
Additional Components Manual.
Temperature measurement
● p0600[0...n] = 20 or 21 activates the motor temperature sensing via an external sensor.
● p0601[0...n] = 11 sets the evaluation for several temperature channels.
● p0608[0...3] allocates the temperature channels for the motor temperatures to signal

– If the temperature actual value is less than the nominal response temperature, then -
50°C is displayed.
– If the temperature actual value is higher than the nominal response temperature, then
250 °C is displayed.
– If the actual temperature value is invalid (F35920 initiated), then -300°C is displayed.
– If p4100 = 0, -300°C is displayed.
– The actual temperature value of the temperature evaluation
– -300 °C if no sensor has been selected or the temperature actual value is invalid
