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 four different temperature sensors can
be connected to the TM120. The TM120 senses the actual temperature values and
evaluates them. The fault and alarm thresholds (p4102) of the actual temperature 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.
Note
Fault messages
Fault messages for an individual temperature channel in the TM120 are propagated to all
other drive objects connected with the TM120.
As such all other drive objects (connected with the TM120) also trigger a fault.
You will find additional information in the SINAMICS S120 Control Units and Supplementary
System 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
source 2.
● p0609[0...3] allocates the temperature channels for the motor temperatures to signal
source 3.
● p4100[0...n] = 0 deactivates temperature evaluation.
● r4101[0...3] indicates the actual resistance value of the respective temperature sensor.
The maximum measurable resistance is 2170 Ω.
● p4102[0/2/4/6] sets the alarm thresholds of the temperature sensors to between -48° C
and 250° C.
● p4102[1/3/5/7] sets the fault thresholds of the temperature sensors to between -48° C and
250° C.
● p4102[0...7] = 251° C deactivates the alarm and/or fault message that has been set.
● p4610[0...n] to p4613[0...n], assigns up to four temperature sensors to the motor and
defines the responses.
