TM120
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 values, evaluates them, and
sends them via DRIVE-CLiQ to the Control Unit. The actual temperature values measured
using KTY84 or PT1000 are evaluated in the range from -140° C to +188.6° C. Actual
temperature values outside this range are not taken into account. The fault and alarm
thresholds (p4102) of the temperature values can be set from -48° C to 251° C.
Settings for the measurement:
● With p0600 = 20 or 21, the motor temperature sensing is activated using an external
sensor.
● With p0601 = 11, the evaluation is set over several temperature channels.
● In p0604, the motor temperature alarm threshold is set.
● In p0605, the motor temperature fault threshold is set.
● With p0608 and p0609, the temperature channels are assigned to the signal sources for
the motor temperatures.
– With p4100[0...3] = 1, temperature sensor type PTC is set to the corresponding
– With p4100[0...3] = 2, temperature sensor type KTY84 is set to the corresponding
– With p4100[0...3] = 4, the temperature sensor type bimetal NC contact is set and the
– With p4100[0...3] = 6, temperature sensor type PT1000 is set to the corresponding
● The actual resistance value of the particular temperature sensor is displayed in parameter
r4101[0...3].
● For p4102[0...7] = 251° C, the evaluation of the associated threshold is deactivated.
For sensor type "PTC thermistor" (p4100[0...3] = 1), the following applies:
To activate the associated alarm or fault, p4102[0...7] ≤ 250° C must be set.
● The actual temperature value of the temperature evaluation is displayed in parameter
r4105[0...3]. If no sensor has been selected, or if the actual temperature value is invalid,
then the value -300° C is in parameter r4105[0...3].
● With p4610[0...n] to p4613[0...n], the temperature sensors are assigned to the motor and
the response defined.
TM150
The Terminal Module 150 (TM150) has 6x 4-pole terminals for temperature sensors.
Temperature sensors can be connected in a 2, 3 or 4-wire system. Up to 12 input channels
can be evaluated if two 2-wire sensors are connected to the 4 poles at the input terminal
strips. Twelve (12) input channels can be evaluated in the factory setting. The temperature
channels of a TM150 can be subdivided into 3 groups and evaluated together.
