The temperature sensor is connected to the Sensor Module at the appropriate terminals (-
Temp) and (+Temp) (see the relevant section in the SINAMICS S120 Control Units and
Supplementary System Components Manual). A KTY84/1C130 temperature sensor has an
almost linear characteristic and is therefore also suitable for continuously measuring and
displaying the motor temperature.
You can find more detailed information on measurable actual temperature values or on
adjustable temperature values for fault and alarm thresholds in the SINAMICS S120
Commissioning Manual with STARTER, in Chapter "Temperature sensors for SINAMICS
components".
● p0600 = 1 activates the motor temperature sensing using sensor 1
● p0601 = 2 sets temperature sensor type "KTY"
Function of the PT100/PT1000
A PT100 or PT1000 is in principle a PTC with a very linear characteristic, and is suitable for
continuous and exact temperature measurements. Not every sensor input is PT100/PT1000-
capable.
You can find more detailed information on measurable actual temperature values or on
adjustable temperature values for fault and alarm thresholds in the SINAMICS S120
Commissioning Manual with STARTER, in Chapter "Temperature sensors for SINAMICS
components".
● p0600 = 1 activates the motor temperature sensing using sensor 1
● p0601 = 5 sets temperature sensor type "PT100"
or
● p0601 = 6 sets temperature sensor type "PT1000"
Function of the bimetallic NC contact
A bimetallic NC contact at a certain nominal response temperature actuates a switch. The
tripping resistance is <100 Ohm. Not every sensor input is bimetal NC contact-capable.
● p0600 = 1 activates the motor temperature sensing using sensor 1
● p0601 = 4 sets temperature sensor type "Bimetallic NC contact"
Temperature sensor type for multiple temperature channels
Set p0601 = 10 if you wish to use several temperature channels. The sensors are then
interconnected via BICO
