Monitoring and protective functions
8.5 Thermal motor protection
Function of the bimetallic NC contact
A bimetallic switch 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 the bimetallic NC contact temperature sensor type
Temperature sensor type for multiple temperature channels
If you use several temperature channels, set p0601 = 10. Then the sensors are
interconnected via BICO
8.5.3

Sensor Modules

Sensor Modules are needed when additional temperature sensors are to be connected via
DRIVE-CLiQ. Various Sensor Modules are available to do this:
● Sensor Module Cabinet-Mounted (SMC) for rail mounting in control cabinets
● Sensor Module External (SME) in degree of protection IP67, installed close to the motor
PTC and KTY84 temperature sensors - and in some cases - bimetallic NC contacts, can be
connected to the Sensor Modules.
