NOTICE 
 
The KTY temperature sensor must be connected with the correct polarity. 
 
 
Note 
The temperature sensor is required for motors for which the temperature value is not 
transferred using DRIVE-CLiQ. 
If the "Safe torque Off" function is selected, for operation, ground must be placed at the  
-X21:3 24 V DC and the -X21:4 terminal. Upon removal, pulse suppression is activated.
