Max. connectable cross-section 1.5 mm
Type: Screw terminal 1 (see Connection System)
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.
