Max. connectable cross-section 1.5 mm
Type: Screw terminal 1 (see Connection systems)
NOTICE
The KTY temperature sensor must be connected with the correct polarity.
Note
The temperature sensor connection is required for motors for which the temperature value is
not transferred using DRIVE-CLiQ.
If the "Safe standstill" 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.
