Max. connectable cross-section 1.5 mm
Type: Screw terminal 1 (see Connection Engineering section)
Notice
The KTY temperature sensor/the PTC 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 VDC and the -X21:4 terminal. For cancelation, a pulse suppression will be
activated.
