Further labels
Note
Further labels are enclosed in the packaging. If the motor is visible and touchable following
installation, attach the enclosed labels to further sides of the motor where applicable.
2.6.2 Bearing version
The 1FK7 motors are equipped with permanently lubricated deep-groove ball bearings. The
location bearing is at the DE.
2.6.3 Thermal motor protection
A temperature-dependent resistor is integrated as temperature sensor to monitor the motor
temperature.
• Starting in 2017, 1FK7 motors with integrated DRIVE-CLiQ interface are generally changed
to the Pt1000. The marking is made with the revision number of the motors. The order
number does not need to be changed.
• Motors without integrated DRIVE-CLiQ interface are converted with changed order
number to the new Pt1000 temperature sensor. In connection with the following
encoders without DRIVE-CLiQ, the 12th digit of the order number must be changed
accordingly.
