Overview
Connection system MOTION-CONNECT 300
The MOTION-CONNECT 300 cables in this catalog are suitable
for the use with standard turning and milling machines.
The use of pre-assembled MOTION-CONNECT 300 cables en-
sures high quality and system-tested, problem-free operation.
Degree of protection of pre-assembled power and signal cables
and their extensions is IP65 when closed and connected unless
otherwise stated.
MOTION-CONNECT 300 cables are not suitable for outdoor use.
MOTION-CONNECT cables are approved for a maximum
horizontal travel distance of 5 m without support.
The cables must be unwound without twisting.
To maximize the service life of the cable carrier and cables,
cables in the carrier made from different materials must be
separated in the cable carrier using spacers. The spacers must
be filled evenly to ensure that the position of the cables does not
change during operation. The cables should be distributed as
symmetrically as possible according to their weights and dimen-
sions. Cables with different outer diameters should be separated
by spacers as well.
When inserting pre-assembled cables into the cable carrier, do
not pull at the connector, as this may damage the strain relief or
cable clamping.
The cables must not be fixed in the cable carrier. They must be
freely movable.
The cables must be able to be moved without applying force,
specifically in the bending radii of the carrier. The specified
minimum bending radii must be adhered to.
The cable fixings must be attached at both ends at an appropri-
ate distance from the end points of the moving parts in a dead
zone.
Cables must be installed in accordance with the instructions
supplied by the cable carrier manufacturer.
In case of vibration load and with horizontal or vertical cable
entries, we recommend that the cable is additionally fixed if
between the cable strain relief on the cable carrier and the
terminal at the motor part of the cable is hanging loose or is not
routed. To prevent machine vibrations being transmitted to the
connectors, the cable should be fixed at the moving part where
the motor is mounted.
