foundation. The quality of the concrete must meet the requirements of the fol-
lowing standard:

C20/25 according to DIN EN 206-1:2001/DIN 1045-2:2008
6.3 Connecting cables and interfaces
Description
The connecting cables comprise all the cables for transferring energy and sig-
nals between the robot controller and the robot. They are connected by means
of connectors to the robot controller and to the connector plate on the energy
supply chain of the axis module. The cables between the connector plate and
the robot (junction boxes) are part of the energy supply chain. Depending on
the specific application, the energy supply chain may also contain further ca-
bles and hoses.
The set of connecting cables comprises:

Motor cable, X20 - X30

Data cable X21 - X31

Ground conductor (optional)
Depending on the specification of the robot, various connecting cables are
used. Cable lengths of 7 m, 15 m, 25 m and 35 m are available. The maximum
length of the connecting cables between the robot controller and the junction
boxes must not exceed 50 m. The cable lengths in the cable carrier must be
taken into consideration.
For the connecting cables, an additional ground conductor is always required
to provide a low-resistance connection between the robot and the control cab-
inet in accordance with DIN EN 60204. The ground conductors are connected
via ring cable lugs. The threaded bolts for connecting the ground conductor
are located on the controller and on the connector plate of the cable carrier of
the energy supply system of the robot (axis module).
Detailed information about the wiring diagrams, connector pin allocations and
connector designations can be found in section .
The following points must be observed when planning and routing the con-
necting cables:

The bending radius for fixed routing must not be less than 150 mm for mo-
tor cables and 60 mm for control cables.

Protect cables against exposure to mechanical stress.

Route the cables without mechanical stress – no tensile forces on the con-
nectors

Cables are only to be installed indoors.

Observe permissible temperature range (fixed installation) of 263 K (-
10 °C) to 343 K (+70 °C).

Route the motor cables and the data cables separately in metal ducts; if
necessary, additional measures must be taken to ensure electromagnetic
compatibility (EMC).
Interface for
energy supply
system
The KR 30, 60 JET ROBOT can be equipped with an energy supply system
for axis 1 to axis 3. The necessary interface – interface A3 on the arm – is sit-
uated on the left-hand side of the robot. The interface is equipped with con-
nections for cables and hoses depending on the application. Detailed
information on the connector pin allocation, threaded unions, etc. is given in
separate documentation.
