Link arm
The link arm is the assembly located between the arm and the rotating
column. There are two length variants of the link arm available. There is
an interface on the link arm for fastening supplementary loads.
Rotating column
The rotating column houses the gear units and motors A1 and A2. The ro-
tational motion of axis 1 is performed by the rotating column. This is
screwed to the base frame via the gear unit of axis 1 and is driven by a
motor in the rotating column. The link arm is also mounted in the rotating
column.
There is an interface on the rotating column for fastening supplementary
loads.
Base frame
The base frame is the base of the robot. It is screwed to the mounting
base. The electrical installations are fastened in the base frame. Also lo-
cated on the base frame is the interface for the motor and data cable and
the energy supply system.
Electrical installations
The electrical installations include all the motor and data cables for the
motors of axes 1 to 6. The complete electrical installations consist of ca-
ble set A1 - A3 and cable set A4 - A6.
All connections are implemented as connectors in order to enable the
main axis motors to be exchanged quickly and reliably. The electrical in-
stallations also include a protective circuit. The ground conductors to the
robot are connected to the base frame by means of ring cable lugs and
setscrews.
