Payloads
Load center of
gravity
For all payloads, the load center of gravity refers to the distance from the face
of the mounting flange on axis 6. Refer to the payload diagram for the nominal
distance.

This loading curve corresponds to the maximum load ca-
pacity. Both values (payload and mass moment of iner-
tia) must be checked in all cases. Exceeding this capacity will reduce the
service life of the robot and overload the motors and the gears; in any such
case the KUKA Roboter GmbH must be consulted beforehand.
The values determined here are necessary for planning the robot application.
For commissioning the robot, additional input data are required in accor-
dance with the operating and programming instructions of the KUKA System
Software.
The mass inertia must be verified using KUKA.Load. It is imperative for the
load data to be entered in the robot controller!
