1.4.1 Introduction to load diagrams
Information
General
The load diagram includes a nominal pay load inertia, J
extra load of 0.3 kg at the upper arm housing. At different moment of inertia the
load diagram will be changed. For robots that are allowed tilted, wall or inverted
mounted, the load diagrams as given are valid and thus it is also possible to use
RobotLoad within those tilt and axis limits.
Control of load case with RobotLoad
To easily control a specific load case, use the calculation program ABB RobotLoad.
Contact your local ABB organization for more information.
The result from RobotLoad is only valid within the maximum loads and tilt angles.
There is no warning if the maximum permitted armload is exceeded. For over load
cases and special applications, contact ABB for further analysis.

WARNING
It is very important to always define correct actual load data and correct payload
of the robot. Incorrect definitions of load data can result in overloading of the
robot.
If incorrect load data and/or loads are outside load diagram is used the following
parts can be damaged due to overload:
• motors
• gearboxes
• mechanical structure
WARNING
In the robot system there is a service routine called LoadIdentify available, which
allows the user to make an automatic definition of the tool and load, to determine
correct load parameters. See Operating manual - IRC5 with FlexPendant.
WARNING
Robots running with incorrect load data and/or with loads outside diagram, will
not be covered by robot warranty.
