1.5.1 Introduction to Load diagrams
Information
General
The load diagrams include a nominal payload inertia, J
load of 20 kg (IRB 6660-130/3.1 and IRB 6660-100/3.3) and 15 kg (IRB 6660-205/1.9)
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 verify a specific load case, use the RobotStudio add-in RobotLoad.
The result from RobotLoad is only valid within the maximum loads and tilt angles.
There is no warning if the maximum permitted arm load 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 is used, and/or if loads outside the load diagram are used,
the following parts can be damaged due to overload:
• motors
• gearboxes
• mechanical structure
WARNING
In RobotWare, the service routine LoadIdentify can be used to determine correct
load parameters. The routine automatically defines the tool and the load.
See Operating manual - OmniCore, for detailed information.
WARNING
Robots running with incorrect load data and/or with loads outside the load
diagram, will not be covered by robot warranty.
