Load identification for IRBP R
A simplified view of the positioner IRBP R is shown in the following figure.
xx1000000149
Parameters
The parameters identified are the center of gravity in a plane perpendicular to the
axis, and three moments of inertia at the center of gravity. Note that both the mass
of the load and the distance z to the center of gravity must be known in advance.
These data are entered when performing the load identification.
Movements
One part of the identification movements for one axis is the same as for the
positioner IRBP L. To find the extra moment of inertia we also move the interchange
axis with the load to two different positions. The movements for the interchange
axis are the movements described in the figure in section
, but only at one configuration point.
CAUTION
The identification on one axis will be correct only if there is no load mounted on
the other axis.
