Dynamics limit

The dynamics limit is dependent on the type of activation of the coupled axis grouping:
● Activation in part program
If activation is performed in the part program and all leading axes are active as program
axes in the activating channel, the dynamic response of all coupled-motion axes is taken
into account during traversing of the leading axes to avoid overloading the coupled-motion
axes.
If activation in part program takes place with leading axes that are not active as program
axes in the activating channel ($AA_TYP ≠ 1), then the dynamics of the coupled motion
axes is not considered while traversing the leading axes. This can result in an overload for
coupled motion axes with a dynamic response which is less than that required for the
coupling.
● Activation in synchronized action
If activation is performed in a synchronous action, dynamics of the coupled motion axes is
not taken into account during traversing of the leading axis. This can result in an overload
for coupled motion axes with a dynamic response which is less than that required for the
coupling.

CAUTION
Axis overload
If a coupled motion grouping
● in synchronized actions
● is activated in the part program with leading axes, that are not program axes in the
channel of the coupled motion axes,
it is the special responsibility of the user/machine manufacturer to provide suitable
measures to ensure that an overload of the coupled motion axes does not occur through
traversing of the leading axis.
