The rotary axes are not orientation axes, as used for the 5-axis-transformation.
Defining rotation axes (more than two rotary axes)
If a tool carrier comprises more than two rotation axes, this is defined via the relevant axes
using the system variable $TC_CARR_KIN_ROTAX_NAME. The name of the chain element is
entered in the system variable in this regard. The maximum two rotary axes are defined in the
sequence in which they are defined in the kinematic chain. The entries must begin with the
index "0".
Syntax
