10.1.3 Interaction Control
In nozzle attitude control, as shown in the diagram of the axis
configuration of the nozzle head, the β axis motor is arranged around
the Z axis. In the case of a structure which transmits by gear, if the α
axis is commanded, the housing rotates and the nozzle rotates around
the Z axis.
However, simultaneously at this time gear B must rotate around gear
A. This movement results in the nozzle being rotated by the β axis.
Namely, if the α axis rotates by an α axis command, a rotational
operation simultaneously occurs at the β axis.
Interaction control is the function to automatically generate
commands in the β axis of the same amount as the α axis commands
in order to cancel the rotational operation of the β axis for a nozzle
head of axis configuration such that the β axis rotates by the α axis
commands. The command polarity can be selected by parameter.

10.1.4 A-axis Length Compensation Function
When an offset nozzle is used, replacement of the machining head
may change the length of the second arm of the nozzle.
If this occurs, nozzle tip fixing control cannot be executed correctly
until the nozzle tip is returned to the reference position. By inputting,
from the program, the length of the nozzle installed at machining head
replacement, this function enables tip fixing control to be executed
with the attitude of the machine left as is.
