NC programs with "swivel additive" must be run-in again if the angular range of the rotary axes of the
swivel data set >=720 degrees.
Angular range, rotary axis 1 $TC_CARR30[n] $TC_CARR32[n]
Angular range, rotary axis 2 $TC_CARR31[n] $TC_CARR33[n]
with n..number of the swivel data set
(2) Note regarding the behavior when swiveling in the pole position
The behavior when swiveling in the initial state (pole position) has changed (if _ZSD[14] =1 -> refer
further below). With this debug, the input values when rotating around the tool axis, can also be
reproduced (tracked) at the machine. This can only occur if the rotary axis involved also has the
traversing range in the TCARR data.
Example:
Machine with mixed kinematics
Rotary axis 1 -> B around Y
Rotary axis 2 -> C around Z
Programming:
CYCLE800(...., rotation around Z 300 degrees,...)
If, in rotary axis C, a traversing range of 0 ..360 degrees has been entered, axis C must move to 300
degrees. This is also true if, in rotary axis C, -360 to +360 degrees has been entered.
If, for instance, the traversing range of the C axis is 0 to +180, the value of 300 cannot be approached
and therefore the expectations of the programmer cannot be fulfilled. In this case, 120 degrees would be
approached.
Setting via _ZSD[14]
