B–63534EN/02
538
An absolute and a relative position are indicated in the programmed
Cartesian coordinate system.
A machine position indication is provided in the machine coordinate
system where an actual movement is taking place according to an
inclination angle. However, when inch/metric conversion is performed,
a position is indicated which incorporates inch/metric conversion applied
to the results of inclination angle operation.
WARNING
1 After angular axis control parameter setting, be sure to
perform manual reference position return operation.
2 If once manual reference position return has been
performed along the angular axis, also perform manual
reference position return along the perpendicular axis.
P/S alarm No.090 is issued when an attempt is made to
manually return to the reference position along the
perpendicular axis although the angular axis is not on the
reference point.
3 Once the tool has been moved along the angular axis when
perpendicular/angular axis control disable signal NOZAGC
has been set to 1, manual reference position return must be
performed.
4 Before attempting to manually move the tool along the
angular and perpendicular axes simultaneously, set
perpendicular/angular axis control disable signal NOZAGC
to 1.
NOTE
1 For arbitrary angular axis control B, if the same axis number
has been specified in both parameters No.8211 and 8212,
or if a value outside the valid data range has been specified
for either parameter, the angular and perpendicular axes
become the following:
Angular axis: Second axis
Perpendicular axis: Third axis
2 If an inclination angle close to 0° or ±90° is set, an error can
occur. (A range from ±20° to ±60° should be used.)
3 Before a perpendicular axis reference position return check
(G27) can be made, angular axis reference position return
operation must be completed.
