21. AXIS CONTROL FUNCTIONS
467
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 bit 2 (AZK) of parameter No. 8200 has been set to 0, such
that manual reference position return along the angular axis
also causes movement along the perpendicular axis, once
manual reference position return has been performed along
the angular axis, also perform manual reference position
return along the perpendicular axis.
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 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 ±90° 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.
