8. SAFETY ZONE CHECK
145
[Classification] Input signal
[Function] These signals are used to select a tool area for safety zone checking. These
signals must be changed while a T code is being read or upon reset of
CNC.
[Operation] The table below indicates the correspondence between the SZTS0 to
SZTS3 signals and parameter settings.

[Classification] Output signal
[Function] Each signal notifies the PMC that the corresponding tool area is in a safety
zone. For example, a virtual area which is larger than the selected tool area
can be set using the safety zone tool area select signals (SZTS0 to SZTS3).
Thus, the command for positioning the tool near a workpiece holder is
known beforehand, allowing interference to be avoided by changing the
positioning path with the interlock function (for type B).
