8. SAFETY ZONE CHECK
1 Use bit 2 (ZI0) of parameter No. 16502 to switch between
the detection methods.
2 The position of a workpiece holder on the Y–axis cannot be
3 To enable the execution of safety zone position detection,
set a detection start position such that the distance between
the detection start position and the first end of the workpiece
holder is sufficient for the feedrate to stabilize.
4 If reset is performed during safety zone position detection,
repeat the operation from reference position return along
5 The purpose of automatic detection is to automatically
calculate the central position of a workpiece holder from the
signal transitions. Accordingly, set workpiece holder width
data in parameter Nos. 16540 to 16543 so that safety zones
can be set correctly.
6 If the number of safety zones to be set does not match the
detector signal transition count, during automatic safety
zone setting, alarm 4871 is issued.
7 When the detector signal makes a transition when position
deviation along the X–axis during movement for automatic
safety zone setting exceeds the allowable range of values
set in the parameters (Nos. 16538 and 16539), alarm 4870
