Set the machine coordinate value when the workpiece holder is positioned
at the tool center (punching position) by the parameters.
The detector on the machine automatically detects the positions of the
workpiece holders mounted on the carriage. Values representing the
detected positions are then set in the safety zone parameters.

The signal for detecting the position of the workpiece holders turns on and
off as workpiece holders #1 to #4 pass the detector as shown in Fig. 29.5.3.
The safety zone is determined from the signal. The position on the X axis
when the signal goes high is regarded as one end of a workpiece holder,
and the position when the signal goes low is regarded as the other end.
