9. SAFETY ZONE AREA EXTENSION
B–63683EN/01
158
(a) Tool selection signals and in safety zone signals
For an extended tool selection, tool selection signals SZTS0 to
SZTS3 (G0232, #0 to #3) are used. The in safety zone signals are
output to SZT13 to SZT16 (F0238, #4 to #7). For details, see
Section 9.4, ”ADDITIONAL SIGNALS.”
(b)Safety zone setting screen
The data of 16 selectable tool areas can be displayed and specified.
(3)Interference safety zone area signals
(a) Safety zone interference area signal (F228)
This signal notifies the PMC of the safety zone in which a selected
tool (including shear tool areas 1 to 3) enters. For details, see
Section 9.4, ”ADDITIONAL SIGNALS.”
(4)Improving the automatic safety–zone setting
The conventional automatic safety–zone setting function
automatically sets a safety zone according to the travel direction at the
position detection of the workpiece holder. If eight areas are used with
the safety zone area extension function, the safety zones are always
automatically and successively specified with the mechanical position
relationship of #n < #(n + 1), starting from #1, irrespective of the travel
direction at the position detection of the workpiece holder.
This function is enabled if the EXSF8 bit (bit 4 of parameter 16503)
is set to 1.
