14.18 Interference Check III
Mode enable command
While the "Interference check III: Interference check III mode" signal (Y76A) is ON after the "Interference check III: Enable
interfering object selection data" signal (Y769) or the enable interference check III setting data command (G186) is executed,
the interference check between interfering objects is performed. While the interference check III is being executed, the
"Interference check III: In interference check III mode" signal (X772) is turned ON.
After NC power is turned ON, if the interference check III mode is turned ON without executing the "Interference check III:
Enable interfering object selection data" signal (Y769) or the enable interference check III setting data command (G186) even
once, the operation error (M03 1001) occurs.
