External Data Input/Output Data Table
SUPPLEMENT
1. External work number designation
• In the external work number input state, if the specified work number is not in the range
from 1 to 9999 or if the specified work number is not found, the ALMS is output.
• If the operating output signal (OP) is “closed”, external work number search is not
allowed.
2. External tool offset
• The offset data are corrected for the offset number which is specified by the program.
• Offset data correction is executed either by adding the external input value to the existing
offset data or by replacing the existing offset data with the external input value. Which of
the correction methods should be used is determined by the following external inputs (axis
selection bit is used).
EDAS2 = 0 Addition
