Calling a cycle in connection with point tables

With CYCL CALL PAT the TNC runs the point table
that you last defined (even if you defined the point
table in a program that was nested with CALL PGM).
If you want the TNC to call the last defined fixed cycle at the points
defined in a point table, then program the cycle call with CYCLE
CALL PAT:
Program the cycle call: Press the CYCL CALL key
Call the point table: Press the CYCL CALL PAT soft
key
Enter the feed rate at which the TNC is to move
from point to point (if you make no entry the TNC
will move at the last programmed feed rate; FMAX
is not valid)
If required, enter a miscellaneous function M, then
confirm with the END key
The TNC retracts the tool to the safety clearance between the
starting points. Depending on which is greater, the TNC uses either
the spindle axis coordinate from the cycle call or the value from
cycle parameter Q204 as the clearance height.
If you want to move at reduced feed rate when pre-positioning in
the spindle axis, use the miscellaneous function M103.
Effect of the point tables with SL cycles and Cycle 12
The TNC interprets the points as an additional datum shift.
Effect of the point tables with Cycles 200 to 208 and 262 to 267
The TNC interprets the points of the working plane as coordinates
of the hole centers. If you want to use the coordinate defined in
the point table for the spindle axis as the starting point coordinate,
you must define the workpiece surface coordinate (Q203) as 0.
