8.10 Special Cycles
DWELL TIME (Cycle G04)
This causes the execution of the next block within a running program
to be delayed by the programmed dwell time. A dwell time can be
used for such purposes as chip breaking.
Effect
Cycle 9 becomes effective as soon as it is defined in the program.
Modal conditions such as spindle rotation are not affected.
U U U U Dwell time in seconds: Enter the dwell time in
seconds.
Input range 0 to 3600 s (1 hour) in 0.001 s steps
PROGRAM CALL (Cycle G39)
Routines that you have programmed (such as special drilling cycles or
geometrical modules) can be written as main programs and then
called like fixed cycles.
U U U U Program name: Enter the name of the program you
want to call and, if necessary, the directory it is
located in.
Call the program with
n G79 (separate block) or
n M99 (blockwise) or
n M89 (executed after every positioning block)

Before programming, note the following:
If you want to define an ISO program to be a cycle, enter
the file type .I behind the program name.
Not TNC 410
If the program you are defining to be a cycle is located in
the same directory as the program you are calling it from,
you need only to enter the program name.
If the program you are defining to be a cycle is not located
in the same directory as the program you are calling it
from, you must enter the complete path (for example
TNC:\KLAR35\FK1\50.I.
