8 Programming: Cycles 190
8.9 Special Cycles
DWELL TIME (Cycle 9)
This cycle 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.
ú Dwell time in seconds: Enter the dwell time in
seconds
Input range: 0 to 30 000 seconds (approx. 8.3 hours) in
increments of 0.001 seconds
Resulting NC blocks
89 CYCL DEF 9.0 DWELL TIME
90 CYCL DEF 9.1 DWELL 1.5
PROGRAM CALL (Cycle 12)
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.
ú Program name: Name of the program to be called
The program is called with
■ CYCL CALL (separate block) or
■ M99 (blockwise) or
■ M89 (modally)
Example: Program call
A callable program 50 is to be called into a program via a cycle call.
