Programming principles
1.12 Timers and workpiece counters
● $AC_OPERATING_TIME
● $AC_CYCLE_TIME
● $AC_CUTTING_TIME
Programming example
N10 IF $AC_CUTTING_TIME>=R10 GOTOF WZZEIT
G0 X50 Z50
N80 WZZEIT:G0 X60 Z60
N90 MSG("Tool action time: Limit value reached")
N100 M0
M30
Display
The contents of the active system variables are visible on the screen under <OFFSET> ->
"Sett. data">"Time counter":
Total run time = $AC_OPERATING_TIME
Program run time = $AC_CYCLE_TIME
Feedrate run time = $AC_CUTTING_TIME
Time since cold restart = $AN_SETUP_TIME
Time since warm restart= $AN_POWERON_TIME
"Program run time" is also visible in the AUTOMATIC mode in the "Machine" operating area
in the information line.

Total execution time in seconds of NC programs in the automatic mode
In the AUTOMATIC mode, the runtimes of all programs between NC START and end of
program / RESET are summed up. The timer is zeroed with each power-up of the control
system.
Runtime of the selected NC program (in seconds)
The runtime between NC Start and End of program / Reset is measured in the selected
NC program. The timer is reset with the start of a new NC program.
Tool action time (in seconds)
The runtime of the path axes is measured in all NC programs between NC START and
end of program / RESET without rapid traverse active and with the tool active (default
setting).
The measurement is interrupted when a dwell time is active.
The timer is automatically set to zero with each power-up of the control system.
