Timers for program execution time

Function
Timers are provided under the "Program execution time" function and these can be used for
monitoring technological processes in the program or only in the display. These timers are
read-only.
There are timers that are always active. Others can be deactivated via machine data.
Timers - always active
● Time since the last "Control powerup with default values" (in minutes):
● Time since the last control powerup (in minutes):
Timers that can be deactivated
The following timers are activated via machine data (default setting). The start is timer-
specific. Each active run-time measurement is automatically interrupted in the stopped
program state or for feedrate-override = zero.
The behavior of the activated timers for active dry run feedrate and program testing can be
specified using machine data.
● Total execution time in seconds of NC programs in the automatic mode (in seconds):
● Runtime of the selected NC program (in seconds):
● Tool action time (in seconds):
Turning, Milling, Nibbling

$AN_SETUP_TIME
The timer is automatically reset to zero in the case of a "Control power-up with default
values".
$AN_POWERON_TIME
It is reset to zero automatically with each power-up of the control system.
$AC_OPERATING_TIME
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.
$AC_CYCLE_TIME
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.
$AC_CUTTING_TIME
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. The
measurement is interrupted when a dwell time is active. The timer is automatically reset
to zero in the case of a "Control power-up with default values".
