$AC_OPERATING_TIME
Total execution time in seconds of NC programs in "AUTO" mode
In "AUTO" mode, the runtimes of all programs between program start and end are summed up. The timer is zeroed after
each power-up of the control system.
●
$AC_CYCLE_TIME
Runtime of the selected NC program (in seconds)
The runtime between program start and end is measured in the selected NC program. The timer is reset with the start of
a new NC program.
●
$AC_CUTTING_TIME
Tool action time (in seconds)
The runtime of the path axes is measured in all NC programs between program start and end 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 after each power-up of the control system.
Programming example
N10 IF $AC_CUTTING_TIME>=R10 GOTOF WZZEIT
; Tool operation time limit value?
G0 X20 Y20
N80 WZZEIT:G0 X30 Y30
N90 MSG("Tool action time: Limit value reached")
