1.12 Timers and workpiece counters
1.12.1 Runtime timer
Functionality
The timers are prepared as system variables ($A...) that can be used for monitoring the
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
● $AN_SETUP_TIME
Time since the last control powerup with default values (in minutes)
It is automatically reset in the case of a "Control power-up with default values".
● $AN_POWERON_TIME
Time since the last control powerup (in minutes)
It is reset to zero automatically with each power-up of the control system.
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.
