Activating the machining time display
Timers are provided as system variables in the Program runtime function. While the NCK-
specific timers are always activated (for time measurements since the last controller power-
up), the channel-specific timers must be started via the following channel-specific machine
data.

tailstock diameter.
The tailstock dimensions are written into the following machine data:
Tailstock enable:
The tailstock becomes visible if selected in the "tailstock" program.
The measurement of the total runtime for all part programs is active
($AC_OPERATING_TIME).
The measurement of the actual program runtime is active ($AC_CYCLE_TIME).
Measurement also during active dry run feedrate.
Measurement during program test.
