6.3.5 Control operational
If the control is operational, i.e. a positioning or M-function is performed, the status window displays
the symbol "*". If a current NC-program is interrupted with the external stop key, the "*" will flash in
the status-display.

M2183 Program interruption (display "Control
operational" flashes) NC NC
M2184 Control operational (display "Control
operational" on or flashes) NC NC
6.3.6 Cancel status display
A machine parameter can be used to define whether the status display should be reset with the M-
functions M02 and M30, as well as with NC-block "END PGM" . All the programmed values in the
status display, e.g. tool number, tool length, tool radius, scaling factor, datum-shift, feed rate etc.,
will then be reset.
The Q-parameters Q0–Q255 are not immediately deleted after a power interruption. They are stored
in the battery-buffered memory. They are not defined as deleted until a program is selected with the
keys "PGM NR" and "ENT."

6.4 Display of currently active power stage number
In the operating modes "Program run/single block" and "Program run/full sequence", the currently
active power stage and the first erosion parameters (LV, HV, GV, TON, TOF, SV, AJD and ET) are
displayed above the status window and can be changed directly (temporarily) with the cursor keys if
the erosion tables are activated with machine parameter MP2199 (see chapter "Eroding parameters")
6.5 Display of actual machining time
Between the erosion table with the actual power stage and the status window the actual machining
time can be displayed using MP7272 (only TNC 306).
