Displaying the same characters in the same positions on the screen causes
a LCD to degrade relatively quickly. To help prevent this, the screen can
be cleared by pressing specific keys. It is also possible to specify the
automatic clearing of the screen if no keys are pressed during a period
specified by a parameter.
However, it is disabled for the open CNC.
Holding down the
CAN
key and pressing a function key clears the screen.
Hold down the
CAN
key and press a function key (such as
POS
and
PROG
).
Press a function key, to restore the display.
The CNC screen is automatically cleared if no keys are pressed during the
period (in minutes) specified by parameter (No. 3123). The screen is
restored by pressing any key.
The CNC screen is cleared once the period (minutes) specified with
parameter No. 3123 has elapsed, provided the following conditions are
satisfied:

D Parameter No. 3123 is non–zero.
D None of the following keys have been pressed:
MDI keys
