Displaying the same characters in the same positions on the screen causes
a CRT 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 with a parameter.
Holding down the
CAN
key and pressing an arbitrary function key clears
the screen.
Hold down the
CAN
key and press an arbitrary function key (such as
POS
and
PROG
).
Press an arbitrary function key, when the screen is displayed again.
The CNC screen is automatically cleared if no keys are pressed during the
period (in minutes) specified with a 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:
Conditions for clearing the CNC screen

D Parameter No. 3123 is set to other than 0.
D None of the following keys have been pressed:

D No alarm has been issued.
The cleared CNC screen is restored once at least one of the following
conditions is satisfied:
Conditions for restoring the CNC screen
