3.3.4 BLOCK INPUT Screen
In the upper part of general
displaying area the current posi-
tion can be seen. It is possible to
enter single block as well as to
re-execute or to modify a block
entered earlier on by pressing
action menu key . A sing-
le block is to be entered similarly
to that of a program block, how-
ever in the address chain of the
single block the address letters,
of which the entering would be
here senseless are automatically
not specified. Entering single
block is only possible in jog
(JOG), incremental jog (INCR), or manual handle feed (HNDL) mode, otherwise by pressing
action menu key the address chain does not even show up.
Actions of BLOCK INPUT Screen
After pressing action menu key the following actions are available to the BLOCK
INPUT screen:

I Action: The key makes it possible to switch the I (incremental) operator on and off on the
current address letter. When executing a letter I shows up directly after the coordinate
address.
Block Delete Action: The key serves for deleting a block in the single block buffer (that has
been written in earlier on).
Help: if the cursor stands on a G function and softkey Help is pressed, than the illustration of
the G code execution is drawn on screen.
The single block is to be terminated by key . In this case caption SBEX occurs in the 2
nd
field of status bar. By affecting START button the single block is executed. The
execution of a single block can be interrupted by means of RESET key (even before
pressing the START button), this way the previous block can be re-edited. The block in the
buffer is kept until the power is turned off.
