− Insert new block before following block
− Save axis positions in following block or insertion block
− Generate insertion block with axis positions (see description and
examples for edit mode)
You can interrupt program execution even within a subroutine.
However TEACH IN is only possible in the main program level.
The axis positions can be approached using the travel keys or the handwheel if
JOG/handwheel has been enabled.
If the modifications have been made in the block following the breakpoint, this
position is approached after NC start. You can single-step or travel to the next
breakpoint.
You can only switch between "Edit mode" and "Teach-in block by block" after
pressing RESET.
•
An existing program has been selected in the TEACH IN basic display
using SELECT PROGRAM.
• A program breakpoint has been selected (see the section "Setting
breakpoints").
Press the TEACH BLOCK BY BLOCK softkey. The following softkey bar is
displayed:
Enable JOG/ Mark
handwheel target block
Press this softkey to enter the block structure settings.
The "Block structure/settings" and "Axis selection" selection screens are
displayed (see the section "Edit mode"). Since it is possible to interrupt the
execution of a program in teach block by block and to edit the program at the
breakpoint, the entire "environment" of the program is active. This means that
in contrast to edit mode, you don't need to set the zero offset and workpiece
dimensions in the block structure. The actual values are used in the block by
block teach-in.
The block number and block number difference settings are also valid in the
NCK editor.
