am Run
 Go to the first block of the current program to start a block scan:
Enter GOTO "0"
 Select mid-program startup: Press the MID-
PROGRAM STARTUP soft key
 Block number : Enter the block number at which the
block scan should end
 Program name
: Enter the name of the program in which
you want to start. A change is only required if you
want to start with a program that was called with
PGM CALL.
 Point index : If you have entered a block number
containing a CYCL CALL PAT block in the Start-up at
N
field, the TNC displays the point pattern graphically
in the File preview field. Using the NEXT ELEMENT
or PREVIOUS ELEMENT soft key you can select the
start position with graphic support if the preview
window is currently displayed (set PREVIEW soft key
to ON)
 Repetitions
: If block N is located in a program section
repeat or in a subprogram that is to be run repeatedly,
enter the number of repetitions to be calculated in the
block scan
 Start mid-program startup: Press the machine START
button
 Contour approach (see following section)
Entering a program with the GOTO key
Danger of collision!
If you use the GOTO block number key for going into a
program, neither the TNC nor the PLC will execute any
functions that ensure a safe start.
If you use the GOTO block number key for going into a
subprogram, the TNC will skip the end of the subprogram
(LBL 0)! In such cases you must always use the mid-
program startup function.
