Comparison: Differences in Program Run, operation
Function TNC 640 iTNC 530
Arrangement of soft-key rows and
soft keys within the rows
Arrangement of soft-key rows and soft-keys varies depending on the
active screen layout.
Operating-mode switchover after
program run was interrupted by
switching to the Single Block
mode of operation, and canceled
by
INTERNAL STOP
When you return to the Program
Run mode of operation: Error
message
Selected block not
addressed. Use mid-program
startup to select the point of
interruption
Switching the operating mode
is allowed, modal information
is saved, program run can be
continued by pressing NC start
GOTO is used to go to FK
sequences after program run was
interrupted there before switching
the operating mode
Error message FK programming:
Undefined starting position
GOTO allowed
Entering with GOTO in the
Program run single block
Function is only possible if the NC
program was not yet started or
after pressing the
INTERNAL STOP
soft key INTERNAL STOP
Function also possible after
starting the NC program
Mid-program startup:
Behavior after restoring the
machine status
The menu for returning must
be selected with the
RESTORE
POSITION soft key
Menu for returning is selected
automatically
Completing positioning for mid-
program startup
After position has been
reached, positioning mode
must be exited with the
RESTORE POSITION soft key
The positioning mode is
automatically exited after the
position has been reached
Switching the screen layout for
mid-program startup
Only possible, if startup
position has already been
approached
Possible in all operating states
Error messages Error messages are still active
after the error has been corrected
and must be acknowledged
separately
Error messages are sometimes
acknowledged automatically after
the error has been corrected
Point patterns in single block With point pattern cycles and
CYCL CALL PAT, the control stops
after each point.
Point pattern cycles and CYCL
CALL PAT are handled by the
control as a single block
