Comparison: Differences in Test Run, functionality
Function TNC 640 iTNC 530
Test Run up to block N Function not available Function available
Entering a program with the GOTO
key
Function only possible if the
START SINGLE soft key was not
pressed Function also possible after START
SINGLE
Calculation of machining time Each time the simulation is
repeated by pressing the START
soft key, the machining time is
totaled Each time the simulation is
repeated by pressing the START
soft key, time calculation starts at 0
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

Function TNC 640 iTNC 530
Jog increment function The jog increment can be defined
separately for linear and rotary
axes The jog increment applies for both
linear and rotary axes
Preset table Basic transformation (translation
and rotation) of machine table
system to workpiece system via
the columns
X, Y and Z, as well as
spatial angles
SPA, SPB and SPC.
In addition, the columns
X_OFFS
to
W_OFFS can be used to define
the axis offset of each individual
axis. The function of the axis
offsets can be configured.
Basic transformation (translation)
of machine table system to
workpiece system via the columns
X, Y and Z, as well as a ROT basic
rotation in the working plane
(rotation).
In addition, the columns
A to W
can be used to define datums in
the rotary and parallel axes.
