Comparison: Differences in Program Run, traverse
movements
Danger of collision!
NC programs that were created older controls can lead to
unexpected axis movements or error messages on current
control models. Danger of collision during machining!
Check the NC program or program section using the graphic
simulation
Carefully test the NC program or program section in the
Program run, single block operating mode
Pay attention to the following known differences (the list
below might not be complete!)
Function
Handwheel-superimposed travers-
ing with M118
Deleting basic rotation with M143
Scaling approach/departure
movements (APPR/DEP/RND)
Approach/departure with APPR/DEP
Approach/departure with APPR/DEP
if contour elements with length 0
are defined

Tables and Overviews | Differences between the TNC 620 and the iTNC 530
NOTICE
TNC 620
Effective in the machine coordinate
system
M143 clears the entries from the
SPA, SPB and SPC columns in the
preset table
Axis-specific scaling factor is
allowed, radius is not scaled
Error message if R0 is
programmed for APPR/DEP LN or
APPR/DEP CT
Contour elements with length 0
are ignored. The approach/depar-
ture movements are calculated
for the first and last valid contour
element
HEIDENHAIN | TNC 620 | User's Manual for Setup, Testing and Running NC Programs | 10/2018
iTNC 530
Effective in the machine coordinate
system
M143 does
delete the entry
not
in the ROT column in the preset
table; but only in the NC program;
reactivating the corresponding
preset table line activates the
deleted basic rotation
Error message
Tool radius 0 and compensation
direction RR are assumed
An error message is issued if a
contour element with length 0 is
programmed after the APPR block
(relative to the first contour point
programmed in the APPR block)
For a contour element with
length 0 before a DEP block, the
iTNC 530 does not issue an error
message, but uses the last valid
contour element to calculate the
departure movement
