Function TNC 620 iTNC 530
Circle programming with polar
coordinates The incremental rotation angle
IPA
and the direction of rotation
DR
must have the same sign.
Otherwise, an error message will
be issued
The algebraic sign of the direction
of rotation is used if the sign
defined for
DR
differs from the one
defined for
IPA
Tool radius compensation on
circular arc or helix with angular
length = 0 The transition between the
adjacent elements of the arc/helix
is generated. Also, the tool axis
motion is executed right before
this transition. If the element is
the first or last element to be
corrected, the next or previous
element is dealt with in the same
way as the first or last element to
be corrected The equidistant line of the arc/
helix is used for generating the
tool path
Compensation of tool length in the
position display The values
L
and
DL
from the tool
table and the value
DL
from the
T
block are taken into account in the
position display
The values

SLII Cycles 20 to 24:
Number of definable contour
elements Max. 16384 blocks in up to 12
subcontours Max. 8192 contour elements
in up to 12 subcontours, no
restrictions for subcontour
Define the working plane Tool axis in
T
block defines the
working plane
The axes of the first positioning
block in the first subcontour
define the working plane
Position at end of SL cycle With the
posAfterContPocket
(no. 201007)
parameter, you can define
whether the end position is
above the last programmed
position, or whether the tool
moves to clearance height in
the tool axis
If the tool moves to clearance
height in the tool axis,
both coordinates must be
programmed with the first
traverse movement
With MP7420, you can define
whether the end position is
above the last programmed
position, or whether the tool
moves only to clearance height
in the tool axis
If the tool moves to clearance
height in the tool axis,
one coordinate must be
programmed with the first
traverse movement
