Update Information No. 15
The following software was released for the TNC 416:
Software 286 18x-02 was released in April 99 (no additional functions)
Software 286 18x-03 was released in April 99 (no additional functions)
Software 286 18x-04 was released in February 2000
The following software was released for the TNC 406:
Software 280 62x-9 was released in March 1999 (no additional functions)
Software 280 62x-10 was released in February 2000.
In the software 286 18x-04 and 280 62x-10 the following additions were made:
• New Cycle 14 Contour
Cycle 14 enables you to move continuously in the working plane in a freely programmable,
closed contour with programmed feed rate (not gap-controlled) and simultaneously erode in the
tool axis (gap-controlled), and plunge to a programmable depth.
If this depth is reached when a certain percentage (PRC) of the programmed contour length is
attained, the cycle ends.
Conditions for the contour program:
The erosion axis programmed in Cycle 14 must not appear in the contour program.
The programmed contour must be closed. This means that the contour must end at the point at
which it begins.
The starting point of the contour should be in the contour center so that the contour can be
scaled with Cycle 11.
When the cycle ends, the erosion axis remains at the final depth and does not retract as it does,
for example, in Cycle 17.
Example:
CYCL DEF 14.0 CONTOUR GEOMETRY
CYCL DEF 14.1 IZ-1 M36 (IZ-Qnn)
CYCL DEF 14.2 PGM CONTOUR1
CYCL DEF 14.3 PRC=90 (PRC=Qnn)
• During a reference run with the direction keys, traverse continues in manual mode after the
reference mark has been evaluated.
• New Q parameter Q164
The minimum undersize UNS of the maximum power stage is loaded after Q164 during
execution of the generator cycle.
• If a program was interrupted with ext./int stop and restarted with NC Start, then an incremental
positioning after a GOTO is always started from the current machine position.
