Modified functions 34059x-05
FZ and FU feed rate input possible in the Tool Call block, see
"Calling the tool data", page 258
With tool selection the control displays the XL and ZL columns
from the turning tool table in the pop-up window, see "Tool call",
page 686
The input range of the DOC column in the pocket table has
been expanded to 32 characters, see "Pocket table for tool
changer", page 255
Commands FN 15, FN 31, FN 32, FT and FMAXT from
predecessor controls no longer generate ERROR blocks during
import. When simulating or running an NC program with these
commands, the control interrupts the NC program with an error
message that helps you to find an alternative implementation
Miscellaneous functions M104, M105, M112, M114, M124,
M134, M142, M150, M200 - M204 from predecessor controls
no longer generate ERROR blocks during import. When
simulating or running an NC program with these miscellaneous
functions, the control interrupts the NC program with an error
message that helps you to find an alternative implementation,
see "Comparison: Miscellaneous functions", page 922
The maximum file size of files output with FN 16: F-PRINT has
been increased from 4 KB to 20 KB
The Preset.PR preset management is write-protected in
Programming operating mode, see "Saving presets in the table",
page 739
The input range of the Q parameter list for defining the QPARA
tab on the status display consists of 132 input positions, see
"Displaying Q parameters (QPARA tab)", page 105
Manual calibration of the touch probe with fewer pre-positioning
movements, see "Calibrating 3-D touch probes ", page 758
The position display takes into account the DL oversizes
programmed in the Tool Call block, selectable as an oversize of
the workpiece or tool, see "Delta values for lengths and radii",
page 241
In single block mode the control executes each point individually
with point pattern cycles and CYCL CALL PAT, see "Program
run", page 823
Rebooting the control is no longer possible with the
END
key
but with the
RESTART
soft key, see "Switch-off", page 718
The control displays the contouring feed rate in manual mode,
see "Spindle speed S, feed rate F and miscellaneous function
M", page 732
Deactivate tilting in manual mode is only possible via the 3D-
ROT menu, see "Activating manual tilting:", page 786
Machine parameter
maxLineGeoSearch
(no. 105408) has
been increased to max. 100000, see "Machine-specific user
parameters", page 882
The names of software options number 8, 9 and 21 have
changed, see "Software options", page 9
