Modified functions 77185x-02
The input range of the DOC column in the pocket table has
been expanded to 32 characters, see "Pocket table for tool
changer", page 219
Commands D15, D31 and D32 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 693
The maximum file size of files output with D16 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 531
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 89
Manual calibration of the touch probe with fewer pre-positioning
movements, see "Calibrating 3-D touch probes ", page 549
The position display takes into account the DL oversizes
programmed in the T block, selectable as an oversize of the
workpiece or tool, see "Delta values for lengths and radii",
page 207
In single block mode the control executes each point individually
with point pattern cycles and G79 PAT, see "Program run",
page 603
Rebooting the control is no longer possible with the END key
but with the RESTART soft key, see "Switch-off", page 516
The control displays the contouring feed rate in manual mode,
see "Spindle speed S, feed rate F and miscellaneous function
M", page 529
Deactivate tilting in manual mode is only possible via the 3D-
ROT menu, see "Activating manual tilting:", page 576
Machine parameter maxLineGeoSearch (no. 105408) has
been increased to max. 50000, see "Machine-specific user
parameters", page 658
The name of software option number 8 has changed, see
"Software options", page 9
