Modified functions 34059x-05
FZ and FU feed rate input possible in the Tool Call block ("Call tool
data", page 186).
With tool selection, the control also displays columns XL and
ZL from the turning tool table in the pop-up window ("Tool call",
page 497).
The input range of the DOC column in the pocket table has been
expanded to 32 characters ("Pocket table for tool changer").
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 ("Comparison: Miscellaneous
functions").
The maximum file size of files output with FN 16: F-PRINT has been
increased from 4kB to 20kB.
The Preset.PR preset table is write-protected in Programming
operating mode ("Saving the datums in the preset table").
The input range of the Q parameter list for defining the QPARA tab
on the status display consists of 132 input positions ("Displaying Q
parameters (QPARA tab)", page 84).
Manual calibration of the touch probe with less pre-positionings
("Calibrating a 3-D touch trigger probe ").
The position display takes into account the DL oversizes
programmed in the Tool Call block, selectable as an oversize of the
workpiece or tool ("Delta values for lengths and radii", page 173).
In single blocks, the control executes each point singly with point
pattern cycles and CYCL CALL PAT ("Program run", page 598).
Rebooting the control is no longer possible with the END key, but
with the soft key ("Switch-off", page 518).
The control displays the contouring feed rate in manual mode
("Spindle speed S, feed rate F and miscellaneous function M",
page 530).
Deactivate tilting in manual mode is only possible via the 3D-ROT
menu ("To activate manual tilting:", page 574).
The machine parameter maxLineGeoSearch has been increased
to a maximum of 100000 ("Machine-specific user parameters",
page 646).
The names of the software options #8, #9 and #21 have been
changed ("Software options", page 8).
