TNC 360/TNC 335 Update information No. 3 1-1
Update Information No. 3
Software version 11 for software types 260 02 and 280 49 was released at the end of January 1994.
Software version 10 was not released for general distribution.
The following improvements were made since version 9:
•
Machine parameter 7411 defines whether during execution of the TOUCH-PROBE block the
current compensation values for probe length and radius should be taken from the central tool
file or from the calibration process.
MP7411 = 1 : Probe length and radius values from the tool file
MP7411 = 0 : Probe length and radius values from the calibration process
MP 7411 is also effective for tool length compensation in the digitizing cycles. This machine
parameter was already available in version 08, but it was not documented.
•
Machine parameter MP7225 was introduced for automatic generation of NC blocks in the
PROGRAMMING AND EDITING mode. With the "actual position capture" key (teach-in) it is now
possible to generate a positioning block in plain language dialog (not in ISO mode) with a
maximum of 3 axes and without feed rate, radius compensation or M-functions. This positioning
block is inserted below the currently addressed block in the selected NC part program. The
current actual position values become the nominal position values. The axis is selected in the
dialog "AXIS SELECTION =" in the MOD operating mode. Here up to 3 out of 4 axes can be
selected by pressing the corresponding axis keys.
MP7225 = 1 : Block generation with the actual-position-capture key (teach-in)
MP7225 = 2 : Block generation with the actual-position-capture key or with the PLC marker
M2829 (the marker is reset by the NC)
MP7225 = 0 : No block generation or axis selection possible.
•
If the machine parameters are erased, the RS-232-C/V.24 interface is now preset to FE mode.
•
PLC inputs I160 to I175 (HR 332 handwheel) now generate signal edges. The positive edge is
assigned to markers M1660 to M1675, the negative flank to markers M1860 to M1875.
•
If machine parameter MP7641, Bit 2 = 1, the interpolation factor for the handwheel can be set
both from the keyboard as well as from PLC module 9036. If Bit 2 = 0, the machine parameter
functions as before (input either from the keyboard or from PLC module 9036).
•
The NC saves the code number entered in the MOD mode in Doubleword D276.
•
Machine parameter MP810 defines the modulo value for reducing the position values of the
auxiliary axes. Machine parameter MP7470 has no effect on auxiliary axes. Rotary axes as NC
axes are always reduced to the range 0° to 359.999°. Machine parameter MP810 was already
available in version 08, but it was not documented.
