Machinle parameters / User-parameters
Machine parameters can be split into the following groups:
Machine-specific parameters
For prograrnming of e.g. rapid feeds, spindle speeds. Also for axis designation, counting direction and
linear compensation.
Machine parameters for optimization of the positioning loops
For optimising e.g. the trailing error (lag) and positioning behaviour.
Machine parameters for the integral PLC
For activation of, certain PLC-program sections or macros. !t is also possible to initiate special user-cycles.
Nominal values for a PLC-positioning routine can be stored. Further machine parameters permit a central
tool memory or the control of a toolchanger.
Machine parameters for adaptation of a data interface
In the EXT-mode of the RS-232-C (V.24)interface, data formats, control characters and transmission
protocols for peripheral units can be programmed.
Machine parameters for electronic handwheels and 3D-touch probe systems
An entry value corresponding to the connected handwheel version and a limitation of the sensitivity is
programmed. This prevents the influence of axis movement in the event of shocks.
For the 3D-touch probe system parameters such as the safety clearance, measuring feed and traverse
limitation are entered.
Machine parameters which affect NC-programming
Such parameters can be made accessible to the user as user-parameters. Selection and, if necessary, a plain
language designation via the PLC-program is made by the machine tool builder.
These can be parameters for:
.Selection of the dialogue language
.Selection 0.f the programming language
.Projection for graphics display in 3 planes
.For the cot-trot as a programming station with an inactive machine
.Overstep for pocket milling
.Scaling factor effective in 2 or 3 axes
.Adaptation of the RS-232-C (V.24)interface in the “EXT’‘-mode for data transmission units.
Initial commissioning procedure
The following procedure is applicable to machine commissioning:
1)
Determination of the parameters of the first group (see section 6.1)
2)
Filling lout of complete parameter list in the sequence demanded by the TNC 151/TNC 155 (see section 9)
3)
Entry of parameters into the control (see section 8.1.3)
4)
Optimisation of temporary parameters as per check-list (see section 8)
Erasing machine parameters
Code number 531210
With this, machine parameters can be erased easily. Moreover, the erasable markers Ml000 to M2000 are
reset.
