13.15 Selecting the Axes for Generating

L Blocks (not TNC 410, only
Conversational Dialog)

The axis selection input field enables you to define the current tool
position coordinates that are transferred to an L block. To generate a
separate L block, press the ACTUAL-POSITION-CAPTURE soft key.
The axes are selected by bit-oriented definition similar to
programming the machine parameters:

13.16 Axis Traverse Limits, Datum

Display

The AXIS LIMIT mod function allows you to set limits to axis
traverse within the machine’s actual working envelope.

Possible application:
to protect an indexing fixture against tool collision.

The maximum range of traverse of the machine tool is defined by
software limit switches. This range can be additionally limited
through the AXIS LIMIT mod function. With this function, you can
enter the maximum and minimum traverse positions for each axis,
referenced to the machine datum. If several traverse ranges are
possible on your machine, you can set the limits for each range
separately using the soft keys LIMIT SWITCH (1) to LIMIT SWITCH
(3) (not TNC 410).
