13.8 Axis Traverse Limits
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.
Axis Traverse Limits for Program Run
The maximum range of traverse of the machine tool is defined by
software limit switches. This range can be additionally limited
through the MOD function TRAVERSE RANGE MACHINE. With this
function, you can enter the maximum and minimum traverse
positions for each axis, referenced to the machine datum.
Working without additional traverse limits
To allow a machine axis to use its full range of traverse, enter the
maximum traverse of the TNC (+/- 30000 mm) as the traverse
range.
To find and enter the maximum traverse:
ú Select REF position display
ú Move the spindle to the positive and negative end positions of
the X, Y and Z axes.
ú Write down the values, including the algebraic sign.
ú To select the MOD functions, press the MOD key.
ú Enter the limits for axis traverse: Press the TRAVER-
SE RANGE MACHINE soft key and enter the values
that you wrote down as limits in the corresponding
axes. Confirm your entry with the ENT key.
ú
To exit the MOD function, press the END key.
The tool radius is not automatically compensated in the
axis traverse limit value.
The traverse range limits and software limit switches
become active as soon as the reference points are
traversed.
Axis Traverse Limits for Test Run
It is possible to define a separate „traverse range“ for the Test Run
and the programming graphics. Press the soft key TRAVERSE
RANGE TEST (2nd soft-key row), after you have activated the MOD
function.
In addition to the axis traverse limits, you can also define the
position of the workpiece datum referenced to the machine datum.
To save any values you have changed, press the ENT key.
