[Classification] Input signal
[Function] A tool which has not reached its lifespan may be changed by one of two
methods:
(i) Designate the group number for the tool by tool group number
selection signal then turn the tool skip signal TLSKP to “1”. The next
T-code command will pass over the current tool in the group for which
the skip was designated, and select the next tool.
(ii)Turn the TLSKP signal to “1” without designating a group number,
and the machine will skip to the next tool in the group currently in use.
Either of these methods is set using parameter SIG (No. 6800#3). Tool
life is counted from zero. When the TLSKP signal is “1” and the last tool
in the group is being used, the TLCH signal turns to “1”.
[Operation] When the signal is set to “1”, the control unit operates as follows:
· Selects the next tool in the group for which a skip is specified with the
next T code.
· Assumes the number of the group to which the current tool belongs.
CAUTION
The cycle start lamp signal (STL) and feed hold lamp signal
(SPL) must both be “0” before inputting the TLSKP signal.
[Classification] Output signal
[Function] Reports that a new tool of a certain group is selected.
This signal can be used when, for example, a compensation value is to be
measured automatically when a new tool is selected.
The new tool select signal is issued at the same timing as TF (tool function
strobe signal).
[Output condition] The signal is set to “1” when:
· A new tool of a certain group is selected.
The signal is set to “0” when:
· The completion signal is set to “1”.
