Tool skip signal TLSKP <Gn048#5>
[Classification] Input signal
[Function] Skips a tool whose life has not expired and selects the next tool forcibly. One
of the following methods can be selected by setting bit 3 (SIG) of parameter No.
6800:
(i) Specifying a group number by using the tool group number selection signals
(SIG = 1)
Specify the group number of the tool to be skipped by using the tool group
number selection signals (TL1 to TL512), then set the tool skip signal to "1".
The next T code command will then select the next tool in the group for which
the skip is specified.
(ii) Not specifying a group number by using the tool group number selection
signals (SIG = 0)
Set tool skip signal TLSKP to "1" without specifying any group number. The
group of the currently selected tool is then assumed to be specified.
The next T code command will select the next tool in the group for which the
skip is specified.
When tool skip signal TLSKP is set to "1" for the last tool, tool change signal
TLCH is set to "1".
[Operation] When this signal is set from "0" to "1", the control unit operates as follows:
- Among the tools whose lives have not expired in the group for which a skip
operation is specified, the smallest tool number in the tool life management
table is marked with "#". When the group is specified again by a T code
command, the marked tool is skipped, and the next new tool is selected.
When tool skip signal TLSKP is set to "1" for the last tool, tool change signal
TLCH is set to "1".
CAUTION
Tool skip signal TLSKP can be sent even in the automatic operation
start state (when the STL signal is "1"), but a tool selection from a
group by a T command is made when the command is buffered.
This means that after the command is buffered, inputting tool skip
signal TLSKP does not select the next tool. Therefore, when tool
skip signal TLSKP is input in the automatic operation start state (the
STL signal set to "1"), buffering must be suppressed so that the signal
is set from "0" to "1" with no tool selected.
New tool select signal TLNW <Fn064#1>
[Classification] Output signal
[Function] Notifies the PMC that a new tool is selected from a group. This signal can be
used when, for example, the tool length offset value of a newly selected tool is to
be measured automatically when the tool is selected.
[Output condition] The signal is set to "1" when:
