(3) Tool Replacement Request Outputs (TLCH)
When a program end or reset operation is performed after the
ter-mination of the service lives of all registered tools belonging
to a tool group number, TLCH is closed.
When these outputs are closed, make sure of the tool group
number which is being displayed on the CRT screen and replace the
tools.
Note

automatic operation mode is disabled.
19.2.47 SKIP INPUT
If SKIP input is closed during the execution of move command by
G31 in the automatic operation mode, the control immediately stops
the movement and stores the coordinate value where SKIP input
changed from open to close. At this point, the block of G31
command is regarded to have been completed, and the following
block is taken up.
The coordinate value of the skip position is stored in the
following setting numbers:
#6568 --- X-axis coordinate value
#6569 --- Z-axis coordinate value
Note
1. The block of G31 command moves in the same way as
GO1. If parameter SKPFED (#60 19 D4) is set to “ 1, “ the
feed rate which is not specified in the part program but is
set to parameter G3 lF (#6232) is provided.
2. If SKIP input is not closed after the completion of the
block of G31 command, the following operation takes
place:
, When setting SKIPIN (#6004 DO) is set to “ 1,“ the
following block is executed.
. When setting SKIPIN (#6004 DO) is set to “O,” the alarm
state (alarm code “087”) is generated.
