Tool Skip Input (TLSKP)
Before a registered tool reaches the preset end of its useful life, this input causes the machine
to use a new tool.
When the TLSKP input is closed in the automatic operation pause state (when the STL and
SPL outputs are open), the control internally concludes that the currently used tool has reached
the end of its useful life, and designates a new tool upon receipt of the next T command.
Tool Replacement Request Output
When a program ends or the rest procedure is performed after all the registered tools having a
certain group number have reached the end of useful life, the TLCH output closes.
When this output is closed, note the affected tool group number displayed on the CRT and
carry out necessary tool replacement.
NOTE
While the tool replacement request output is closed, the automa-
tic mode automatic startup function is disabled.

35046) INPUTS AND OUTPUTS
(1) These inputs and outputs assure that the machine performs the following functions in re-
sponse to external inputs.
(a) External work number search input
A desired work number is chosen by externally selecting an appropriate program number
between 1 and 99999
(b) External tool offset input
Offset adjustments are made according to the external data input signal.
(c) External work coordinate system shift input
The work coordinate system shift amount data are corrected according to the external data
input signal.
Input/Output Signals For Inputting External Data
External data inputs (EDO #30300 to ED31 #30337)
These inputs are used for work No. input signal, offset input signal and work coordin-
ate system shift signal.
