EXTERNAL
DATA INPUT (EDO THROUGH
ED15, EDSA THROUGH
EDSD, EDSA, O THROUGH
EDSA2, EDCL, EREND, ESEND) lNPUTS/OUTPUTS
Generally, the external tool compensation C and external work
coordinate system shift functions must be activated by specifying a
given M code in an appropriate location on the part program and
turning on the data request input EDCL by that M code.

TOOL
LIFE CONTROL
(TLA1
THROUGH
TLA16, TLTM, TLSKP,
TLRST,
TLCH1 AND TLCH2)
lNPUTS/OUTPUTS
The tool life control function enters the following into the control:
the information on tool life (how long a tool is serviceable or how
many workplaces a tool can cut), the tool numbers of tool groups of
the same type and the compensation
numbers to be used.
This
makes it possible, by simply specifying
the T code for tool life
control in the part program, for the control to control that T code
according to the machining
time and the number of workplaces
entered.
Described here are only the signals associated with this function.
For the program and other information, refer to "YASNAC J50L
Instruction Manual (TOE-C843- 12.20)."
This function uses the following inputs/outputs:
~Tool replacement completion tool group number inputs —TLAI 1,
TLA12, TLA 14, TLA18, and TLA21.
. Tool skip input — TLSKP
. Tool replacement request outputs — TLCH 1 and TLCH2
It is also needed to make a registration of the following information
through the program tape or CNC operator's panel MDI operation:

In addtion, there are settings for registering compensation numbers
and other
information.
Since
they have no relation
to the
input/output, the explanation is omitted.
(1) Tool Replacement
Complete
Tool Group Number
Inputs
(TLA1,
TLA2,
TLA4,
TLA8,
AND TLA16)
and Tool
Replacement Complete Input (TLRST)
These inputs inform the control
of the completion
of tool
replacement
after the replacement
of the tools of the group
number whose life has terminated.
Set the tool group number of tool replacement
complete
to
TLAI, TLA2, TLA4, TLA8, and TLA16 according to Table 19.24,
and close TLRST input.
When the replacement of the tools of the group number whose
life has terminated
is all completed,
tool replacement
request
outputs TLCH 1 and TLCH2 are opened.

1: Closed, O:Open
(2) Tool Skip Input (TLSKP)
This input is used to replace registered tools before their lives
terminate.
When TLSKP input is closed in the automatic feedhold state
(STL and SPL outputs are open), the processing that the service life
of the currently used tool has terminated is performed within the
controller.
Then the new tool is specified
by the following
T
command.
