(e) Input/output signals
Table 4.3.3.5 Input/Output Signals
(f) Display and setting of tool life control data
The tool life control data can be displayed by depressing the [T-LIFE] (f3) job soft key in
the [SET] process. On this screen, the tool life control data (tool numbers in a tool group,
offset number, life, number of use, etc.) can be changed by directly writing the data. The
data can be changed only while the automatic operation is suspended (reset status, single
block stop status) and not in the edit prohibited status.
(g) Specifying tool group
Tool group is specified by a T code. Tool group number is specified by the value set for
parameter pm4110 × 1000 + 1 to + 128. These numbers correspond to group 1 to group
128.
If the setting is “pm4110 = 5”: Tool groups T5001 to T5128 are set.
(3) Life count multiplication command
For counting the tool use data (distance, time), it is possible to specify the multiplying factor
in a program by specifying “G125 P***; [P: Life count multiplying factor (one digit to the
right of the decimal point)]”.
• G125 is a non-modal G code. Once “G125 P***” is specified, the life count multiply-
ing factor specified as P*** remains valid until the NC is reset or G125 is specified
again. The life count multiplying factor is returned to “1” when no P command, PO or
P1 is specified with G125.
• The life count multiplying factor is valid only when counting tool life in distance or
Contents of Signal Description
Tool-1ife count disregarded input
(TLCTN = #30127) If this input signal is “ON’ during the execution of the tool life con-
trol function, counting of the tool life is suspended.
Tool skip input
(TLSKP = #30126) If this input signal state changes from “’OFF” to “ON” during the
execution of the tool life control function, the tool life status is forci-
bly skipped.
pm4029 D1 = 0:
For the tool presently selected
pm4029 D1 = 1: For the tools in the specified group (TLGRP)
Tool group number input
(TGN = #30250 to #30257) Specifies the tool group number that is used for the tool skip input.
Tool change signal output
(TLCHA = #35087) When service life of all took in a tool group has expired, the tool
change signal status is set to “closed”.
New tool selection signal output
(TLCHB = #35086) When a new tool is selected in a tool group, if the life count data of
the new tool are “0“, this signal is output with a T code at the same
time.
