Tool life count override signals *TLV0 to *TLV9 <Gn049.0 to Gn050.1>

[Classification] Input signal

[Function] If the tool life count type is specified by duration, the life count can be overridden by

setting bit 2 (LFV) of parameter No. 6800 = 1. Ten binary code signals are available, and
they correspond to override values as follows:

Override value =

{2i

Vi}

times

Keep the override values within the range stated above.

Where, if *TLVi is 1, Vi = 0
if *TLVi is 0, Vi = 1
Therefore, each signal has the following weight:

Example:

If *TLV7, *TLV6, and *TLV3 are 0, the override value is calculated as follows:
12.8 + 6.4 + 0.8 = 20.0
So, the life count is multiplied by 20.

If all signals are 1, the override value is 0. So, set an override value within the range
from 0 to 99.9 in steps of 0.1.

If 99.9 times is exceeded, the actual override value is clamped by 99.9 times.

[Operation] The actual cutting time obtained by life counting specified by duration is multiplied by

the override value specified by these signals, and the multiplication result is assumed to
be the count time for tool life management. For example, let the override value be 0.1,
and the actual cutting time be 1000 seconds. Then, the tool life count time is assumed to
be 100 seconds.

Tool life arrival notice signal TLCHB <Fn064.3>

[Classification] Output signal

[Function] If the tool life management B function is enabled (bit 4 (LFB) of parameter No. 6805 = 1),

specifying a remaining life value to be used till selection of a new tool enables the tool
life arrival notice signal to be issued when life counting shows that the remaining life
value of a group (life value minus life counter value) becomes lower than or equal to the
remaining life setting, in order to inform in advance that the tool life will expire soon.
By bit 4 (ARL) of parameter No. 6802, it is possible to select whether to output the tool
life arrival notice signal for each tool or the last tool in the group.
Bit 3 (GRP) of parameter No. 6802 can be used to specify which remaining life setting
(that is, one specified in parameter Nos. 6844 and 6855 or one registered as tool life
management data) to use.

[Output cond.] The signal is set to 1 if:

Remaining life (life value - life counter value)

≤

remaining life setting

provided that bit 7 (RMT) of parameter No. 6802 = 0

Remaining life (life value - life counter value) =

remaining life setting

provided that bit 7 (RMT) of parameter No. 6802 = 1

The signal is reset to

0 if

Remaining life (life value - life counter value)

remaining life setting

provided that bit 7 (RMT) of parameter No. 6802 = 0

Remaining life (life value - life counter value)

≠

remaining life setting

provided that bit 7 (RMT) of parameter No. 6802 = 1

NOTE

1 The signal changes when life counting is performed.
2 When using a life count override, reset bit 7 (RMT) of parameter

No. 6802 to 0.

3 When the life count is specified by duration, the unit of the

remaining life and remaining life setting to be compared varies
depending on the life count interval (bit 0 (FCO) of parameter No.
6805). If the tool life is counted every second, the unit of the values
to be compared is one minute; if the tool life is counted every 0.1
second, the unit of the values to be compared is 0.1 minute.

If bit 7 (CTB) of parameter No. 6803 is 1, this signal can be set to 0 when an operation
such as the following is performed.
-

Clears the execution data on the list screen of tool life management.

Deletes all tool group data at a time, adds a tool number, or deletes tool data on the
edit screen of tool life management.

Clears the execution data by the tool change reset signal TLRST <Gn048.7>.

Registers, changes, or deletes all tool life management group data by the G10
command.

Executes the FOCAS2 cnc_clrcntinfo function (which clears the tool life counter or
tool information).

Replaces a tool with a tool of which life is not managed by the M06 command.

Tool life counting disable signal LFCIV<Gn048.2>

[Classification] Input signal

[Function] Disables tool life counting for selected tools.

[Operation] If the signal turns to 1, the control unit behaves as explained below.

No life counting is performed for selected tools.

NOTE

The tool life counting disable signal LFCIV<Gn048.2> is valid if bit
6 (LFI) of parameter No. 6804 is 1.

Tool life counting disabled signal LFCIF<Fn093.2>

[Classification] Output signal

[Function] Informs that tool life counting is disabled for selected tools.

[Output cond.] The signal becomes 1 when:

Tool life counting is disabled because the tool life counting disable signal LFCIV is

The signal becomes 0 when:
-

Tool life counting is enabled because the tool life counting disable signal LFCIV is

Number of remaining tools notification signal TLAL <Fn154.0>

[Classification] Output signal

[Function] Informs that the number of remaining tools in the group selected with a T code command

is equal to or less than the setting of parameter No. 6846.

[Output cond.] The signal becomes 1 when:

The number of remaining tools in the group selected with a T code command is
equal to or less than the setting of parameter No. 6846.

The signal becomes 0 when:
-

A value is input to parameter No. 6846.

Using a G10 command, registration is performed that involves the erasure of all life
management data groups.

Using a T code command, a group is selected in which the number of remaining
tools is greater than the setting of parameter No. 6846.

The signal also becomes 0 when any of the following is executed in the group that has
caused the number of remaining tools notification signal TLAL to be generated.
-

Clearing of execution data, using the tool change reset signal TLRST <Gn048.7>.

Change and deletion of life management data, using a G10 command.

Batch deletion of tool groups from the group edit screen of tool life management,
addition of tool data to the screen, and deletion from the screen.

Clearing of tool execution data from the group edit screen of tool life management.

Clearing of execution data from the list screen of tool life management.

Execution of any of the FOCAS2 functions below.

(cnc_clrcntinfo, cnc_deltlifegrp, cnc_deltlifedt, cnc_instlifedt, cnc_wrt1info,

cnc_wrt2info, cnc_wr1tlifedata, cnc_wr1tlifedat2, cnc_wr2tlifedata)

NOTE

1 This signal is used in the M series only.
2 If the setting of parameter No. 6846 is 0, the number of remaining

tools notification signal TLAL is not output.

Example)

If three tools are registered in a group, and the number of remaining tools is set to 1
(parameter No. 6846 = 1), the timing chart of the number of remaining tools
notification signal TLAL is as shown in Fig. 11.5 (c).

The number of remaining tools notification signal TLAL is output at the same time
as the T code for the third tool.

[Data type] Bit path

#1 TSM

In the tool life management function, life counting is performed as follows when more

than one offset is specified:
0:

Counting is performed for each tool number.

Counting is performed for each tool.

#2 LVF

When the life value is counted by duration in the tool management function or tool life

management function, tool life count override signals *TLV0 to *TLV9 <Gn049.0 to
Gn050.1> are:
0:

Not used.

Used.

#3 EMD

In the tool life management function, the mark "*" indicating that the life has expired is

displayed when:
0:

The next tool is used.

The life has just expired.

NOTE

If this parameter is set to 0, the "@" mark (indicating that the tool is
in use) is kept displayed unless the next tool whose life has not
expired is used. If this parameter is set to 1, marks are displayed in
different ways depending on the life count type.

If the life count type is the duration specification type, the "*" mark
(indicating that the life has expired) appears when the life has
expired. If the life count type is the count specification type, one
count is not assumed until the end of the program (M02, M30, and so
on). Therefore, even when the life value and the tool life counter
value match, the "*" mark (life has expired) does not appear. The "*"
mark (life has expired) appears when the tool is used again by a tool
group command (T code) or tool change command (M06) issued
after the CNC is reset.

#7 M6E

When a T code is specified in the same block as M06:

The T code is treated as a back number or the group number to be selected next.

Which number is assumed depends on the setting of bit 7 (M6T) of parameter No.
6800.

Life counting for the tool group starts immediately.

The tool change signal is not output.

The tool change signal is output and the automatic operation stop state is entered..

If the life count is specified by use count and this parameter 1, the tool change signal
TLCH <Fn064.0> is output and the automatic operation becomes a stopped state if there
is a tool group whose life is expired when the M99 command is specified.

11. TOOL FUNCTIONS

B-64693EN-1/01

- 2016 -

If the life count type is the duration specification type, the automatic operation becomes a
stopped state if the life of at least one tool group has expired.

If the life count is specified by use count, after the M99 command is specified, a tool
group command (T code) selects, from a specified group, a tool whose life has not
expired, and the next tool change command (M06) increments the tool life counter by
one.

If the life count is specified by use count, when a tool group command (T code) is
specified after the M99 command is specified, a tool whose life has not expired is
selected from a specified group, and the tool life counter is incremented by one.
When the tool change type is the ATC type (bit 3 (TCT) of parameter No. 5040 = 1), the
same specifications as for the M series apply.

#1 TCO

#2 E17

When an attempt is made to write tool information from PMC window, completion
code 13 (REJECT ALARM) is returned.

△

: Tool information cannot be cleared.

NOTE

When tool information of a tool being used (marked with "@") in the
group being used or to be used next or tool information of the most
recently used tool (marked with "@") in a group that is neither the
group being used nor the group to be used next is cleared, the life
counter is reset to 0.
It is possible to modify tool information of a tool in the group to be
used next. However, because tool selection is already completed,
the selected tool does not change even when the tool information is
modified.

This parameter has no influence on modifications to tool information
by edit operations from the tool life management screen.

#3 GRP

Management data of tool life arrival notice signal TLCHB <Fn064.3> is:

NOTE

When the tool life arrival notice signal function is used, bit 4 (LFB) of
parameter No. 6805 must be set to 1 to enable the tool life
management B function.

#4 ARL

Tool life arrival notice signal TLCHB <Fn064.3> of tool life management is:

Output for each tool.

Output for the last tool of a group.

This parameter is valid only when bit 3 (GRP) of parameter No. 6802 is set to 1.

#5 TGN

In the tool life management function, the optional group number function is:

Not used.

Used.

NOTE

When the optional group number function is used, bit 4 (LFB) of
parameter No. 6805 must be set to 1 to enable the tool life
management B function.

In lathe systems, the optional group number function can be used if
the tool change type is the ATC type (bit 3 (TCT) of parameter No.
5040 = 1).

#6 TSK

If the count type in tool life management is the duration type, then when the last tool of a

group is skipped by a signal:
0:

The count value for the last tool equals the life value.

The count value for the last tool remains unchanged.

#7 RMT

Tool life arrival notice signal TLCHB <Fn064.3> is turned 1 and 0 as follows:

The signal is turned 1 if the remaining life value (the life value minus the life
counter value) is smaller than or equal to the remaining life setting. The signal is
turned 0 if the remaining life value (the life value minus the life counter value) is
greater than the remaining life setting.

The signal is turned 1 if the remaining life value (the life value minus the life
counter value) is equal to the remaining life setting. The signal is turned 0 if the
remaining life value (the life value minus the life counter value) is not equal to the
remaining life setting.

NOTE

When using the life count override feature, set bit 7 (RMT) of
parameter No. 6802 to 0. When the life count is specified by duration,
the unit used for determining the result of comparison between the
remaining life and the remaining life setting varies depending on the
life count interval (bit 0 (FCO) of parameter No. 6805). If the life is
counted every second, the comparison is made in units of 1 minute; if
the life is counted every 0.1 second, the comparison is made in units
of 0.1 minute.
