To change the precision level, key in a desired precision level (1
to 10), then press the

key on the MDI panel.

When the precision level is changed, a RMS value is obtained
from the velocity-emphasized parameter set and
precision-emphasized parameter set for parameter modification.
For the modified parameters, see the description of the
machining parameter tuning.

If there is an axis in addition to the currently displayed axes,
press page key

If the tool life management B function is enabled (bit 4 (LFB) of
parameter No. 6805 = 1), the following parameters can be used to
display arbitrary groups and remaining set values.
•

If bit 5 (TGN) of parameter No. 6802 = 1

An arbitrary group is displayed on the list and group editing

screens.

•

If bit 3 (GRP) of parameter No. 6802 = 1

Remaining set values are displayed on the group editing screen.

The group editing screen always displays H and D codes.

The T series is provided with two tool change types, turret type and
ATC type. For the T series, displays vary depending on which tool
change type is in use.
If the turret type is in use (bit 3 (TCT) of parameter No. 5040 = 0)
•

Neither the H code nor the D code is used; neither is displayed.

•

No arbitrary group can be used; no arbitrary group is displayed.

If the ATC type is in use (bit 3 (TCT) of parameter No. 5040 = 1)
•

The D code is displayed on the group editing screen.

•

If the tool life management B function is enabled (bit 4 (LFB) of
parameter No. 6805 = 1) and bit 5 (TGN) of parameter No. 6802
= 1, arbitrary groups are displayed on the list and group editing
screens.

If the tool life management B function is enabled (bit 4 (LFB) of
parameter No.6805 = 1) and bit 3 (GRP) or parameter No. 6802 = 1,
remaining set values are displayed on the group editing screen.

Tool life management (list screen) (15-inch display unit)

This screen can display the life management status of all tools in tool
groups and whether the life of the tool groups has expired. It also
enables you to set tool life counters and clear execution data.

Procedure

Press function key

Press vertical soft key [NEXT PAGE] several times to display
soft key [TOOL LIFE].

Press vertical soft key [TOOL LIFE].

- Contents of (A)

(A) displays tool group numbers and an override value. If there is no
tool group to display, ****, instead of tool group numbers, is
displayed.
NEXT GROUP:

Tool group number for which life counting is started by the next
M06 command.

USING GROUP:

Tool group number for which life counting is currently under
way.

SELECTED GROUP:

Tool group number for which life counting is currently under
way or life counting has been performed most recently.

COUNT OVERRIDE:

“1.0TIMES” is displayed if the tool life counter override signal is
disabled (bit 2 (LFV) of parameter No. 6801 = 0).

NOTE

If arbitrary group numbers are enabled, NEXT
GROUP, USING GROUP, and SELECTED GROUP

rather than the tool group number.

- Contents of (B)

(B) displays the set life value, the current content of the tool life
counter, and the registered tool numbers (in the order they are used)
for each tool group. If the life count type is specification by duration,
the measurement unit used in displaying and specifying set life values
and tool life counter values is selected according to the setting of bit 0
(FCO) of parameter No. 6805 as listed below.

Bit 0 (FCO) of parameter No. 6805

Measurement unit used in displaying and specifying

set life values and tool life counter values

1 minute 0.1 minutes

The following table lists the prefixes used with tool numbers.

Tool status

Tool in use

Tool not in use

Life remaining

No indication

Skip

Life expired

NOTE

1 The tool life counter indicates the count value for the tool

indicated with @.

2 If bit 3 (EMD) of parameter No. 6801 = 0, a tool number

remains prefixed with @

even if the life of the tool has

expired until another tool is selected.

3 If bit 3 (EMD) of parameter No. 6801 =1, the following

differences can occur depending on the type of the life
counter in use.

•

If the life counter type is specification by duration, the

prefix is changed to “*” (life expired) as soon as the tool
life expires.

•

If the life counter type is specification by count, the

counter is incremented by one at the end of a program
(such as M02 or M30). So, the prefix is not changed to
“*” (life expired) even if the tool life counter matches the
life value. The symbol “*” (life expired) appears when
the tool life count is incremented after the CNC is reset.

4 If bit 2 (ETE) of parameter No. 6804 = 1, the symbol “*”

indicating the expiration of the life of the last tool appears
on the tool life management screen when the life counter
for the last tool of the tool group of interest matches the life
value. This way, the information about the last tool in the
FOCAS2 or PMC window indicates that the life of the tool
has expired if the tool change signal TLCH <Fn064.0> is 1.

If arbitrary group numbers are enabled, an arbitrary group number is
displayed in the parentheses beside the tool group number. If no
arbitrary group number is specified, “********”

is displayed instead.

Fig. 12.3.28.1 (b) Displaying arbitrary group numbers

Arbitrary group numbers are enabled by setting the following
parameters.

•

The tool life management B function is enabled (bit 4 (LFB) of

parameter No. 6805 = 1).

•

Arbitrary group numbers are enabled (bit 5 (TGN) of parameter

No. 6802 = 1).

•

The current tool change type is ATC (bit 3 (TCT) of parameter No.

5040 = 1).

•

The tool life management B function is enabled (bit 4 (LFB) of

parameter No. 6805 = 1).

•

Arbitrary group numbers are enabled (bit 5 (TGN) of parameter

No. 6802 = 1).

- Contents of (C)

(C) displays tool group numbers for which a tool change signal has
been issued.
If there are so many tool group numbers that all the numbers cannot be
displayed, some are omitted, and “

” is displayed instead.

If there is no tool group number in need of change, “****” is
displayed.

NOTE

If arbitrary group numbers are enabled, a tool group
number in need of change is represented with an
arbitrary group number rather than the tool group
number.

Setting data on the list screen

Tool life management data can be specified in the reset state (both the
OP and RST signals are “0”). However, setting bit 1 (TCI) of
parameter No. 6804 to 1 enables tool life management data to be
specified even during automatic operation (the OP signal is “1”).

NOTE

for

USING GROUP or NEXT GROUP settings:

1) During automatic operation (OP signal = “1” and

bit 1 (TCI) of parameter No. 6804 = 1), only the
tool life counter can be changed.

2) In the reset state (OP signal = “0” and RST signal

“0”), the following editing operation stops life
management because it cannot be continued.
- Clearing execution data

Procedure

- Setting the tool life counter

The tool life counter can be set with a value, using the following
methods.
Method 1
1

Place the cursor on the tool life counter for a desired tool group.

Enter the value from the keypad.

Press horizontal soft key [INPUT].

Method 2
1

Place the cursor on the tool life counter for a desired tool group.

Enter the value from the keypad.

3 Press

key.

- Clearing execution data

All existing execution data for a tool group selected by the cursor can
be cleared as follows:
1 Place the cursor on the tool group whose execution data you

want to clear.

Press horizontal soft key [ERASE].

Press horizontal soft key [EXEC].

NOTE

Setting bit 4 (GRS) of parameter No. 6800 to 1
enables execution data for all registered tool groups
to be cleared.

- Selecting tool groups

Tool groups can be selected using the following methods.
Method 1
1

Enter a tool group number from the keypad.

Press soft key [NO.SRH

]

NOTE

If arbitrary group numbers are enabled, a tool group
is selected by searching for an arbitrary group
number rather than the tool group number.
