If the total number of values set in parameter No. 5024 for the individual paths exceeds
the number of compensation values usable in the entire system, or 0 is set in parameter
No. 5024 for all paths, the number of compensation values usable for each path is a value
obtained by dividing the number of compensation values usable in the entire system by
the number of paths.
Tool compensation values as many as the number of compensation values used for each
path are displayed on the screen. If tool compensation numbers more than the number of
compensation values usable for each path are specified, alarm PS0115, “VARIABLE NO.
OUT OF RANGE” is issued.
For example, 64 tool compensation sets are used, 20 sets may be allocated to path 1, 30
sets to path 2, and 14 sets to path 3. All of 64 sets need not be used.

5028

Number of digits of an offset number used with a T code command

[Input type] Parameter input

[Data type] Byte path

[Valid data range] 0 to 4

Specify the number of digits of a T code portion that is used for a tool offset number
(wear offset number when the tool geometry/wear compensation function is used).
When 0 is set, the number of digits is determined by the number of tool compensation
values.
When the number of tool compensation values is 1 to 9: Lower 1 digit
When the number of tool compensation values is 10 to 99: Lower 2 digits
When the number of tool compensation values is 100 to 999: Lower 3 digits

[Example] When an offset number is specified using the lower 2 digits of a T code, set 2 in

parameter No. 5028.
Txxxxxx yy
xxxxxx : Tool selection
yy : Tool offset number

In tool management function, set 4 in this parameter to set 4-digit number in parameter
No.13265.

NOTE

A value longer than the setting of parameter No. 3032 (allowable
number of digits of a T code) cannot be set.

11.1.4

Extended Tool Selection Function

Overview

In lathe system machines, tools are changed mainly with the following two methods:

(1) With a turret holding multiple tools, tools are changed by turning the turret (T command).
(2) With an automatic tool changer (ATC), tools are changed by using both cartridge indexing (T

command) and tool change (such as M06) commands.

To support the tool change method explained in (2) above, the following tool selection specifications
apply to this function:
<1> Tool compensation by a T command is disabled. This means that the T command performs auxiliary

functions only.

<2> Tool compensation is enabled by using a G code instead of the T command. In this case, the

following types of tool compensation are enabled:

Tool length compensation

Tool offset (compensation equivalent to that of a T command in the case of turret rotation type)

Explanation

Selecting a tool change method

Bit 3 (TCT) of parameter No. 5040 selects a tool change method.
This changes the way for specifying tool compensation.
This parameter setting has influence on the range in the Table 11.1.4 (a) :

T command operation

(1) When bit 3 (TCT) of parameter No. 5040 is 0

The T command performs an auxiliary function and tool compensation.
The code signal issued to the machine is the T command value except the last 1 to 3 digits.
For example, suppose that the following command is issued when 2 is set in parameter No. 5028 (the
number of digits comprising the offset number in the T code command):
T0313 ;
The T code signal sent to the machine indicates 03.
The tool compensation number, indicated by the lowest 2 digits, is 13.

(2) When bit 3 (TCT) of parameter No. 5040 is 1

The T command performs an auxiliary function only.
In this case, the code signal issued to the machine is the T command value.
For example, suppose that the following is specified:
T0313 ;
The T code signal issued to the machine is 0313. The T code signal is not affected by the setting of
parameter No. 5028 (the number of digits comprising the offset number in the T code command).
The tool compensation number is not affected by this command.

Tool compensation

(1) When bit 3 (TCT) of parameter No. 5040 is 0

The T command performs tool compensation.

(2) When bit 3 (TCT) of parameter No. 5040 is 1

The T command does not perform tool compensation.
To provide tool compensation, specify G43.7 D_.
Tool compensation is performed in the same way as with the T command when bit 3 (TCT) of
parameter No. 5040 is 0.

Compensation number of tool compensation

(1) When bit 3 (TCT) of parameter No. 5040 is 0

The lowest 1 to 3 digits of the T command are used. The number of digits is set in parameter No.
5028.

When tool geometry/wear compensation is enabled (bit 6 (NGW) of parameter No.8136 is 0), tool
geometry compensation and wear compensation may also be assigned different compensation values
by setting bit 1 (LGN) of parameter No. 5002.

For details, see Section "TOOL FUNCTIONS OF LATHE SYSTEM".

(2) When bit 3 (TCT) of parameter No. 5040 is 1

Except that a compensation number is specified with a D command, the same operation as (1) above
is performed.

Compensation number of tool-nose radius compensation

Same as for tool compensation described above.

Specification of G43, etc.

(1) When bit 3 (TCT) of parameter No. 5040 is 0

G codes of group 23 such as G43 cannot be specified.
Specifying such a G code results in an alarm PS0366, “IMPROPER G-CODE IN TURRET
METHOD”.

(2) When bit 3 (TCT) of parameter No. 5040 is 1

G codes of group 23 such as G43 can be specified. The following G codes can be specified:

G43/G44: Tool length compensation

G43.7:

Tool compensation

Specify a compensation number with D_. The D code is specified in the same way as for tool
compensation and tool-nose radius compensation.

The reverse meanings can be set for G43/G44 and G43.7 by setting bit 4 (TLG) of parameter No.
5040.

Tool compensation memory

As the compensation amount used by the functions listed below, only the value set in Z on the tool
compensation memory screen is used, Values such as values set for the X, R, and Y-axis offsets are
ignored.

G43/G44: Tool length compensation

As the compensation amount used in the following function, the values set for the X, Z, and Y-axis
offsets on the tool compensation memory screen are used:

G43.7: Tool compensation

Limitation

Switching between tool compensation mode and another compensation mode

In the tool compensation (G43.7) mode, a command such as a tool length compensation command
(G43/G44) cannot be specified. Similarly, in a mode such as the tool length compensation mode
(G43/G44), tool compensation (G43.7) cannot be specified.
Specifying such a command results in the alarm PS0368, “OFFSET REMAIN AT OFFSET
COMMAND”.
To switch between compensation types, specify G49 to cancel the current compensation mode before
setting another compensation mode.

Multiple repetitive canned cycle

When a multiple repetitive canned cycle is executed with bit 3 (TCT) of parameter No. 5040 set to 1, note
the following:

CAUTION

1 When a G71 to G76 command is specified in the FS15 tape format, a value such

as the depth of cut is specified with a D code. In this case, a D command
specified after G71 to G76 is assumed to be the depth of cut. For example,
suppose that the command shown below is specified. In this case, the D
command <1> is assumed to be the tool compensation number, and the D
command <2> is assumed to be the depth of cut.
Example:
D10 G71 P_Q_ U_ W_ D7000 F_ S_;
<1> <2>

2 In the operation of G71 to G73, a G code such as G43 and a D command

specified in the finish figure blocks (the portion enclosed by the sequence
numbers specified with P_ and Q_) are ignored, and the compensation amount
set when the G71 to G73 block is specified becomes valid.

Changing bit 3 (TCT) of parameter No. 5040

WARNING

Before changing the setting of bit 3 (TCT) of parameter No. 5040, cancel the
offset. If the setting is changed while the offset is applied, the subsequent offset
operation may not be performed correctly or an alarm PS0368 occurs.

11.1.5

Automatic Alteration of Tool Position Compensation (T
Function)

Overview

After cutting tools are changed manually, entering the tool number of a new tool enables the previous tool
position compensation values (tool geometry and wear compensation) to be changed to those for the new
tool.

Details

After changing cutting tools manually, place the CNC in the JOG or HNDL (INC), or REF mode, enter
the tool number of a new tool as a manual tool compensation tool number signal MTLN <Gn068,
Gn069> or MT8N <Gn525-Gn528> from the PMC, and set the compensation command signal MTLC
<Gn067.0> to

“

”

. The CNC will read the tool number and change the previous tool position

compensation values to those for the specified tool. Upon completion of the compensation value change,
the compensation completion signal MTLA <Fn061.5> is output.

Four BCD digits are used to specify the manual tool compensation tool number MTLN <Gn068, Gn069>.
If it is necessary to specify the manual tool compensation tool number with a number exceeding 4 digits,
use MT8N <Gn525-Gn528> to specify it with 8 BCD digits. Which size to use can be selected using bit 7
(MTL8D) of parameter No. 11400. The same rules as for the T code command in automatic operation are
applied in specifying how many digits, 4 or 8, to use as the geometry or wear compensation numbers
(parameter No. 5028).
This function is available only if the CNC is in the JOG, HNDL, or REF mode.
In any other operation mode, during automatic operation (running, pause, or stop), in the tool-nose radius
compensation mode, (G41/G42 mode), setting the compensation command signal MTLC to

enable compensation.
If compensation is unavailable, the compensation completion signal MTLA does not become
