Read/write operations for tool management data and cartridge management
table

The tool management data and cartridge management table can be read from and written to by using the
CNC/PMC data window library (FOCAS2). Therefore, a specific tool management system including all
available tool data not registered in the CNC can be built easily by using the OPEN CNC.

Similarly, the tool management data and cartridge management table can also be read from and written to
using the PMC window.

Tool management data of the tool being used as a spindle after a tool change operation performed by M06
and the tool being selected by specifying a T code can be read using a custom macro.

The user can modify tool management data by MDI from the tool management function screen of the
CNC. Addition, modification, and deletion of the above tool management data can be made from a part
program (G10). Such data can also be input to and output from external I/O equipment by using the ALL
I/O screen and tool management function screen.

G10 format

Addition, modification, and deletion are performed for the tool management data and cartridge
management table from programs.

If a format error is found in the commands from G10 L75/L76/L77 to G11, or if a value beyond the valid
data range is specified, alarm PS5312,” ILLEGAL COMMAND IN G10 L75/76/77” is issued. In such a
case, correct the program. Within the range from G10 to G11, no decimal point can be specified with any
address. If a decimal point is specified, alarm PS0007,” ILLEGAL USE OFDECIMAL POINT” results.

Input to and output from external equipment

Input to and output from external equipment are enabled only on the ALL IO screen or tool management
screen if the I/O unit number is 4, 6, or 7.

Caution

The total number of pots of all cartridges is normally 64. It can be expanded to 240 and 1000
optionally.

When pots are assigned to cartridges, the first cartridge has a top priority.

Example 1

When the maximum number of pots is 64

Parameter setting

First cartridge

Second cartridge

Third cartridge

Fourth cartridge

If the content of one of parameter Nos. 13220, and 13222 to 13251 is rewritten, tool management
data numbers of all cartridges are initialized to 0. This prevents conflict between tool management
data and the cartridge management table.

Example 2

If parameter No. 13220 is set to 30 when tool management data number 60 is set for pot number 1 of
cartridge 1, nonexistent tool data is regarded as being held in the pot.
-

When data is edited, its tool management data number blinks, and it is excluded from the data to be
searched for the next tool. In this case, you cannot modify the data by using the PMC or FOCAS2.
This condition is maintained until the edit mode ends.

The CNC does not perform tool life management for the tool attached at the
corresponding spindle position (the first to fourth spindle).

Life expiration signal TMFNFD<Fn315.6>

[Function] This signal indicates whether a valid tool whose life still remains is left among the tools

having the type number specified by a T code.

[Output cond.] This signal turns to

“

in the following cases:

When a T code is specified, the tools having the type number specified by the T
code include no valid tool whose life still remains.

NOTE

In this case, it is necessary for the PMC to stop the operation by
issuing an external alarm and request a tool change. If the selected
tool is used continuously with no alarm issued, the life of the tool is
counted up. The tool (cartridge and pot) selected by the CNC at
this time is a tool having the largest tool management data number
among the tools having a specified tool type number.

This signal turns to
