Loader Path

When the loader control function is used, the loader path can be used.

In the loader path, the servo axis can be used up to 3 axes. Other axis/spindle cannot be used.

The axis in the loader path is contained in the number of connected servo motors. Refer to Table1.1 (a)

for the maximum number of connected servo motors.

The axis in the loader path is not contained in the “Total number of control axes” and “Number of feed

axes”.

NOTE

"Function for loader control" is optional function. The number of the usable loader

path is different depending on the option composition.

1.2

SETTING EACH AXIS

1.2.1

Name of Axes

Overview

Each axis that is controlled by the CNC (including those controlled by the PMC) must be named.

To name an axis, select a desired character from among A, B, C, U, V, W, X, Y, and Z and set the

character as the first axis name character (parameter No. 1020).

NOTE

1 The same axis name cannot be assigned to more than one axis. (The same axis

name can be used on different paths.)

2 With the lathe system, when G code system A is used, neither U, V, nor W can be

used as an axis name. Only when G code system B or C is used, U, V, and W

can be used as axis names.

3 When a multiple repetitive canned cycle is used, only X, Y, or Z can be used as

the address of a target axis.

- Extended axis name

The extended axis name function can be used to use an axis name consisting of up to three characters.

To use an extended axis name:

<1> Enables the extended axis name function (bit 0 (EEA) of parameter No. 1000 is set to 1).

<2> Set the first character (A, B, C, U, V, W, X, Y, or Z) in parameter No. 1020 (first axis name

character).

<3> Set the second character (’0’ to ’9’ and ’A’ to ’Z’) in parameter No. 1025 (second axis name

character).

<4> Set the third character (’0’ to ’9’ and ’A’ to ’Z’) in parameter No. 1026 (third axis name character).

NOTE

1 If the second axis name character is not set for an axis, the third axis name

character is invalid.

2 When setting 0 to 9 for the second axis name character, do not set A to Z for the

third axis name character.

3 When an axis name ends with a numeric character, an equal sign (=) is required

to be specified between the axis name and the command value.

4 In a macro call, no extended axis name can be used as an argument.

5 If at least one axis in a path uses an extended axis name when bit 2 (EAS) of

parameter No.11308 is set to 0, subscripts (parameter No. 3131) cannot be used

for axis names in the path.

6 When G code system A is used for a lathe system, X, Y, Z, or C may be used for

the first axis name character of an axis. In this case, when a command containing

U, V, W, or H as the first axis name character is specified, it is used as the

incremental command for the corresponding axis.

7 In a multipath system, if an extended axis name is not used on a path or if bit 2

(EAS) of parameter No. No.11308 is set to 1 and subscripts (parameter No.

3131) are not set for axis names, the path number will automatically be the

subscript for axis names. To disable the display of axis name subscripts, set a

blank (32) of ASCII code in the parameter for specifying an axis name subscript.

NOTE

8 If the custom macro function is enabled, the same extended axis name as a

reserved word cannot be used. Such an extended axis name is regarded as a

reserved word.

Because of reserved words of custom macros, extended axis names that start

with the following combinations of two characters cannot be used:

An axis name (axis name 1: parameter No. 1020) can be arbitrarily selected from 'A', 'B',

'C', 'U', 'V', 'W', 'X', 'Y', and 'Z'. (When G code system A is used with the lathe system,

however, 'U', 'V', and 'W' are not selectable.) When bit 0 (EEA) of parameter No. 1000 is

set to 1, the length of an axis name can be extended to three characters by setting axis

name 2 (parameter No. 1025) and axis name 3 (parameter No. 1026) (extended axis

name).

For axis names 2 and 3, a character from '0' to '9' and 'A' to 'Z' of ASCII code can be

arbitrarily selected. However, the setting of axis name 3 for each axis is invalid if axis

name 2 is not set. Moreover, if a character from '0' to '9' is set as axis name 2, do not use a

character from 'A' to 'Z' as axis name 3.

Setting

When G code system A is used with the lathe system, and the character 'X','Y','Z', or 'C' is

used as axis name 1 of an axis, a command with 'U','V','W', or 'H' specified for axis name

1 represents an incremental command for the axis.

3 When the custom macro function is enabled, the same extended

setting axis name 2 and axis name 3. For axis names 2 and 3, a character from '0' to '9'

and 'A' to 'Z' of ASCII code can be arbitrarily selected. However, the setting of axis name

3 for each axis is invalid if axis name 2 is not set. Moreover, if a character from '0' to '9' is

If a multi-path system is used, no extended axis name is used within a path, or bit 2

(EAS) of parameter No. 11308 is set to 1 and no subscript is set for the axis names, then

the path number is automatically used as the subscript for the axis names. To disable the

display of axis name subscripts, set a blank (32) of ASCII code in the parameter for

specifying an axis name subscript.

NOTE

If even one axis in a path uses an extended axis name when bit 2

(EAS) of parameter No. 11308 is set to 0, subscripts cannot be

used for axis names in the path.

Example of setting an axis name

1.2.2

Increment System

Overview

The increment system consists of the least input increment (for input unit) and least command increment

(for output unit, machine unit). The least input increment is the least increment for programming the

travel distance. The least command increment is the least increment for moving the tool on the machine.

Both increments are represented in mm, inches, or degrees.

There are three types of increment systems as listed in Table 1.2.2 (a). A desired type can be set for each

axis using the corresponding bit 0 (ISA), or 1 (ISC) of parameter No. 1013.

The least input increment can be set to metric input or inch input using the G code (G20 or G21) or

setting parameter (bit 2 (INI) of parameter No. 0000).

The least command increment is set to either metric or inch system depending on the machine tool in

advance. Select the metric or inch system using bit 0 (INM) of parameter No. 1001 in advance.

Any combined use of the inch and metric systems is not allowed. There are functions that cannot be used

across axes with different increment systems (such as circular interpolation and cutter compensation).

NOTE

1 The unit (mm or inch) in the table is used for indicating a diameter value for

diameter programming (when bit 3 (DIA) of parameter No. 1006 is set to 1) or a

radius value for radius programming.

2 Even if the parameters bit 0 (ISA), or 1 (ISC) of parameter No.1013 is changed,

the tool offset unit is not changed. Set the tool offset unit by parameters bit 0

(OFA), or 1 (OFC) of parameter No.5042.

3 Some increment systems are unavailable depending on the model. For details,

refer to “DESCRIPTIONS” (B-64692EN).

High precision program command

Overview

In the program command to the axis address, the value that is one digit smaller than incremental system is

enabled to command and analysis.

Features) Workpiece composed of free-form surface can be reproduced in high precision

- Incremental system is not changed, but program command unit is distributed to high precision

- The high precision machining can be achieved with keeping the usage of the machine

In the machine of incremental system 1μm, the machining program 0.1μm is executable

Fig. 1.2.2.1 (a) Example in incremental system B

This function is enabled in all increment system (IS-A to C).

This function is activated when bit 0 (HPC) of parameter No.10478 is set to 1.
