NOTE

1 Creating one folder results in the

number of programs yet to be
registerable decreasing one.

2 The program storage size means

the maximum size of a program if
the program is the one and only
program registered.

3 If more than one program is

registered, the total size of
registerable programs reduces for
the following reason.
The FS0

-F Plus manage programs

in page units. The unit of program
storage is managed also in page
units. When a program is created,
as many pages as necessary to
store the program are secured, and
the program is stored on these
pages. Generally, the last program
storage page has an unused area
(Fig. 13.4). This unused area cannot
be used to store any other program.
For the sake of program
management, it is regarded as an
area in use.
The FS0

- C uses a similar way of

management, but the unit of pages
in it differs from that in the FS0

-F

Plus. So, if more than one program
is registered in the FS0

-F Plus, the

total program size of registerable
programs in the FS0

-F Plus differs

from that in the FS0

-C.

INCH/METRIC CONVERSION

Overview

Either inch or metric input (least input increment) can be switched by the following five methods.
-

G code(G20/G21)

SETTING (HANDY) screen/setting bit 2 (INI) parameter No. 0000

PMC Window

Programable parameter input(G10)

Custom macro variable #3005

Explanation

Switching method using a G code(G20/G21)

The unit of input data is switched by G20/G21. It switches to inch input by G20, and metric input by G21.
Please refer to the OPERATOR'S MANUAL (Common to Lathe System/Machining Center
System)(B-64694EN) for switching conditions of G20/G21.

Switching method using a SETTING (HANDY) screen/setting parameter

The unit of input data is switched by SETTING (HANDY) screen or setting bit 2 (INI) parameter
No. 0000. Please refer to the OPERATOR'S MANUAL (Common to Lathe System/Machining Center
System)(B-64694EN) for switching conditions.

Switching method using a PMC Window

The unit of input data is switched by writing setting data of PMC window (low speed type). Please refer
to the PMC Programming Manual (B-64513EN) for details.

Switching method using a programable parameter input(G10)

Setting bit 2 (INI) parameter No. 0000 is rewritten by the G10 command, and the unit of input data is
switched.

Switching method using a custom macro variable

The unit of input data is switched by system variable #3005.

Switching position

The unit of input data is switched at the reference position of the machine coordinate system origin. When
the bit 1 (INAx) of parameter No. 14000 set to 1, if an inch-metric switch command is executed at a
position other than the machine coordinate system origin (position = zero), the alarm PS5362,
“CONVERT INCH/MM AT REF-POS” is generated.

-

In case G code(G20/G21), it is possible to change the unit at the positions other than 0 of the
machine coordinate by the following settings.

(a) Setting bit 2 (IRFx) of parameter No. 14000 to 1 enables inch/metric conversion to be performed in

the reference position (parameter No. 1240). However, enable a function of workpiece coordinate
system (bit 0 (NWZ) of parameter No. 8136 is 0).

(b) Setting bit 0 (NIM) of parameter No. 11222 enables inch/metric conversion to be performed even in

positions other than the reference position. However, enable functions of workpiece coordinate
system and workpiece coordinate system preset (bit 0 (NWZ) of parameter No. 8136 is 0 and bit 1
(NWC) of parameter No. 8136 is 0).

In case SETTING (HANDY) screen or setting parameter or PMC Window, it is possible to change
the unit at the positions other than 0 of the machine coordinate by the following settings.

12. PROGRAM COMMAND

- 2037 -

(d) Setting bit 0 (NIM) of parameter No. 11222 and bit 3 (IMRx) of parameter No. 14000 enables

inch/metric conversion to limit in the reference position (parameter No. 1240). However, enable
functions of workpiece coordinate system and workpiece coordinate system preset (bit 0 (NWZ) of
parameter No. 8136 is 0 and bit 1 (NWC) of parameter No. 8136 is 0).

If an inch-metric switch command is executed at a position of the machine coordinate

system origin other than zero,

No alarm is issued.

Alarm PS5362, “CONVERT INCH/MM AT REF-POS” is issued.

#2 IRFx

An inch-metric switch command (G20, G21) at the reference position is:

Disabled.

Enabled.

NOTE

1 When this function is enabled for an axis, if an attempt to switch

between the inch and metric unit is made although the tool is not at
the reference position on that axis, an alarm PS5362 is issued, and
switching between the inch and metric unit is canceled. Be sure to
move the tool to the reference position by, for example, specifying
G28 before switching between the inch and metric unit.

2 This function enables the inch/metric switching commands (G20 and

G21) at the reference position. It does not enable the switching of the
setting input unit (bit 2 (INI) of parameter No.0000).

3 Switching between inch and metric by setting the setting input unit

(bit 2 (INI) of parameter No. 0000) is enabled only when the machine
coordinate of the first reference position is 0 (parameter No. 1240 is
0) and presence on the first reference position is assumed. For a
system in which the machine coordinate of the first reference position
is not 0, set this parameter to 1 and specify G20/G21 in the first
reference position to switch between inch and metric.

4 When this function is disabled, the switching is enabled only when

the machine coordinate of the first reference position is 0 (parameter
No. 1240 is 0) and presence on the first reference position is
assumed.

#3 IMRx

When bit 0 (NIM) of parameter No.11222 is set to 1, the reference position return before

commanding inch/metric conversion :
