3.INPUTTING AND OUTPUTTING PARAMETERS THROUGH THE READER/PUNCHER INTERFACE B-63950EN/02

3.3.2 Inch/Metric Switching

For parameters dependent on inch/metric switching such as those for
length and feedrate, whether data is inch data or metric data is
specified by the input mode in the case of input from the MDI panel,
or by the keyword I or M prefixed to the data in the case of input from
an external I/O device. The keyword I or M is added also when data
is output from an external I/O device.
If the input mode or keyword differs from the actually used mode as
in a case where data input in the inch mode is used in the metric mode,
the CNC performs automatic data conversion. So, data need not be
converted according to a mode change. Moreover, when parameter
data is displayed, the data is converted according to the display mode.
However, when data is output from an external I/O device, the original
data is output according to the original keyword.

3.3.3 Bit Format

N ***** Q1 P ******** ;

A numeric value after N represents a parameter number.
Q1 indicates that the data is parameter data.
An 8-digit binary number after P represents the bit values (0/1) of a
parameter, with the first digit corresponding to bit 0 and the eighth
digit corresponding to bit 7.
Leading zeros may not be omitted.
A semicolon (;) marks the end of a block. (LF is used for the ISO
code, and CR is used for the EIA code.)

4.5 PARAMETERS OF READER/PUNCHER INTERFACE

To transfer data (programs, parameters, and so forth) to and from an
external input/output device through the I/O device interface
(RS-232-C serial interface), the parameters described below need to
be set.
The input/output device connected to a channel (such as RS-232-C
serial port 1 and RS-232-C serial port 2) can be selected by setting I/O
CHANNEL (parameter No. 0020). The specifications (input/output
specification number, baud rate, and the number of stop bits) of an
input/output device connected to each channel must be set in the
parameters corresponding to each channel beforehand.
For channel 1, two combinations of parameters to specify the
input/output device data are provided.
The following shows the interrelation between the input/output device
interface parameters for the channels.

I/O CHANNEL : Input/output device selection, or interface number for a

foreground input device

The CNC has the following interfaces for transferring data to and from
an external input/output device and the host computer:
Input/output device interface (RS-232-C serial ports 1 and 2)
Memory card interface
Data server interface
By setting bit 0 (IO4) of parameter No. 0110, data input/output can be

is established:
0: A movement is made at the reference position return feedrate FL.
1: Until a servo motor grid is established, a movement is not made

at the reference position return feedrate FL even if the
deceleration dog is pressed, but a movement is made at the rapid
traverse rate.

If the deceleration dog is released after a movement at the rapid
traverse rate and the deceleration dog is then pressed again and
released after the rotation axis makes one revolution, reference
position return operation is completed.
When this parameter is set to 0, the alarm (SW0090) "REFERENCE
POSITION RETURN FAILURE" is issued if the deceleration dog is
released before a servo motor grid is established.
If this alarm is issued, start manual reference position return at a
position sufficiently far away from the reference position.

# 1 ALZx In automatic reference position return (G28):

0: Reference position return is performed by positioning (rapid

traverse).
If no reference position return is performed after the power is

1012 IDGx

[Input type] Parameter input
[Data type] Bit axis

# 0 IDGx The function for setting the reference position again, without dogs, is:

0: Not inhibited.
1: Inhibited.
(The alarm (PS0301) is issued.)

NOTE

IDGx is enabled when the IDG parameter (bit 7 of

parameter No.1002) is 1.

If the function for setting the reference position

without dogs is used, and the reference position is
lost in absolute position detection for a cause, the
alarm (DS0300) is issued when the power is turned
on again.

If the operator performs reference position return,

as a result of mistakenly identifying the alarm as
that requesting the operator to perform a normal
reference position return, an invalid reference
position may be set. To prevent such an operator
error, the IDGx parameter is provided to prevent
the reference position from being set again without
dogs.

(1) If the IDG parameter (bit 7 of parameter

No.1002) is set to 1, the IDGx parameter (bit 0
of parameter No.1012) is automatically set to 1
when the reference position is set using the
function for setting the reference position
without dogs. This prevents the reference
position from being set again without dogs.

(2) Once the reference position is prevented from

being set for an axis again, without dogs, any
attempt to set the reference position for the
axis without dogs results in the output of an
alarm (PS0301).

(3) When the reference position must be set again

without dogs, set IDGx (bit 0 of parameter
No.1012) to 0 before setting the reference
position.

[Input type] Parameter input
[Data type] Byte axis
[Valid data range] 67,85 to 90

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.

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.

NOTE

1 When a multiple repetitive canned cycle for turning

is used, no character other than 'X','Y', and 'Z' can
be used as the address of the axis.

2 When 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.

3 In a macro call, no extended axis name can be

1022 Setting of each axis in the basic coordinate system

[Input type] Parameter input
[Data type] Byte axis
[Valid data range] 0 to 7

To determine a plane for circular interpolation, cutter compensation,
and so forth (G17: Xp-Yp plane, G18: Zp-Xp plane, G19: Yp-Zp
plane) and a three-dimensional tool compensation space (XpYpZp),
specify which of the basic three axes (X, Y, and Z) is used for each
control axis, or a parallel axis of which basic axis is used for each
control axis.
A basic axis (X, Y, or Z) can be specified only for one control axis.
Two or more control axes can be set as parallel axes for the same basic
axis.

Setting Meaning

0 Rotation axis (Neither the basic three axes nor a parallel axis )
1 X axis of the basic three axes
2 Y axis of the basic three axes
3 Z axis of the basic three axes
5 Axis parallel to the X axis
6 Axis parallel to the Y axis
7 Axis parallel to the Z axis

In general, the increment system and diameter/radius specification of
an axis set as a parallel axis are to be set in the same way as for the
basic three axes.

[Input type] Parameter input
[Data type] Byte path
[Valid data range] 0 to Number of controlled axes

The unit of some parameters common to all axes such as those for dry
run feedrate and single-digit F1 feedrate may vary according to the
increment system. An increment system can be selected by a
parameter on an axis-by-axis basis. So, the unit of those parameters
is to match the increment system of a reference axis. Set which axis
to use as a reference axis.

Among the basic three axes, the axis with the finest increment system
is generally selected as a reference axis.

rapid traverse rate (parameter No. 1420) is used,
regardless of the setting of parameter No. 1466.
When this parameter is set to 0, parameter No.
1466 is used as the feedrate for retraction. As
acceleration/deceleration used for retraction, only
acceleration/deceleration after interpolation is
used. Rapid traverse before look-ahead
interpolation and optimum torque
acceleration/deceleration are disabled.
