AZR

  When no reference position is set, the G28 command causes: 

0:  Reference position return using deceleration dogs (as during 

manual reference position return) to be executed. 

1:  Alarm (PS0304) "G28 was specified when no reference position 

is set" to be displayed. 

 

NOTE 

 

When reference position return without dogs is 
specified, (when bit 1 (DLZ) of parameter No.1005 is 
set to 1) the G28 command specified before a 
reference position is set causes an alarm PS0304 to 
be issued, regardless of the setting of AZR. 

 

        # 4 

XIK

  When LRP, bit 1 of parameter No.1401, is set to 0, namely, when 

positioning is performed using non-linear type positioning, if an 
interlock is applied to the machine along one of axes in positioning, 
0:  The machine stops moving along the axis for which the interlock 

is applied and continues to move along the other axes. 

1:  The machine stops moving along all the axes. 
 

        # 7 

IDG

  When the reference position is set without dogs, automatic setting of 

the IDGx parameter (bit 0 of parameter No.1012) to prevent the 
reference position from being set again is: 
0: Not 

performed. 

1: Performed. 
 

NOTE 

 

When this parameter is set to 0, bit 0 (IDGx) of 
parameter No. 1012 is invalid.

  When a number with no decimal point is specified, the least input

When the increment system is IS-A, and bit 0 (DPI) of parameter No.

be 10 times greater than the least command increment.

[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  An address other than addresses 'A', 'B', and 'C' cannot 

be used as the address of a rotary axis used for the 
function for tool length compensation in a specified 
direction or the tool center point control function. 

3  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. 

 

Because of reserved words of custom macros, 
extended axis names that start with the following two 
characters cannot be used: 

 AB,AC,AD,AN,AS,AT,AX,BC,BI,BP,CA,CL,CO,US,WH,

WR,XO 

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

an argument.

plane) and a 3-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

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
