Explanation of machine data and setting data
2.2 Overview of the data
Range
from 42000 to 42999
from 43000 to 43999
Data Identifiers
The identifier specified in the data description is displayed on the HMI user interface; however,
if the data is addressed in the parts program, for example, the identifier of the relevant data
area must precede the data identifier (designator).
Identifier
$MM_
$MN_/ $SN_
$MNS_/ $SNS_
$MC_/ $SC_
$MCS_/ $SCS_
$MA_/ $SA_
$MAS_/ $SAS_
Characters

Note
Axis-specific data can also be addressed with the axis name as an index. The internal axis
identifier (AX1, AX2, AX3, etc.) or the identifier specified in MD10000
$MA_AX_CONF_NAME_TAB can be used as the axis name.
Example: $MA_JOG_VELO[Y1]=2000
The JOG velocity of axis Y1 is 2000 mm/min.
If the content of a machine data is a STRING (e.g., X1) or a hexadecimal value (e.g., H41),
the content must be enclosed in single quotation marks (e.g., 'X1' or 'H41').
Example: $MA_FIX_POINT_POS[0,X1]=500.000
The value 500 is assigned to the first fixed point position on axis 1.
Examples:
$MN_AUXFU_GROUP_SPEC[2]='H41'
Output instant in time of the auxiliary functions of the 3rd auxiliary function group.
