3.10.7 System variables for SINUMERIK 840D
The following system variables can only be used in combination with
SINUMERIK
programmable logic (SPL). A detailed description of the system variables is
provided in Chapter 4.4.2. .
Table 3-59 Overview of system variables
System variables Meaning
Actual position
$VA_IS [ Axis ] Safe actual position for Safety
Integrated
$AA_IM [ Axis ] Actual position for closed-loop control
$VA_IM [ Axis ]
Encoder actual value in the machine
coordinate system
Error status
$A_XFAULTSI The crosswise data comparison
between NCK and 611D of any axis
has detected an actual value error
$VA_XFAULTSI[Axis The crosswise data comparison for
name] this axis between NCK and 611D has
detected an actual value error
$VA_STOPSI Actual Safety Integrated Stop for the
particular axis
$A_STOPESI Actual Safety Integrated Stop E of any
axis
