Information about Safety Integrated Stop F for this axis
Bit 0 set:
Bit 1 set:
System variable $VA_STOPSI
Axis-specific system variable that contains the present stop. For a value of 4, a STOP E is
active for this axis.
System variable $A_STOPESI
Global system variable that with a value not equal to 0 indicates that a Stop E is active for one
particular axis.
System variable $VA_SAFE_TYPE
Information about the active safety operating mode of this axis:
= 0:
= 1:
= 2:
System variable $A_INSI[1...192]
The status signals of the NCK monitoring channel can be used in the NCK-SPL using these
system variables. Each of the system variables $A_INSI[1...192] can be assigned any safety-
related output signal or the AND logic operation of several signals using axis-specific MD
$MA_SAFE_xxx_OUTPUT. These system variables can only be read by the user program.
Parameterizing example:
$MA_SAFE_CAM_PLUS_OUTPUT[0] = 04010101H
⇒ the SGA "SN1+" can be evaluated in the SPL using the system variable $A_INSI[1].
Programming example:
; copying an SGA from the internal SPL interface into the ext. SPL
interface
N1010 IDS = 01 DO $A_OUTSE[1] = $A_INSI[1]
These system variables can only be read by the user program.

In the crosswise data comparison between NCK and drive an actual value
error was detected.
In the crosswise data comparison between NCK and drive - an error was
detected and the delay time – up until a STOP B
($MA_SAFE_STOP_SWITCH_TIME_F) is initiated – is either running or has
expired.
Note: The bit is only set if a delay not equal to 0 is configured.
No Safety Integrated motion monitoring active
Safety Integrated NCK-integrated motion monitoring active
Safety Integrated drive-integrated motion monitoring with SIC/SCC coupling active
