If SLS shall be requested by a safe digital input, the configuration must be set accordingly, see 7.11.2 - Parameters
If the SLS state shall be displayed with the safe digital output, the configuration must be set, see 7.13.2 - Parameters .
If SLS shall be requested via safe fieldbus, the safe fieldbus must be activated, see 7.10.3 - Safe Fieldbus Configuration.
WARNING
SLS Speed Limit Configuration
The speed monitoring can be influenced by the speed computation time, the motor current and different
other effects in the motor sensor system, like wearing out, slider position, etc.
To make sure that the speed monitoring does not respond, the commanded target speed in the SLS should
be much lower than the selected SLS Speed Limit parameter.

Safety Fn State SLS 0 1A14h
Bool
-
SLS 0 active
Set if the SLS 0 safety function is active. The activation may be a result
from a demand of the Safety Application Process, or a demand from the
PROFIdrive on PROFIsafe Safety Function State Machines.
Cleared if the SLS 0 safety function is inactive.
This bit can also be accessed via UPID 1A06h bit 4.
Safety Fn State SLS 1 1A15h
Bool
-
SLS 1 active
Set if the SLS 1 safety function is active. The activation may be a result
from a demand of the Safety Application Process, or a demand from the
PROFIdrive on PROFIsafe Safety Function State Machines.
Cleared if the SLS 1 safety function is inactive.
This bit can also be accessed via UPID 1A06h bit 5
Safety Fn State SLS 2 1A16h
Bool
-
SLS 2 active
Set if the SLS 2 safety function is active. The activation may be a result
from a demand of the Safety Application Process, or a demand from the
PROFIdrive on PROFIsafe Safety Function State Machines.
Cleared if the SLS 2 safety function is inactive.
This bit can also be accessed via UPID 1A06h bit 6.
Safety Fn State SLS 3 1A17h
Bool
-
SLS 3 active
Set if the SLS 3 safety function is active. The activation may be a result
from a demand of the Safety Application Process, or a demand from the
PROFIdrive on PROFIsafe Safety Function State Machines.
Cleared if the SLS 3safety function is inactive.
This bit can also be accessed via UPID 1A06h bit 7.
Safety Fn State SLS
Selected
1A1Ch
Bool
-
SLS selected
The safety module has detected a request for one of the four SLS
instances.
This bit can also be accessed via UPID 1A06h bit 12.
