SICK OLM100 User Manual

The default setting for the Speed F
ilter parameter is 10 mm and this must be taken into
account at the planning stage (see "Configuring speed limits", page 37).
WARNING
T
here is a risk of death or serious injury if the stopping distance is calculated incor‐
rectly.
b
Do not change the Speed Filter parameter.

delay time may be required depending on the drive system in

is the amount of time required by the drive system for a stop ramp. If after t
1
the
acceleration is not great enough owing to a fault, the torque will be deactivated (safe
torque off, STO - stop). If the optional safe brake control (SBC) (QA120) is linked to Flexi
Soft, this will be activated too.
NOTE
If t
he stopping time with safe torque off (STO) and safe brake control (SBC) is greater
than in the case of the standard stop ramp, the higher value must be used for T
PDS(SR)
.
13.4.1 Stopping time in the event of a drive fault
If the drive is faulty and the speed is not limited, the torque is deactivated and the
opt
ional safe brake control (SBC) is activated.

13.4.2 Flexi Soft cycle time
The cycle time of the Flexi Soft safety controller is dependent on the scope of the logic.
In t

of 8 ms.
