Safety Integrated Extended Functions6.7 Safely-Limited Speed (SLS)Safety Integrated98 Function Manual, 05/2010, A5E03264275A6.7.6 EPOS and Safely-Limited SpeedIf safe speed monitoring (SLS) will also be used at the same time as the EPOS positioningfunction, EPOS must be informed of the activated speed monitoring limit. Otherwise thespeed monitoring limit can be violated by the EPOS setpoint input. Through the SLSmonitoring, this infringement results in the drive being stopped and thus abandoning theplanned movement sequences. Here the relevant safety faults are output first, and only thenare the subsequent faults created by EPOS output.With its parameter r9733, the SLS function provides a setpoint limiting value which whencomplied with prevents the SLS limiting value from being infringed.This means that the setpoint limiting value in r9733 must therefore be transferred to the inputfor the maximum setpoint speed/velocity of EPOS (p2594), to prevent an SLS limiting valueinfringement as a result of the EPOS setpoint input. In this regard you must set the delaytime for SLS/SOS (p9551/p9351) so that the SLS only becomes active after the maximumrequired time for the speed to be reduced below the SLS limit. This required braking time isdetermined by the current speed, the jerk limit in p2574 and the maximum delay in p2573.Overview of important parameters● p2573 EPOS maximum deceleration● p2574 EPOS jerk limit● p2593 CI: EPOS LU/revolution LU/mm● p2594 CI: EPOS maximum speed externally limited● p9351 SI Motion SLS changeover delay time (Motor Module)● p9551 SI Motion SLS(SG) changeover delay time (Control Unit)● r9733(0.1) CO: SI Motion speed setpoint limit active
