Safe Stop 2 in an EPOS application
The SOS function is used to enable the Safe Stop 2 function to be used with EPOS.
The "intermediate stop" function (p2640 = 0) causes the axis to be stopped when the SOS
function is triggered. When making the settings under p2573 (maximum deceleration) and
p2645 (deceleration override) for the deceleration caused by EPOS, it is essential to ensure
the drive can be stopped within the delay time for SOS activation → SOS active
(p9551/p9351)..
Overview of important parameters (see SINAMICS S List Manual)
● p2573 EPOS maximum deceleration
● p2640 BI: EPOS intermediate stop (0 signal)
● p2645 CI: EPOS direct setpoint input/MDI, deceleration override
● p9351 SI Motion SLS changeover delay time (Motor Module)
● p9551 SI Motion SLS(SG) changeover delay time (Control Unit)
