The operation of the SS1-r function with speed limit activated SBC is described in the
time diagram and table below. For configuration, see section
with speed limit activated SBC
on page
A
SBC speed (parameter
): Speed limit below which the FSO activates the SBC
(brake) and drive STO functions while ramping.
B
SBC time to zero
(parameter
): Time from the SBC activation to the moment
when the safety function is completed and the SS1 completed indication (parameter
