Which SGE/SGA are required for the test stop of external STOPs?
The following SGE/SGA can be used to perform the test stop for external STOPs:
NCK monitoring channel
Drive monitoring channel

Canceling stopping delay times

The specified transition times
SG → SBH
STOP C → SBH
STOP D → SBH
STOP E → SBH
define the time period from requesting a stop until switchover to a Safe Operating Stop. These
stopping delay times should be parameterized so that for the worst case scenario (maximum
velocity, low acceleration capability), the axis or spindle involved can stop within this time
