STOP B is the subsequent stop of STOP F, which is activated after a parameterizable time. STOP F alone does not

SLS remains active during the braking phase, after which the system switches to SOS.

The table above specifies which stop response or safety function is set when a STOP is
triggered when a safety function is active. The STOPs are arranged here from left to right in
descending order of priority (STOP A-F).
No overall priority is assigned in the individual safety functions. SOS remains active, for
example, even if STO is requested. The safety functions that cause the drive to decelerate
(STO, SS1, SS2) are specified from top to bottom in descending order of priority.
If a field contains two entries, the stop responses and safety functions have the same
priority. Explanation:
● STOP A corresponds to STO
● STOP B corresponds to SS1
● STOP C corresponds to SS2
● When the SS2 function is active, STOP F results in subsequent stop B. SS2 remains
