you dimension the brake correctly for these situations.
SS1 function and SSE with emergency ramp
In these safety functions, you can configure the SBC and STO combination to be
activated at a user-defined speed limit while ramping down to zero speed. See
sections
•
SS1 with speed limit activated SBC
and
•
SSE with speed limit activated SBC
on page
.
You can also define a delay so that the SBC is activated first at the user-defined
speed limit and the drive STO after the delay. See sections

SS1 with speed limit activated SBC, SBC before STO

Safely-limited speed (SLS)
This safety function prevents the motor from exceeding user-defined speed limits. If
the motor speed reaches the positive or negative SLS trip limit, the FSO module
activates the SSE function and the motor stops. See section
on page
.
Variable Safely-limited speed (SLS)
This safety function prevents the motor from exceeding user-defined speed limits.
With the Variable SLS function, the speed limits can be changed on the fly. The speed
limits are controlled from a safety PLC via the PROFIsafe communication bus. See
section
Variable Safely-limited speed (SLS)
and chapter
Safe maximum speed (SMS)
This safety function is used to protect the machine from too high speeds/frequencies.
You can configure it to be permanently on or off. If the motor speed reaches the
minimum or maximum SMS trip limit, the FSO module activates the SSE function and
the motor stops. There are two different versions of the SMS function. See sections

Prevention of unexpected start-up (POUS)
This safety function prevents the machine from starting accidentally. The POUS
function activates the drive STO function. See section
