Overview 49
You can configure this safety function to be similar to the STO (SSE with immediate
STO, stop category 0) or SS1 function (SSE with emergency ramp, stop category 1).

SSE is also activated in certain FSO fault reaction situations, see
Safe brake control (SBC)
This safety function provides a safe output for controlling external safety brakes.
When you use the SBC function with other safety functions of the FSO module, it is
always combined with the drive STO function. That is, the SBC function is activated
before, at the same time with, or after the drive STO function, and also when an
internal fault occurs as it activates STO.
Note:
With an internal fault, the STO and SBC are activated simultaneously.
STO function and SSE with immediate STO
In these safety functions, you can configure the SBC function to be activated before,
at the same time with, or after the drive STO function. See sections:
•
on page
,
•
•
SSE with immediate STO, SBC after STO
•
SSE with immediate STO, SBC before STO
on page
When you use an encoder, you can also configure the SBC function to be activated at
a user-defined speed limit with STO and SSE functions when drive is coasted with
STO immediately. See sections
•
STO with speed limit activated SBC
on page
•
SSE with immediate STO, with speed limit activated SBC
on page
.
Note
: The SBC is activated also when the drive STO is activated at zero speed in the
SSE and SS1 functions.
Note
: The FSO module activates the SSE function after trip limit hits in the SLS and
SMS functions.
As a result, this activates the drive STO and SBC functions (for more
information, see section
on page
). Make sure that
you dimension the brake correctly for these situations.
