Parameter settings 39
Parameters for the SSE function
These parameters are related to the Safe stop emergency (SSE) function of the FSO
module. The safety functions described in this manual do not use this function, but the
FSO module can activate the SSE function in internal fault situations.
I/O parameters
For digital inputs, set the diagnostic pulse setting to
On
. For indication lamps, set the logic
state of the corresponding digital output to
Active high
.

Description
SSE.13 SSE function
Immediate
STO
or
Emergency
ramp
Sets the type of the SSE function.
Immediate STO
: The FSO module activates the drive STO
function immediately after the SSE request.
Emergency ramp
: The FSO module first ramps down the motor
speed and when the speed is below the zero speed limit
(parameter
) it activates the STO
function. SAR0 parameters define the deceleration ramp (for
more information, see the FSO module user’s manual). See
also the Note on page
For the +Q979 option, ABB has set this parameter to value
Immediate STO
at the factory. Adjust the default value when
necessary.
Note
: The default value after factory reset is
Emergency ramp
.
Always check this parameter after factory reset.
SBC usage
SBC.15 SSE/SS1 SBC speed
0 rpm
Sets the absolute speed below which the FSO module activates
the brake (SBC) while ramping.
0 rpm
: This feature is not in use.
In this manual, we assume that you do not use a brake. If you
do, you must take care of its on/off control by the FSO module
and change this and other settings. See the FSO module user’s
manual.

In the safety functions described in this manual, the emergency
stop button is configured to this digital input by default. Make
sure that this value corresponds to the actual wiring. See the
circuit diagrams of the delivery.
SAFEIO.38 DI X114:2 diag
pulse on/off
On
Sets the diagnostic pulse of digital input X114:2 on or off.
On
: The input monitors that it receives test pulses.
In the safety functions described in this manual, the emergency
stop reset button is configured to this digital input by default.
Make sure that this value corresponds to the actual wiring. See
the circuit diagrams of the delivery.
