20 Parameter settings
Follow the configuration steps described in the FSO module user’s manual, chapter
Configuration .
There are parameters that you must set always and parameters that are related only to
certain safety functions. These tables list all the parameters that you must check and set
for the Q950. The example values apply only to the Q950.

General parameters
These parameters are common to all safety functions.

Parameters for the STO function
These parameters are related to the STO function of the FSO module. The FSO module
can activate the STO function in internal fault situations.
Index Name Example
value Description
FSOGEN.21 Motor nominal
speed
1500 rpm Sets the nominal motor speed. Adjust the default value to
meet the ratings of the motor in use.
FSOGEN.22 Motor nominal
frequency
50 Hz Sets the nominal motor frequency. Adjust the default value to
meet the ratings of the motor in use.
FSOGEN.41 Power-up
acknowledgement
Automatic Sets the power-up acknowledgement method of the FSO
module.
Automatic : You do not need to push a reset button after
switching on the FSO module. The FSO module generates
the acknowledgement signal automatically after the power-up.
Manual : The FSO module reads the external
acknowledgement signal through the digital input defined by
parameter
FSOGEN.42 .
Make sure that the value is Automatic.
FSOGEN.42 Acknowledgement
button input
None Selects the digital input for the acknowledgement signal when
parameter
FSOGEN.41 Power-up acknowledgement or
STO.02 STO acknowledgement has value Manual .
In the safety function described in this manual, parameters
FSOGEN.41 Power-up acknowledgement and STO.02 STO
acknowledgement have value Automatic , and this digital input
is not used. The safety function is configured not to require a
reset/acknowledgement of the safety function after power-up
or the removal of the safety function request.
Index Name Example
value Description
STO.02 STO acknowledgement Automatic Sets the acknowledgement method used in the STO, SSE and
SS1 functions.
Automatic : The FSO module generates the STO
acknowledgement signal automatically, and the user does not
have to press a reset button (see parameter
FSOGEN.42
Acknowledgement button input ).
Note : The default value after factory reset is Manual . Always
check this parameter after factory reset.
STO.11 STO input A None Sets the digital input that is connected to the primary input of
the STO function.
The safety option described in this manual does not use this
function and the value must be
None .
Note : The default value after factory reset is
DI X113:1&X114:1 . Always check this parameter after factory
reset.
