Note: The FSO module has a factory reset button. The factory reset button clears the
configuration and sets the parameters to the factory default values. These values are not
the same as the pre-set values in an FSO module that was ordered as an option (with a
plus code). You cannot restart the drive with the factory default values. If you do a factory
reset of the FSO module, you must reconfigure the FSO module and set all applicable
parameters. For more information on the factory reset, see the FSO module user's manual.
When using SS1, SLS or SMS safety functions: The FSO module activates the STO function
if the motor speed hits a ramp monitoring limit during the deceleration ramp. The FSO
module activates the SSE function if the motor speed hits a trip limit during SLS or SMS
monitoring. Thus, you must also configure the STO and SSE functions.
Follow the configuration steps described in the FSO module user’s manual, chapter
Configuration.
There are parameters that you must always set and parameters that are related to certain
safety functions only. These tables list all the parameters that you must check and set for
option +Q965. The example values are applicable only to option +Q965.
￭ General parameters
These parameters are common to all safety functions.

Automatic: You do not need to push a reset
button after switching on the FSO module.
The FSO module generates the acknow-
ledgement 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.
Selects the digital input for the acknowledge-
ment signal when parameter FSOGEN.41

FSOGEN.42
In the safety functions described in this
manual, parameters FSOGEN.41 Power-up
acknowledgement and STO.02 STO acknow-
ledgement are set to Automatic, and this
digital input is not used. The safety functions
are configured not to require a reset/acknow-
ledgement of the safety function after power-
up or the removal of the safety function re-
quest.
