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
STO.02 STO acknowledge-
ment
STO.11 STO input A
Example value Description
50 Hz Sets the nominal motor frequency. Adjust
the default value to meet the ratings of the
motor in use.
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 acknow-
ledgement signal automatically after the
power-up.
Manual: The FSO module reads the extern-
al acknowledgement signal through the di-
gital input defined by parameter FSO-
GEN.42.
Make sure that the value is Automatic.
None Selects the digital input for the acknowledge-
ment 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 re-
set/acknowledgement of the safety function
after power-up or the removal of the safety
function request.
Example value Description
Automatic Sets the acknowledgement method used
in the STO, SSE and SS1 functions.
Automatic: The FSO module generates the
STO acknowledgement signal automatic-
ally, 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.
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.
