￭ 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.
Description Example value Name Index
Sets the type of the SSE function. Immediate STO
or Emergency
ramp SSE function SSE.13
Immediate STO : The FSO module activates the drive
STO function immediately after the SSE request (stop
category 0).
Emergency ramp : The FSO module first ramps down
the motor speed and when the speed is below the zero
speed limit (parameter
FSOGEN.51 or FSOGEN.52 ) it
activates the STO function (stop category 1). SAR0
parameters define the deceleration ramp (for more
information, see the FSO module user’s manual).
SBC usage
Sets the absolute speed below which the FSO module
activates the brake (SBC) while ramping. 0.0 rpm SSE/SS1 SBC speed SBC.15
0.0 rpm : The feature is not in use.
In the safety functions described in this manual, this
feature is not used. Make sure that the value is
0.0 rpm .
￭ Parameters for the SS1 function
Set these parameters only if you want that the FSO module activates the SS1 function in
overtemperature situations (stop category 1).
Description Example value Name Index
Activates or deactivates the SS1 function and shows
the version of the SS1 function. Version 1 SS1 activity and ver-
sion SS1.01
Version 1 : Activates version 1 of the SS1 function. For
more information, see the FSO module user’s manual.
Sets the digital input that is connected to the primary
input of the SS1 function. STO: None
SS1: DI X113:1
& X114:1
SS1 input A SS1.11
If you set this parameter to DI X113:1 & X114:1 , set
parameter STO.11 to None .
Sets the digital input that is connected to the secondary
input of the SS1 function. None SS1 input B SS1.12
Sets the method used for the SS1 monitoring. Adjust
the default value when necessary. SS1-t or SS1-r SS1 type SS1.13
Time monitoring (SS1-t): The FSO module monitors
that a user-defined deceleration time limit is not ex-
ceeded. (See parameter
SS1.14 .)
Ramp monitoring (SS1-r): The FSO module monitors
that the motor decelerates along a user-defined stop
ramp. (See SAR1 ramp parameters
200.112 , SARx.21 ,
SARx.22 and SARx.02 .)
