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).
Index Name
SS1.01 SS1 activity and ver-
sion
SS1.11 SS1 input A
SS1.12 SS1 input B
SS1.13 SS1 type
SS1.14 SS1-t delay for STO
SAR1 ramp settings
200.112 SAR1 ramp time to
zero
Example value Description
0.0 rpm Sets the absolute speed below which the FSO module
activates the brake (SBC) while ramping.
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.
Example value Description
Version 1 Activates or deactivates the SS1 function and shows
the version of the SS1 function.
Version 1: Activates version 1 of the SS1 function. For
more information, see the FSO module user's manual.
None Sets the digital input that is connected to the primary
input of the SS1 function.
STO: None Sets the digital input that is connected to the secondary
input of the SS1 function.
SS1: DI X113:4
If you set this parameter to DI X113:4, set parameter
STO.12
SS1-r Sets the method used for the SS1 monitoring. Adjust
the default value when necessary.
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
20000 ms Sets the monitoring delay after which the FSO module
activates the drive STO and SBC at the latest, if the
motor speed has not gone below the zero speed limit
(parameter
Time monitoring: This value sets the security delay that
the FSO module monitors. Adjust the default value
when necessary.
Ramp monitoring: This value has no effect in the oper-
ation.
2000 ms Sets the target time for the stop ramp SAR1 that is used
in the SS1 and function. Adjust the default value when
necessary.
The target time is the time in which the drive deceler-
ates the motor from the speed defined by parameter
200.202
Note: With value 0 ms, the drive uses the emergency
stop ramp set by drive parameter 23.23 (see section
