Parameters related to the SSE function
These parameters are related to the Safe stop emergency (SSE)
function of the FSO module. The safety function described in this
manual does not use this function, but the FSO module can
activate the SSE function in internal fault situations
.
Index Name Example
value Description
SSE.13 SSE function Immediate
STO
1)
Sets the type of the SSE function.
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, it activates the STO
function (stop category 1). SAR0
parameters define the deceleration
ramp. For more information, see the
FSO module user’s manual.
Note : The default value after factory
reset is Emergency ramp . Always
check this parameter after factory
reset.
SBC usage
SBC.15 SSE/SS1 SBC
speed
0 rpm Sets the absolute speed below which
the FSO module activates the brake
(SBC) while ramping.
0 rpm: The feature is not in use.
In the safety function described in
this manual, this feature is not used.
Make sure that the value is
0 rpm .
See also section Mechanical brake
control on page 64 .
1)
With the FPTC module, the recommended value is Immediate STO, but
other safety functions in the FSO module can require that the value is
Emergency ramp. With both settings, the FSO module always activates the
drive STO function immediately in motor overtemperature situations (SMT
function activated).
