Parameters for the SSE function
These parameters are related to the Safe stop emergency (SSE) function of the FSO module.
The SLS and SMS functions activate the SSE function if the motor speed reaches a trip
limit during monitoring. 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.
Emergency ramp
: The FSO module first
ramps down the motor speed and when the
speed has reached the zero speed limit
(parameter FSOGEN.52), it activates the
STO function. SAR0 parameters define the
deceleration ramp (for more information,
see the FSO module user’s manual).
For the +Q965 option, ABB has set this
parameter to value
Immediate STO
at the
factory. Adjust the default value when ne-
cessary.
Note:
The default value after factory reset
is
Emergency ramp
. Always check this
parameter after factory reset.
Sets the method used for the SSE emer-
gency ramp monitoring. This parameter is
relevant only if parameter SSE.13 SSE
function is set to
Emergency ramp
.
Ramp or Time
SSE monitoring
method
SSE.14
Ramp
: SAR0 parameters define the emer-
gency ramp and monitoring limits (see
SAR0 ramp settings).
Time
: Parameter 200.102 SAR0 ramp time
to zero defines the emergency ramp and it
is monitored with parameter SSE.15 SSE
delay for STO.
For the +Q965 option, ABB has set this
parameter to value
Ramp
at the factory.
Adjust the default value when necessary.
Sets the SSE monitoring time after which
the FSO module activates the drive STO
function after the SSE request.
20000 ms
SSE delay for STO
SSE.15
This parameter is relevant only if parameter
SSE.13 SSE function is set to
Emergency
ramp
, time monitoring is used (SSE.14 SSE
monitoring method = Time) and the motor
speed does not follow the ramp.
Note:
This delay must be considered when
the total response time for the safety func-
tion is defined.
