Sets the monitoring method that is used in
SLS activation.
Time
or
SLS activation monit-
oring method
SLSx.03
Time monitoring: The drive (parameter 23.13
Deceleration time 1 or 23.15 Deceleration
time 2) defines the deceleration ramp and
it is monitored with parameter SLSx.04 SLS
time delay.
Ramp
Ramp monitoring: SAR1 parameters define
the deceleration ramp and monitoring limits.
See parameters 200.112, SARx.21,
SARx.22 and SARx.02.
For option +Q965, ABB sets this parameter
to value Ramp at the factory. Adjust the de-
fault value when necessary.
Sets the SLS monitoring time after which
the FSO module activates the SLS monitor-
ing after the SLS request. This parameter
is relevant only if time monitoring is used,
see parameter SLSx.03 SLS activation
monitoring method.
4000 msSLS time delaySLSx.04
Note: With time monitoring, when Monitoring
active and Modoff delay time is selected,
SLSx.04 and SLSx.06 time must be set
shorter than STO.14, otherwise STO is not
activated due to limit hit when drive modula-
tion is lost with SLS function.
Selects the fault reaction in case the drive
modulation is lost during the SLS decelera-
tion ramp, when SLS is activated from speed
which is higher than SLS limit speed.

For more information, see FSO module
user's manual.
Note: If encoder feedback is used, paramet-
er SLSx.05 has no effect.

SLSx.06
Note: SLSx.06 time must be set shorter than
STO.14, otherwise STO is not activated due
to limit hit when drive modulation is lost with
SLS function.
Note: If encoder feedback is used, paramet-
er SLSx.06 has no effect.
Sets the digital input that is connected to
the primary input of the SLS function with
limits 1.
DI X113:4 & X114:4SLS1 input ASLSx.11
For option +Q965, ABB has configured the
SLS request signal to these digital inputs at
the factory.
Sets the SLS1 negative speed limit that trips
the drive.

SLSx.13
Adjust the default value to meet the motor
in use.
Note: The difference between the SLS trip
limit and the corresponding SLS limit
(200.22 SLS1 limit negative) must be at
least 0.1 rpm.
