Example value Description
DI X113:2 & X114:2 Sets the digital input that is connected to
the primary input of the SLS function with
limits 1.
For option +Q966, ABB has configured the
SLS request signal to these digital inputs at
the factory.
-250 rpm Sets the SLS1 negative speed limit that trips
the inverter unit.
Adjust the default value to agree with the
motor.
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.
250 rpm Sets the SLS1 positive speed limit that trips
the inverter unit.
Adjust the default value to agree with the
motor.
Note: The difference between the SLS trip
limit and the corresponding SLS limit
(200.23 SLS1 limit positive) must be at least
0.1 rpm.
DO X114:7 Sets the digital output that is connected to
the primary output of the SLS1 function.
Active when the SLS monitoring is on.
For option +Q966, ABB has configured the
SLS indication signal to this digital output at
the factory.
2000 ms Sets the target time for the stop ramp SAR1
that is used in the SLS function. Adjust the
default value when necessary.
Target time = The time in which the inverter
unit decelerates the motor(s) from speed
200.202 SAR speed scaling to zero.
Note: With value 0 ms, the inverter unit uses
the emergency stop ramp set by inverter
unit parameter 23.23. In this case, the FSO
module also monitors the actual ramp (ramp
monitoring or time monitoring).
Time monitoring: This value has no effect
in the operation. The inverter unit (parameter
23.13 Deceleration time 1 or 23.15 Deceler-
ation time 2) defines the deceleration ramp.
Ramp monitoring: Adjust the default value
when necessary.
