How does SLS function in detail?
1. The inverter detects the selection of SLS using a fail-safe input.
2. SLS allows a motor to reduce its possibly inadmissibly high speed within a defined time.
3. SLS monitors the absolute value of the actual velocity.
In addition, you can parameterize SLS so that SLS limits the velocity to values below the
monitoring threshold.
Note
As an alternative to control via terminals, there is also an option to parameterize the SLS
without selection function. In this case, the SLS function is permanently active after POWER
ON.
Select SLS with the motor switched on
As soon as the inverter detects the selection of SLS via a fail-safe input, the following happens:
