SLS reaction if modulation is lost with Monitoring and modoff delay time
disabled - modulation returns
The operation of the SLS function in case the modulation of the drive is lost during the
deceleration ramp with Monitoring and modoff delay time disabled selected
(parameter SLSx.05 is set to Monitoring and modoff delay time disabled) is described
in the time diagram and table below. For configuration, see section How to configure
SLS function behavior when drive modulation is lost on page 376.
