306 Parameters
SLSx.05 SLS ramp modoff
reaction
Selects the fault reaction in case the drive
modulation is lost during the SLS
deceleration ramp, when SLS is activated
from speed which is higher than SLS limit
speed. Modoff
delay time
Modoff delay time If drive modulation is lost during the SLS
deceleration ramp and the modulation does
not return within SLSx.06 time, FSO
activates STO.
Note: If speed is below SLS limit (eg,
200.22), modoff is ignored.
Monitoring active If drive modulation is lost during the SLS
deceleration ramp, SLS ramp or time
monitoring (SLSx.03) is kept on. Limit hit is
generated based on the last valid speed
estimate information of FSO.
Monitoring active
and modoff delay
time
Both Modoff delay time and Monitoring
active values are in use: FSO generates the
hit based on whichever condition is met first
and activates the STO.
Monitoring and
modoff delay time
are disabled
If drive modulation is lost during the SLS
deceleration ramp, FSO does not activate
STO. SLS indication (eg, SLSx.15) goes on
after STO.14 time has elapsed.
SLSx.06 SLS ramp modoff
delay time
Time to trip when modulation is lost.
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.
