24.20 4550SpdRefLossthreshold rpm INT16 100 0 CALCI RW FVS
Setting of the threshold below which the speed reference loss alarm SpdRefLoss occurs.

24.21 4552SpdRefLossactivity ENUM Ignore 0 4 RW FVS
Setting of the behaviour of the drive in case of a speed reference loss alarm SpdRefLoss. This alarm indicates
that the difference between the speed regulator reference and the actual motor speed is more than 100 rpm.
This alarm must be disabled (= 0 Ignore) when parameter 556 Controlmodeselect is set to Torque (0) or
when parameter 2354 is set to a value other than zero.

24.22 4554SpdRefLossholdoff ms UINT16 1000 0 10000 RW FV_
Setting of the delay between the signalling of the speed reference loss alarm condition SpdRefLoss and ena-
bling of the alarm. If an alarm condition occurs, the drive will wait for the set time before enabling the alarm. If
the alarm is removed within the set time, the drive will not indicate any alarm condition.

24.24 4562SpdFbkLossholdoff ms UINT16 200 0 10000 RW FVS
Setting of the delay between the signalling of the speed feedback loss alarm condition SpdFbkLoss and the
enabling of the alarm. If an alarm condition occurs, the drive will wait for the set time before enabling the alarm.
If the alarm is removed within the set time, the drive will not indicate any alarm condition.

24.25 4564SpdFbkLossthreshold rpm INT16 100 5 CALCI RW FVS
For SE (single ended) encoders and with parameters 2110 or 5110 = (3) Control A-B-SE.
The Speedfbkloss[22] alarm control is enabled when the speed reference is higher than the value set in this
parameter
If using incremental digital encoders in single-ended mode, this parameter sets the limit above which the drive
executes the action set with parameter 4560 SpdFbkLossactivity.

24.26 4570Driveovldactivity ENUM Ignore 0 4 ERW FVS
Setting of the behaviour of the drive in case of a drive overload alarm Driveovld. This alarm indicates that the
drive overload threshold has been reached.
