output of the master to the Speed ratio src input (selection list L_VREF) of the slave drives. The master => slave
connection can be achieved via analog signals or fieldbus.
To ensure correct operation of the Powerloss function, the following alarms must be configured as described below:
Since the speed reference and current limit are controlled internally by the Powerloss function, a difference could
occur between the speed reference and motor speed with subsequent activation of the Perd Riferim alarm: to avoid
this, set Par 4552 SpdRefLoss activity = Ignore
During the power failure, the power supply phase loss detection system might not work properly with subsequent
activation of the Phaseloss alarm: to avoid this, set Par 4660 PhLoss activity=Ignore.
