This parameter is used to select the origin (source) of the MainsvoltageOK signal. The signal to be associated with
this function can be selected from the “L_DIGSEL2” selection list.
If the signal is not enabled it means the power supply is not present (MainsvoltagenotOK), whereas if the signal
is enabled it means the power supply is present (MainsvoltageOK).
In the default condition the origin of the Powerlossmainssrc signal is Zero.
The user must connect an external sensor to inform the drive of the mains supply status.
If the function is congured as Powerlossmode=Restart, when the MainsvoltageOK signal is enabled the drive
stops the deceleration ramp and passes to the set reference.
For machines with several drives the external sensor signal must only be connected to the master drive.
