How can the driver ATV71 differentiate if it's supplied by a single or three phase supply?

In case the drive is supplied by a 3 phase voltage supply, set the parameter ( IPL  - Ignore ) to " No ". This parameter represents the input phase loss and can be found in the " Simply start " menu ( Sim ) or the " Fault Management " menu (  Flt ).

In case of supplying the drive with a single phase source, set this parameter to " Yes " , this means that the drive will ignore any phase loss.
