This message displays the Winding 1 (2/3) phase A current demand.
This message displays the Winding 1 (2/3) phase B current demand.
This message displays the Winding 1 (2/3) phase C current demand.
This message displays the maximum Winding 1 (2/3) current demand and
the phase in which it occurred since the demand data was last reset.
This message displays the date when the maximum Winding 1 (2/3) current
demand was detected. If the date has never been programmed, this
