4.2.4 Combi AC configuration (traction + pump)

When the inverter is configured as COMBIACE2 NEW GENERATION for
controlling one traction motor and one pump motor, the pinout differs from that of
the dual traction configuration only for the pins listed in the following table. The
other ones are unchanged both in name and in function (see paragraph 4.2.3).
