First unit:
50mm2 assuming that the total of servo amplifier
capacities is 27.5kW since 15kW + 7kW + 3.5kW
+ 2.0kW = 27.5kW.

Second unit:
22mm2 assuming that the total of servo amplifier
capacities is 15kW since 7kW + 3.5kW + 2.0kW =
12.5kW.
Third unit:
8mm2 assuming that the total of servo amplifier
capacities is 7kW since 3.5kW + 2.0kW = 5.5kW.
Fourth unit:
2mm2 assuming that the total of servo amplifier
capacities is 2kW since 2.0kW = 2.0kW.
