4.6.3 Power supply "Single + Dual"
The supply voltage for the axis controllers is supplied by the supply unit ServoOne CM-P
via the busbars (DC link). This voltage, also called the DC link voltage, is between
565V DC and 678 V DC, depending on the mains supply to the SO CM-P (400 V AC
and 480V AC).
The expansion module is used to protect, monitor and adapt the smaller cable cross-
section (DC link = lower current carrying capacity) of the axis controllers SO CM BG1+2
to the larger cable cross-section (DC link = higher current carrying capacity) of the axis
controllers SO CM BG3+4.
