Size the DC Bus cables for remote Drive-Motors, aka Motor Integrated Drives (MiDs), located around the machine, connected by suitable cables in a daisy chain arrangement.
Cables can be selected in the Cable DC Bus form, launched from the Main form as shown.
This example shows Power Group 1, mounted in a cabinet, with an Auxiliary Power Module (APM) in Slot 2, stepping down the DC Bus from 540Vdc to 58Vdc to feed Power Group 2.
The cable length is an important factor in sizing the cables, as the total cable length of the daisy chain can result in signficant voltagen dips further down the chain. Additional loads such as remote I/O and/or the motor holding brake can be added.
