Shared Supply
A "Main" DC Power Supply can be designed to supply power to the drive's logic as well as to
the Main Power (see Figure 7 and the upper portion of Figure 9). If backup functionality is
required for continuous operation of the drive’s logic in the event of a main power-out, a
backup supply can be connected by implementing “diode coupling” (see the Aux. Backup
Supply in Figure 9).
Note:
Elmo’s Evaluation Board (Catalog number: WHI-EVLBRD-1) implements diode coupling
on the board. When you create your own PCB, you need to implement diode coupling.
