3.8.3. 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 6). If backup functionality is required (for storing control parameters in
case of power-outs) an additional backup supply can be connected by implementing 'diode
coupling' (see the Aux. Backup Supply in Figure 8: Shared Supply Connection Diagram
).
Note: When using Elmo’s Evaluation Board (Catalog number: WHI-EVLBRD-1), the diode coupling
is “built in”. When you create your own PCB, you need to implement diode coupling.
