Shared Supply for up to 100 V Models
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 8). 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 Auxiliary Backup Supply in Figure 10).
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.
