4.7.6. 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 8 and the upper portion of Figure 10). 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 10).
