An MMC system consists of a main module (servo analog or SERCOS based) and up to two option modules. An external 24 VDC supply is required to power the MMC’s internal circuitry and external I/O. The 24 VDC is distributed internally to three different buses or sections. When you size your power supply, you must ensure that the supply is large enough to handle the total load and that the maximum current capability of each bus is not exceeded.
In most cases
one power supply can be used for the entire control system. However, depending upon the modules, drives, and external I/O used in your application, you may split the power distribution into two or more power supplies. For example, the Axis I/O on an MMC A2 module can be powered from the MMC, from the drive, or from another external power supply.
