Active Front End (AFE) is a mode of operation of the drive required for full 4-Q regeneration capabilities. AFE control mode allows a single
AC30P/AC30D drive to act as a 4-Q power supply unit that is capable of drawing (motoring) and supplying (regenerating) sinusoidal, near-unity
power factor current from the supply. The output from the 4-Q Regen drive acts as a DC supply which is used to power other drives on a common
DC Bus system.
AFE Control Mode is available as a standard option in the AC30P/AC30D firmware, however set-up and installation requirements need to be
adhered to in order to use a drive as 4-Q regen unit. These requirements are described in more detail in the paragraphs that follow.
Hardware Requirements
The figure below shows the typical installation configuration of the drive operating in AFE control mode.
