AFE Control Application
A simple application that controls external precharge relays and contactors, and ensures that all pre-requisites for regenerative operation of the
drive are satisfied. If the drive is used as an active front end this application MUST be loaded and enabled. If the shown control wiring to the
control card terminals is correct no further modification to the application is needed to be able to run in AFE mode. (The line sync card needs to
be wired to the encoder option too.)
