"Main"
versus "Expansion" Boards (XMP-analog only)
XMP-analog
controllers may be configured for varying numbers of axes. Up
to 8 axes are controlled by a single "main" controller
board. Where more than 8 axes are required, it is necessary to
add an "expansion" board.
Expansion
boards consist of separate electronics, very similar in appearance
and function to main boards. Typically, an expansion board is
located on the bus or backplane immediately adjacent to a main
board. Both boards (main and expansion) are connected via a short
ribbon cable. When connected together, one main and one expansion
board constitute a single, unified "controller."
Expansion
boards are not available for XMP-SERCOS controllers.
