Expansions and Add-ons
Some XMP controllers may be enhanced with additional
hardware. These include:
These expand the number of axes run by a controller by adding up to two
motion blocks for a total of 16 axes. Unlike main boards, expansion boards
do not contain SHARC DSP processors. They are available for XMP-PCI and
XMP-CPCI-6U form factors only (not available for XMP-CPCI-3U and XMP-SERCOS-PMC
controllers). An expanded XMP-CPCI-6U controller is shown below.
Scale Interpolation Modules (SIMs) are mounted mezzanine-style to motion
controllers that use encoders with sinusoidal outputs. These enhance positional
resolution significantly and are available for XMP-PCI and XMP-CPCI-6U
controllers only. A maximum of two SIM4 modules may be added to each main
or expansion board. A SIM4 module is shown below with an XMP-PCI controller.
