The Turbo PMAC2 UMAC CPU is intended to be used in a Compact UMAC Rack (CPCI), which is a modular rack format permitting the user to configure his or her rack with I/O cards, servo control cards, or any other accessory card Delta Tau offers for the UMAC Rack format, to build a totally user-customized system. The Turbo PMAC2 UMAC CPU can control up to 32 axes, whether through direct local control. There is presently no MACRO accessory or option for this controller.
