UMAC-CPCI Turbo CPU Board Hardware Reference Manual
Introduction 1
INTRODUCTION
Delta Tau’s UMAC-CPCI sy stems provide a compact and clean integration of motion and I/O control for
sophisticated automation equipment. The system consists of a modular set of 3U-size (100mm x 160mm)
boards in the “Compact PCI” format, implementing Turbo PMAC software and hardware functions,
communicating with each other over a common backplane (the “Compact UBUS”). All field wiring is
available on rear connectors, suitable for a user-designed distribution system to the machine. UMAC
(Universal Motion and Automation Controller) -CPCI systems provide integrated connectivity as well as
ease of assembly, diagnostics, and repair. UMAC-CP CI systems differ from “standard” UMAC systems
in that all field wiring comes to the back of the rack, behind the backplane, instead of direct top and
bottom access.
The UMAC-CPCI Turbo CPU board (Part number 3A0-603625-10x) implements a Turbo PMAC2 CPU
in the 3U CPCI form factor. Its software operation is completely identical to other Turbo PMAC2
controllers.
Note that a Compact PCI interface does not automatically come with a UMAC-CPCI system, nor is one
necessary to communicate to the system, given the other possible communications ports: RS-232, RS-
422, USB, and Ethernet.
This picture shows the UMAC-CPCI Turbo CPU
board. The connectors on the right side plug into the
“Compact UBUS” backplane board, with the bottom
right connector being the bus connector, and the top
right connector containing the external “field wiring”
signals, which typically pass through the backplane
board. The connector at lower left is an RS-232 port
intended for setup and diagnostics; the stack
connectors top and bottom provide the link to a CPCI
“bridge board”.
This picture shows a sample configuration of a
UMAC-CPCI system, not installed in its rack. It
consists of the following components:
1. Rack power supply (not a Delta Tau product)
2. UMAC-CPCI CPU board
3. ACC-11C Sinking I/O board
4. ACC-24C2A analog axis interface board
5. ACC-C8 8-slot Compact UBUS backplane.
Note the “pass-through” connector on the
back for field-wiring distribution. In this
picture, alternate slots in the backplane have
been left open to make each board more
visible. This does not have to be done in
actual use.
