MACRO-CPU Hardware Reference

INTRODUCTION

The 3U MACRO-CPU board is the processor and MACRO interface board that is used in a 3U MACRO Station

(in either UMAC MACRO or MACRO Stack configuration).

Note

There are 3 documents that describe the operation of Delta Tau Data Systems Inc. 3U MACRO

Station products:

•

UMAC System Manual (General Product Overview)

3U MACRO Station User’s Manual

3U MACRO Station Software Reference

This manual describes the interfaces and physical hardware that is used on the

3U MACRO CPU.

The UMAC MACRO and the MACRO Stack provide a remote interface for encoders, flags, direct-PWM digital

drives, analog drives, stepper drives, analog I/O, and digital I/O for Delta Tau Data's PMAC products that have a

MACRO interface.

The UMAC MACRO and MACRO Stack configurations communicate with PMAC2 Ultralites or Turbo PMAC2

Ultralites solely through the MACRO ring, interfacing to standard drives, encoders, flags, and I/O through on-

board connectors. This MACRO Station integrated packaging and connectivity strategy provides revolutionary

flexibility and ease of use.

A 3U MACRO Station consists of a set of “3U” format Euro-cards (100 x 160 mm) that can be assembled in a

variety of configurations. When used in the rack configuration, connected through a backplane bus, the backplane

is UBUS format, designed by Delta Tau Data Systems Inc. for motion control and I/O interfaces.

When using the fiber optic MACRO interface, the 3U MACRO Station can be up to 3 kilometers (2 miles) away

from the PMAC2 controller or any other station on the ring. When using the RJ-45 copper electrical interface, it

can be up to 100 meters (~330 feet) away.

The 3U MACRO Station allows PMAC2 MACRO controllers to control servo axes and I/O just as if they were

directly connected to the PMAC2, even though they may be a great distance away. The only interface needed

from the PMAC2 is the electrically isolated MACRO ring.

Typically, a PMAC2 “Ultralite” board, one without any of its own servo interface circuitry, is used with the

MACRO Station to provide the most cost-effective solution.
