MACRO CONNECTIVITY
Introduction to MACRO
MACRO
MACRO stands for Motion and Control Ring Optical. It is a high bandwidth non-proprietary digital
interface industrialized by Delta Tau Data Systems for distributed multi-axis systems.
MACRO can be connected using either fiber optic or twisted copper pair RJ45 cables. The RJ45
electrical interface can extend to up to 30 meters (or about 100 feet), and the fiber optic interface can
extend to up to 3 kilometers (or about 2 miles). The following are some of the many advantages
which MACRO offers:
Noise Immunity: MACRO transfers data using light rather than electricity which renders it
immune to electromagnetic noise and capacitive coupling.

Wiring Simplicity: Single-plug connection between controllers, amplifiers, and I/O modules
minimizing wiring complexity in large systems.

High Speed: data transfer rate at 125 Megabits per second, and servo update rates as high as
65 KHz.

Centralized, Synchronized Control: No software intervention is required on the MACRO
stations. One or multiple rings can be controlled, synchronized, and accessed using a single
ring controller.

The following diagram depicts the general formation of a simple MACRO ring.

Note
It is possible to have multiple/redundant rings and master/controllers
in one system. For simplicity, we will limit the discussion in the
following section(s) to the basic setting parameters of a single
MACRO ring and controller. Also, we will address the stations as
slaves and the ring controller as master.
