The MACRO link

Description

MACRO is an acronym for Motion and Control Ring Optical, which is a non-proprietary digital interface developed

by Delta Tau Data Systems for connection of multi-axis motion controllers, amplifiers, and I/O on a fiber optic or

twisted pair copper (RJ45 connector) ring. Since the fiber optic cable transmits light and not electricity, it is immune

to electromagnetic noise, capacitive coupling, ground loops, and other wiring problems. In addition, the MACRO

ring allows amplifiers and I/O devices to be connected with a single fiber optic strand, simplifying the wiring and

assembly process.

The fiber optic MACRO Interface enables the PMAC to control multiple servo axes and I/O even when separated by

a great distance. With the MACRO interface, the MACRO system can be up to 3 kilometers (2 miles) from the PMAC

controller or other MACRO devices on the ring. With the RJ-45 electrical interface, the system can be up to 30 meters

(100 feet) away.
