I/O Board for the Atom Servo Drive Modules, AXXAYYYVPX-I

ESI Motion’s servo drive systems are designed for precision military, aviation, automotive, robotics, and specialized industrial applications where size and weight are critical. ESI Motion’s Proton & Atom incorporates field proven rugged controller and high efficiency wide-bandgap semiconductor-based power driver modules and offers multiple configurations. It is designed and manufactured in ESI Motion’s USA facility and complies with a wide range of military and industry standards. Options include a selection of input voltages, output current amplitudes, and feedback devices. It comes with an industry benchmark user interface allowing the most flexible and precise system integration and control.

The Proton & Atom I/O Boards are an optional circuit board that can be purchased along with the Proton or Atom Servo Modules.

Key Features

The I/O Board provides the user with a platform that can be used for system development, prior to the design of a user-defined board that will mate with the Atom Servo Drive Module.

The I/O Board provides all the connections necessary for motor control. Signals are arranged by connector into three groups:
J3 Motor A Feedback, J4 System, and J6 Motor B Feedback. Voltages are: VBUS Input Power on J8, 28VDC IN on J4, and Motor A & B Power Outputs on J2 and J5, respectively.

Refer to Atom Datasheet for the electrical characteristics of signals and voltages.

A 5V regulator on the I/O Board is used to power both the Atom Servo Module controller (VLOGIC) and external motor feedback devices (up to 0.5A). The I/O Board is designed to work with Main Power (VDC_IN) from 10V to 90V.
