about icons

The company headquarters is based in Tewkesbury, Gloucestershire, which also comprises its primary research and development hub. Additional R&D facilities are located in Italy, Bulgaria,and China. Application development teams are located in the UK, USA, Italy, India and China, and a global sales network comprises over 100 partners.

In 2017 Trio was acquired by the Estun Group, which is supporting Trio in its growth with assistance through shared facilities and R&D as well as financial backing. Trio has exceeded 15% growth year on year since the acquisition. In addition to the primary global markets, a significant proportion of Trio’s business is in China where the company’s motion control capability has enabled Estun to become a major player in the China automation market. Despite the presence of the Estun brand, motion control products in China carry Trio branding.

Launch of the DX4 is symbolic of the collaboration between Trio’s engineers and the wider Estun Group. Lead by Trio’s domain expertise in motion control, the launch has delivered a jointly developed servo system, specifically optimised for superior performance in motion applications


Our Products

Trio Motion Technology has been manufacturing high-quality motion controllers branded Motion Coordinators since 1987 and has a comprehensive range that allows economical, flexible and seamless control of 1 to 128 axes of servo motors, stepper motors, piezo motors or hydraulic systems. Trio products can be found in virtually every servo and stepper application.

Our Approach

We believe in supporting rather than competing with our distributors and believe that the better the knowledge of the customer the better the end result. We train all of our distributors before they sell our products and we offer a comprehensive training program for customers.


Our manufacturing is done by carefully selected subcontractors, allowing us to quickly ramp up production to fulfil large orders as they happen. Trio purchases all the component parts and provides kits to the subcontractors for manufacturing, allowing us to control the quality of the components used. We aim to deliver most orders from stock.


With offices in Tewkesbury (UK), Pittsburgh (USA), Pune (India), Shanghai (China) and Milan (Italy), Trio Motion Technology supplies its' entire product range worldwide via a network of fully supported distributors.

We offer the very best technical support in the industry, and our customers regard our application and technical support capability very highly.

ISO 9001

The ISO 9000 family addresses various aspects of quality management and contains some of ISO’s best known standards. The standards provide guidance and tools for companies and organizations who want to ensure that their products and services consistently meet customer’s requirements, and that quality is consistently improved.

Existing in its present form since 1985, the CE marking indicates that the manufacturer or importer claims compliance with the relevant EU legislation applicable to a product, regardless of where manufactured. By affixing the CE marking on a product, a manufacturer is declaring, at its sole responsibility, conformity with all of the legal requirements to achieve CE marking which allows free movement and sale of the product throughout the European Economic Area.


These are marks consumers rarely see because they are specifically used on component parts that are part of a larger product or system. These components may have restrictions on their performance or may be incomplete in construction. The Component Recognition marking is found on a wide range of products, including some switches, power supplies, printed wiring boards, some kinds of industrial control equipment and thousands of other products. Products intended for Canada carry the Recognized Component mark "C."

Learn only one programming environment

A single programming interface for motion and machine control up to 64 axes of coordinated motion, Motion Perfect is designed to make setup, diagnostics, commissioning and using our range of Motion Coordinators as simple as possible. Program in IEC 61131-3 and Motion-iX languages to best fit your application. Motion Perfect provides the user with an easy to understand Windows based interface for rapid application development, controller configuration and monitoring of controller processes. The integrated UNIPLAY system makes HMI screen development quick and easy.

Easy programming of complex motion

The Motion-iX programming language is a powerful suite of instructions and tools developed over 24 years It makes even the most advanced motion programming easy and provides ease of programming for many complex applications. With multitasking and subroutine capabilities, it allows users to create modular programs, ideal for code reuse and better readability thus saving valuable time.
The syntax is similar to that of other structured BASIC systems. Functions include:

  • Linear, Circular, Helical and spherical interpolation
  • Variable speed / acceleration profiles
  • Electronic gearboxes
  • Electronic cam profiles generate motion based on the position of another axis or based on time
  • Superimpose multiple moves / cams to generate the final motion
  • High Speed Registration; ideal for adding motion into continuous processes
  • Communication functions enabling interface to HMI or SCADA type systems
  • All of our programming and utility software is FREE with no support charges or licence fees

why buy trio

Modular architecture saves costs

A range of Motion Coordinators, with unique modular design to make sure that whatever the drive, motor and feedback type you choose, you can control it simply, with only the hardware needed. Then only pay for the features that you use on the controller, saving cost and reducing the panel space required.

Protect your investment with program encryption

Protect your software inside the controller, allowing you to maintain any in house intellectual property and stay ahead of your competition.

The Project Encryptor is a utility that enables a programmer's intellectual property to be licenced to individual Motion Coordinators. A project is developed normally using Motion Perfect and then encrypted. Once encrypted the program is safe to distribute and can only be loaded to a controller with a correct key, which is unique to both the controller serial number and source project.

  • Licence your intellectual property
  • Greater security for machine exporters
  • Allows diagnostic access for maintenance purposes and program upgrades in the field whilst protecting IP

Your choice of programming methods

We think that Motion-iX will solve all your programming needs, however, if you have learnt another standard programming language we support G Code and IEC 61131 programming methods. Your choice!

G Code is widely output from CADCAM systems for CNC machines. Our system interprets standard G and M codes through an interpreter. This gives you the flexibility to change the support for custom G or M codes.

The built in industry standard IEC 61131 runtime, is an easy to use full function PLC programming system.

Integrated into the target Motion Coordinator the runtime kernel allows multiple PLC tasks to be run and has access to all I/O and distributed I/O. The IEC 61131 program has access to all Trio motion commands, axis parameters, VR and Table memory.
