The MST602 module is a dual-channel, high-resolution, rack-mounted stepper motor driver designed for use with the MMR601 or MMR602 Motion Control 19" Modular Rack System. It has been designed to drive 2-phase bi-polar stepper motors up to 50 W, with or without encoder feedback, and is compatible with the full range of stepper-motor-equipped nanopositioning actuators and stages offered by Thorlabs. Alternatively, it is also compatible with any generic two-phase bi-polar motor of varying powers and varying cardinal step sizes.
This stepper motor controller has been designed specifically to operate with the highly flexible MMR601 or MMR602 Motion Control 19" Modular Rack System. Up to 6 MST602 stepper modules can be fitted to a given rack system, providing a scalable motion control solution for multi-axis motion control applications. For stand-alone controller options, please see the table below.
When used with a MMR601 or MMR602 Rack enclosure, this unit can be used with a PC via USB connection. Multiple modules can be connected to a single PC via standard USB hub technology for multi-axis motion control applications. Coupling this with the user-friendly Kinesis software allows the user to get up and running very quickly. Advanced custom motion control applications and sequences are also possible using the extensive Kinesis programming environment, which is described in more detail in the Kinesis Software tab.
An optional 2-axis joystick console (item # MJC001) is also available for tactile, manual positioning of a stage. See the manual, found by clicking on the red Docs icon (
), for more information on using the joystick console.
Cabling
Cables for connecting actuators or stages to the controller are shipped with the actuators or stages, not the controller. If you need help identifying the appropriate replacement cable, please contact Tech Support.

KINESIS SOFTWARE
Software
Kinesis Version 1.14.50
The Kinesis Software Package, which includes a GUI for control of Thorlabs' Kinesis system controllers.
Also Available:
- Communications Protocol
Kinesis GUI Screen
Thorlabs offers the Kinesis® software package to drive our wide range of motion controllers. The software can be used to control devices in the Kinesis family, which covers a wide variety of motion controllers ranging from small, low-powered, single-channel drivers (such as the K-Cubes™) to high-power, multi-channel benchtop units and modular 19" rack nanopositioning systems (the MMR60x Rack System).
The Kinesis Software features .NET controls which can be used by 3rd party developers working in the latest C#, Visual Basic, LabVIEW™, or any .NET compatible languages to create custom applications. Low-level DLL libraries are included for applications not expected to use the .NET framework and APIs are included with each install. A Central Sequence Manager supports integration and synchronization of all Thorlabs motion control hardware.
By providing this common software platform, Thorlabs has ensured that users can mix and match any of our motion control devices in a single application, while only having to learn a single set of software tools. In this way, it is perfectly feasible to combine any of the controllers from single-axis to multi-axis systems and control all from a single, PC-based unified software interface.
The software package allows two methods of usage: graphical user interface (GUI) utilities for direct interaction with and control of the controllers 'out of the box', and a set of programming interfaces that allow custom-integrated positioning and alignment solutions to be easily programmed in the development language of choice.
