The APT™ MST602 module is a dual-channel, high-resolution, rack-mounted stepper motor driver designed for use with the APT MMR601 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 APT MMR601 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.

USB connectivity via the MMR601 Rack Enclosure provides easy plug and play PC operation. Multiple modules can be connected to a single PC via standard USB hub technology for multi-axis motion control applications. Coupling this with the very user friendly APT software allows the user to get up and running very quickly. For example, all relevant operating parameters are set automatically for Thorlabs' stage/actuator products. Advanced custom motion control applications and sequences are also possible using the extensive ActiveX® programming environment, which is described in more detail on the Motion Control Software and APT Tutorials tabs.

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.

Thorlabs offers two platforms to drive our wide range of motion controllers: our Kinesis® software package or the legacy APT™ (Advanced Positioning Technology) software package. Either package can be used to control devices in the Kinesis family, which covers a wide range of motion controllers ranging from small, low-powered, single-channel drivers (such as the K-Cubes™ and T-Cubes™) to high-power, multi-channel, modular 19" rack nanopositioning systems (the APT 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. A Central Sequence Manager supports integration and synchronization of all Thorlabs motion control hardware.

Our legacy APT System Software platform offers ActiveX-based controls which can be used by 3rd party developers working on C#, Visual Basic, LabVIEW™, or any Active-X compatible languages to create custom applications and includes a simulator mode to assist in developing custom applications without requiring hardware.

By providing these common software platforms, Thorlabs has ensured that users can easily mix and match any of the Kinesis and APT controllers 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 packages allow 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.

A range of video tutorials is available to help explain our APT system software. These tutorials provide an overview of the software and the APT Config utility. Additionally, a tutorial video is available to explain how to select simulator mode within the software, which allows the user to experiment with the software without a controller connected. Please select the APT Tutorials tab above to view these videos, which are also available on the software CD included with the controllers.

These videos illustrate some of the basics of using the APT System Software from both a non-programming and a programming point of view. There are videos that illustrate usage of the supplied APT utilities that allow immediate control of the APT controllers out of the box. There are also a number of videos that explain the basics of programming custom software applications using Visual Basic, LabView and Visual C++. Watch the videos now to see what we mean.

Hi. I’m utilising LabVIEW to control the following items, 3 x MST602, installed into a MMR601, along with a MAX604/M 6-Axis stage. Currently, I don’t have the physical hardware available, hence I’ve configured the Kinesis simulator with two BSC103 3 Channel Motor Controllers, these controllers in themselves are marked as ‘obsolete’, but they are the nearest I can find, in relation to the MST602 APT Stepper Motor Control Modules. Anyway, moving on from this issue with the Kinesis simulator product selection, I can get the Kinesis User GUI software to satisfactory communicate with the Kinesis simulator. However, when I configure LabVIEW to utilise the Kinesis software provided .dll to implement .NET control ‘calls’, I get a reported error of “No Suitable Devices Found”, consequently checking the Kinesis simulator, there isn’t any connection activity, which you do see, when the Kinesis User GUI software connects to the Kinesis simulator. So I’ve found a similar issue on the NI forum (https://knowledge.ni.com/KnowledgeArticleDetails?id=kA00Z0000019RKySAM) , and have made the users suggested changes, but to no avail. So my query is, as I’m wanting to use the Kinesis simulator, and not the actual hardware platform, do I have to invoke a connection to the simulator first, prior to attempting to establish a connection from “BenchtopStepperControl.NET”? I note that there is a SimulationManager (within “Thorlabs.MotionControl.DeviceManagerCLI.dll”), but it doesn’t contain any public constructors, so it doesn’t appear that I can access the Kinesis simulator in that way. So if you could kindly provide me with a detail explanation of the procedure, or an example of LabVIEW code that would facilitate the utilisation of the Kinesis simulator, I would be most grateful. Thanks and Kind Regards. – Les.

Response from Ben at Thorlabs: Thank you for your feedback. I see you've also emailed us & I've got back to you with a solution on connecting to this hardware. The methods for use of the Simulator can be found within the Kinesis .NET help file > DeviceManagerCLI.dll. Within the Simulator, when selecting the BSC* series you can select Hardware Type revision which will enable you to simulate the latest hardware types. The Modular Stepper Controller is a Stepper Controller based on the Benchtop Stepper Motor (BSC103, BSC102, BSC101, BSC203, BSC202, BSC201) device used in the Modular Rack (MMR601). The Stepper Controller uses the Benchtop Stepper Motor (BSC103, BSC102, BSC101, BSC203, BSC202, BSC201) modules for it's functionality.

Dear Sir/Madam, Could you send me an older version of the APT software so that I can install it in my Windows XP system? Thanks! Best regards, Guozhen
msoulby  (posted 2015-03-31 06:27:59.0)
Response from Mike at Thorlabs: We stopped supporting windows XP for our APT software since 2013; all of our latest versions will only operate on windows 7 operating systems or later. However I have contacted you directly with details on how to download the very last version of APT that is compatible with Windows XP.
user  (posted 2014-05-14 16:01:59.73)
Are you only support Windows platforms? And than only via ActiveX? Please make a simple dll (.so) shared libary next time.
msoulby  (posted 2014-05-14 11:08:42.0)
Response from Mike at Thorlabs: Currently our APT package is only supported on windows based operating systems, back to windows XP. If you are using a non-windows platform then you will need to use our low level communications protocol over a virtual serial port to communicate with the controller, this document can be view at the following link http://www.thorlabs.de/software/apt/APT_Communications_Protocol_Rev_11.pdf We also have an APT.dll available which does not use ActiveX; if you can provide us with an email address we would be happy to send you this .dll and some details on its use.

Hello, do the auto alignment features of the MMR601/MNA601/R work equally well (at all?) with the MST602 stepper modules. I need the extra travel/flexibility of stepper motor/drives. Thanks, Jonathan
msoulby  (posted 2014-02-05 04:29:12.0)
Response from Mike at Thorlabs: The MNA601 can only provide piezo motion in response to the feedback signal. This signal can either be optical from the OPTICAL/PIN IN photodiode or an analogue electrical signal 0-10V input on the SIG IN connector. The MNA601 is only able to scan and track within the range of piezo travel provided by the stage you are driving. The stepper motors are there to provide coarse adjustments to get the stage close enough so that the piezo actuators can refine the alignment. If you need to use the stepper motors to initially find the signal then a dark search raster scan can be developed in a program such as LabView or Matlab to find the coarse position. Once this is position is found you can switch the program to the piezos and Nanotrak to optimise and maintain this alignment.

Response from Tim at Thorlabs to Michal: Thank you for your inquiry. All of the Thorlabs Rack System Modules require the use of the MMR601 for operation.

Response from Javier at Thorlabs to i.abbadi: Thank you for your reply.It looks like you can use the SetAbsMovPos and MoveAbsolute commands. I was not able to contact you directly via e-mail regarding your last inquiry. Please contact us at techsupport@thorlabs.com so that we can discuss your application.

hi , thanks for your response , well i want to command the rotation of two motors at the same time ;im looking for the instruction how to set its position without turning or make a boolean command to move the motors after setting there positions before , im using a BSC102 and the motors are connected to its channels
jjurado  (posted 2011-05-26 10:12:00.0)
Response from Javier at Thorlabs to i.abbadi: Thank you very much for contacting us. The LLSetGetDigOPs method sets or gets the status of the digital outputs on the APT unit associated with the ActiveX control instance. If the bSet parameter is set to TRUE, the method sets the output state. If bSet is set to FALSE, the method returns the output state. I will contact you with more details about this method and I will also like to get additional info about your application. You can also find more information in the Help section of the APT software: Start > All Programs > Thorlabs > APT > Help > APT Server Help > Programming Guide.
i.abbadi  (posted 2011-05-26 06:54:14.0)
hi,we have the MST601 and we could not control it by Labview. can we have more information about the LLSetGetDigOPs commands?
Thorlabs  (posted 2010-10-20 16:15:29.0)
Response from Javier at Thorlabs to jouko.viitanen: the User I/O connections of the MST601 are intended for use with ActiveX compatible platforms such as Visual Basic, LabVIEW, etc. You would use the low level commands LLSetGetDigOPs and LLSetGetHostDigOPs, which talk to the motherboard I/O instead of the separate card I/Os. I will contact you directly with more information about these commands.
jouko.viitanen  (posted 2010-10-19 12:54:47.0)
We have your MST601 stepper motor controller in the MMR rack. The controller works ok. I would also like to use the the 4 digital output bits available from the "User I/O" connector of the MST601. However, they are not available from the GUI panel, and I did not find any hints from the APT configurator utility, if some other driver needs to be installed in order to be able to switch the bits on/off in the APT user interface.
