Thorlabs' K-Cube™ Strain Gauge Reader is a part of Thorlabs' new and growing Kinesis® line of high-end, compact motion controllers. It is designed to measure, condition (rectify and filter), and display the feedback signal derived from AC bridge strain gauge systems. The KSG101 provides immediate 'out of the box' operation with the complete Thorlabs range of strain-gauge-equipped bare piezo stacks, actuators, stages, and force sensors.

This K-Cube unit can be used for position, force, or voltage strain-gauge reading. When used in isolation, it can measure the deflection/extension in a strain gauge with nanometer level resolution. Alternatively, it can be used with Thorlabs' force sensor products (Item #s FSC102 and FSC103) for high-sensitivity force sensing down to mN levels. Closed loop positioning can be achieved by using the KSG101 and KPZ101 together with the CA2906 SMA to SMA cable, which is not supplied with the KSG101 but is available separately. The strain gauge reader is also equipped with a low-voltage monitor output (0-10 V) that is proportional to the strain gauge extension, thus providing a conditioned feedback/monitoring signal for third party systems.

Embedded software allows this unit to be fully operated using the on-unit menu button, OLED display, and control wheel or using external trigger signals. The unit can switch between position, force, and voltage (feedback signal) readout displays; control force sensors; be used with our USB controller hubs; and be calibrated without being connected to a PC. In addition to these on-unit controls, USB connectivity provides simple PC-controlled operation with two available software platforms: our new Kinesis software package or our legacy APT™ (Advanced Positioning Technology) software package.

The Kinesis Software features .NET controls which can be used by 3rd party developers working in the latest C#, C++, Matlab, LabWindows/CVI, Visual Basic, LabVIEW™, or any .NET compatible languages to create custom applications. Our legacy APT software allows the user to quickly set up complex move sequences with advanced controls made possible via the ActiveX® programming environment. For example, all relevant operating parameters are set automatically by the software for Thorlabs stage and actuator products. For more details on both software packages, please see the Motion Control Software, Kinesis Tutorials, and APT Tutorials tabs.

The unit has a highly compact 60.0 mm x 60.0 mm x 49.2 mm footprint, allowing it to be positioned close to the system for added convenience when using the top panel controls. Tabletop operation also allows minimal drive cable lengths for easier cable management. Each unit contains a front-located power switch that, when turned off, saves all user-adjustable settings. Please note that this switch should always be used to power down the unit. For convenience, a 1.5 m long Type A to Type Micro B USB 3.0 cable is included with the KSG101 cube.

Optical Table Mounting Plate
Each unit comes with a mounting plate that clips onto the base of the module. The plate contains two magnets for temporary placement on an optical table and two counterbores for 1/4"-20 (M6) cap screws for a more permanent placement on the tabletop. Please see the Specs for a mechanical drawing of the table mounting plate and the Mounting Options tab for how to mount the plate.

Power Supply Options
The KSG101 K-Cube, which does not ship with a power supply, can be powered using a TPS002 power supply. The TPS002 power supply plugs into a standard wall outlet and provides +15 VDC, -15 VDC, and +5 VDC for up to two K- or T-Cubes.

The KSG101 is also compatible with the KCH301 and KCH601 USB Controller Hubs, available below. Our USB Controller Hubs have a single USB connection that provides USB connectivity to all the K-Cubes and T-Cubes connected to the hub. It is especially useful when the KSG101 is used with the KPZ101 Piezo Controller since it allows for direct communication between the cubes connected on it.

K-Cube Mounting Options

Two options are available to securely mount our K-Cube controllers onto an optical table. An optical table mounting plate, provided with every K-Cube, allows for a single controller to be attached to an optical table. Alternatively, three- and six-port USB controller hubs are offered (sold separately) that can mount and power our K-Cube controllers. These options are described in further detail below.

Optical Table Mounting Plate
Each K-Cube unit comes with a mounting plate that clips onto the base of the controller, as shown in the animation below. The plate contains two magnets for temporary placement on an optical table and two counterbores for 1/4"-20 (M6) cap screws for a more permanent placement on the tabletop. Please see the Specs tab for a mechanical drawing of the table mounting plate.

Kinesis USB Controller Hubs
Multiple units can be mounted and connected to a single PC by using the KCH301 or KCH601 USB Controller Hubs. They each consist of two parts: the hub, which can support up to three (KCH301) or six (KCH601) K-Cubes or T-Cubes, and a power supply that plugs into a standard wall outlet. K-Cubes simply clip into place using the provided on-unit clips, while current- and previous-generation T-Cubes require the KAP101 Adapter Plate, shown in the animation below. The hub vastly reduces the number of USB and power cables required when operating multiple controllers.

K-Cube Table Mounting Plate


Unlike T-Cubes, every K-Cube includes a mounting plate that clips onto the base of the controller. The plate contains two magnets for temporary placement on an optical table and two counterbores for 1/4"-20 (M6) cap screws for more permanent placement on the tabletop.

Kinesis USB Controller Hubs


3- and 6-Port USB Controller Hubs allow multiple controllers to be connected to one PC for multi-axis applications. K-Cubes can be directly attached to the hubs while T-Cubes require a KAP101 Adapter Plate.

Introducing Thorlabs' Kinesis® Motion Controllers

A major upgrade to the former-generation T-Cubes, the growing K-Cube line of high-end controllers provides increased versatility not only through the new Kinesis software, but through an overhaul and updating of their physical design and firmware.

Every K-Cube controller includes a digital display. In addition to basic input and output readouts, this display hosts a number of menu options that include zeroing, force sensor select, and unit select. The on-unit wheel and menu button are used to scroll through the available options. Each unit contains a front-located power switch that, when turned off, saves all user-adjustable settings as well as two bidirectional SMA trigger ports that accept or output a 5 V TTL logic signal.

Please see the table to the right for a full comparison of the features offered by our new KSG101 K-Cube and previous-generation TSG001 T-Cube strain gauge controllers.

Kinesis USB Controller Hubs
Complementing our K-Cubes are our Kinesis USB 2.0 controller hubs. With two versions available for three or six K- or T-Cubes, these USB hubs are designed specifically for communication between multiple controllers and the host control PC. These hubs are backward compatible with our T-Cubes.

K-Cubes simply clip into place using the provided on-unit clips, while current- and previous-generation T-Cubes require the KAP101 Adapter Plate, shown in the animation to the below right. The hub vastly reduces the number of USB and power cables required when operating multiple controllers.

K-Cube Table Mounting Plate


Unlike T-Cubes, every K-Cube includes a mounting plate that clips onto the base of the controller. The plate contains two magnets for temporary placement on an optical table and two counterbores for 1/4"-20 (M6) cap screws for more permanent placement on the tabletop.

Kinesis USB Controller Hubs


3- and 6-Port USB Controller Hubs allow multiple controllers to be connected to one PC for multi-axis applications. K-Cubes can be directly attached to the hubs while T-Cubes require a KAP101 Adapter Plate.

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.

Kinesis Software
Kinesis GUI Screen
APT Software
APT GUI Screen

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.

Thorlabs' Kinesis® software features new .NET controls which can be used by third-party developers working in the latest C#, Visual Basic, LabVIEW™, or any .NET compatible languages to create custom applications.

C#
This programming language is designed to allow multiple programming paradigms, or languages, to be used, thus allowing for complex problems to be solved in an easy or efficient manner. It encompasses typing, imperative, declarative, functional, generic, object-oriented, and component-oriented programming. By providing functionality with this common software platform, Thorlabs has ensured that users can easily mix and match any of the Kinesis 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 the low-powered, single-axis to the high-powered, multi-axis systems and control all from a single, PC-based unified software interface.

The Kinesis System Software allows two methods of usage: graphical user interface (GUI) utilities for direct interaction 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.

For a collection of example projects that can be compiled and run to demonstrate the different ways in which developers can build on the Kinesis motion control libraries, click on the links below. Please note that a separate integrated development environment (IDE) (e.g., Microsoft Visual Studio) will be required to execute the Quick Start examples. The C# example projects can be executed using the included .NET controls in the Kinesis software package (see the Kinesis Software tab for details).

LabVIEW
LabVIEW can be used to communicate with any Kinesis- or APT-based controller via .NET controls. In LabVIEW, you build a user interface, known as a front panel, with a set of tools and objects and then add code using graphical representations of functions to control the front panel objects. The LabVIEW tutorial, provided below, provides some information on using the .NET controls to create control GUIs for Kinesis- and APT-driven devices within LabVIEW. It includes an overview with basic information about using controllers in LabVIEW and explains the setup procedure that needs to be completed before using a LabVIEW GUI to operate a device.

Response from Mike at Thorlabs: In your screenshot you are trying to use the MG17Motor ActiveX object, however the TSG001 requires the piezo control ActiveX object therefore your program will not detect the strain gauge. You will need to insert the MG17Piezo.ocx ActiveX control object to operate the TSG001 in LabView. As you didn't provide any contact details please feel free to contact your local Thorlabs technical support group if you have any further questions.

Response from Mike at Thorlabs: For force sensors with a full bridge strain gauge you would need to use the Thorlabs AMP002 pre-amplification board before being able to connect this to the TSG001 strain gauge reader. I have contacted you directly with more information about the AMP002.

Update: After installing APT software v1.0.1 (rolling back from v3.3), the UI opens correctly. Still not sure why v3.3 does not work. Hello, when connecting the TSG001 (also connected to TPZ001 via cable, not the hub) to a PC running Windows 7 via USB and the APT software v3.3, the APT user interface does not appear. The TSG unit is powered and lit up, and the device driver installs correctly and is recognized as connected by the APT firmware, but the APT user program opens to an empty window and does not allow control.

Hello, when connecting the mains to the unit, I do not see any firmware display. Instead, the unit shows directly the position and the power, as well as the position LED, is blinking. I'm using this as shown on this page in conjunction with the TPZ001. I've followed the instruction by connecting both units to the power after connecting the units to my stage (TSGNFL5/M).
bhallewell  (posted 2014-09-04 07:51:01.0)
Response from Ben at Thorlabs: Thank you for your feedback here. The TSG001 will flash a three digit firmware version four times before it blinks a position value on power up. This value will continue to blink until the controller is 'zeroed'. An alternative way to retrieve the firmware version is within the APTUser software at the top right hand corner of the GUI. This value is contained within brackets. You can further query this reference within the APTFirmware utility.

Hello, Currently I'm using two TSG001 additionnally with four Tcube for DC control motors all plug in on one TCH002 USB HUB. I have developped specific software under Excel VBA to pilot the four DC motor and to simultaneously acquire two strain gauges so I used active X control to developed my soft and I have noticed that strain gauge reading function (SG_GetReading()) is not able to work at 500Hz as specified on the help, in fact when I'm pulling on the get_reading function the maximum sampling rate available is just 5Hz(200ms). It is very far away from the 500Hz ! How it is possible to have the good acquisition sampling rate ? Could send me an example of the VBA programmation which is able to sample these Tcube @500Hz ? Thank you in advance for your help. Sincerely, Eric Belot
msoulby  (posted 2014-01-28 09:49:00.0)
Response from Mike at Thorlabs: When acquiring samples via the USB interface the bandwidth will be limited. This is partially due to the latency of the USB messaging scheme and partially a result of the relatively slow analogue to digital data conversion process that takes place inside the TSG001. However the raw analogue signal allows a 500Hz bandwidth, so by using an external data acquisition device from the MONITOR output you could make use of the full 500Hz bandwidth.

Hi, I am using TPZ001 on TCH002 hub. I need to control the velocity of displacement. As aforementioned in my previous post, I tried the SetSlewRates Method Call in Labview but got error message. Seems this call not compatible with hardware...(only on BPC30x units). What shoud I do ? Sincerely, Mickaël
msoulby  (posted 2014-01-16 05:44:03.0)
Response from Mike at Thorlabs: The SetSlewRates method is only compatible with the higher specification benchtop controller BPC30x as you mention. However a work around could be to use an iterative loop within LabView. To do this in open loop mode you would use the method SetVoltOutput; by controlling the voltage step size and delay time between each iteration you can effectively create a quasi linear voltage ramp if the step size is small enough.

tcohen  (posted 2013-04-25 16:24:00.0)
Response from Tim at Thorlabs: Thank you for contacting us. Is the instability periodic or random noise and of what magnitude? The values should fluctuate somewhat to compensate for drift/noise. We will contact you to troubleshoot. For your second question, please see the SetSlewRates method. This sets the rate of change of voltage for open and closed loop operation.
j.dobrindt  (posted 2013-03-25 08:03:57.58)
A wrapper method that returns the force reading directly as a float value would facilitate interfacing with Matlab or Python. Such methods are available for the MG17Motor library (e.g., GetPosition -> GetPosition_Position). Will such methods be included in a software update or is there an easy workaround?
jlow  (posted 2013-03-27 13:09:00.0)
Response from Jeremy at Thorlabs: There is already a method for reading the output of the TSG001. It is the method SG_GetReading in the ActiveX control MG17Piezo.ocx. This is given in long format. You should be able to use the double(x) function in Matlab to convert the number to a double precision floating point value.

First off, if you start to type in a comment and then leave the tab with the intention of checking something and then coming back to finish the comment you find a blank input screen when you return... kind of painful. On this product, or any T-cube product i would expect to be able to get a very concise overview of the entire line. The basic premise of this line is the functionality offered by the entire family and the inter-play between the various modules, without the overview this presentation fails. I looked to the Related Items and then to the Accessories tabs for this overview (that's when i lost my comment) but to no avail. BTW, why do you force me to enter an email just to make a comment for your benefit, the Security Code okay that makes a little sense, but perhaps a little explanation under the box "To Prevent Website Spamming" or some such thing. Okay now i have another complaint, i left out the Security Code just becasue and my comment was wiped out again, but this time i was prepared for the weak implementation of a good idea, i copied the comment to my clip board so i could paste it right back. The little stuff really does matter.
