These single- and 3-channel, high-power (150 V) benchtop piezo controllers provide open- or closed-loop nanometer position control. They have been designed to drive our full range of open- and closed-loop piezo-equipped nanopositioning actuators and stages. In addition, flexible software settings make these units highly configurable and therefore suitable for driving a wide range of third-party piezo elements. A waveform generation capability combined with triggering outputs make these units particularly suitable for piezo scanning applications.

Manual controls are located on the front face of the unit to allow manual adjustment of the piezo position using the digitally encoded adjustment pot. The display is easy to read and can be set to show either applied voltage or position in microns. Open- or closed-loop control and zeroing of the piezo can also be selected from the front panel.

USB connectivity provides easy plug-and-play PC operation. Multiple units can be connected to a single PC via standard USB hub technology for multi-axis motion control applications. Coupling this with the user-friendly APT™ software allows the unit to get up and running quickly. For example, all relevant operating parameters are set automatically for Thorlabs' piezo actuated 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 tab. These ActiveX Controls can be incorporated into a wide range of software development environments including Labview, C++, and Matlab.

BPC301 GUI Panel

The BPC300 Series controllers have been designed for use in critical alignment applications where manual or automated nanometer level motion control is required. These high power yet low noise units deliver up to 150 V per channel and are compatible with all piezo-actuated nanopositioning actuators and stages in the Thorlabs range. They combine the latest high speed digital signal processors (DSP) with low-noise analog electronics and easy-to-use software technology for effortless software controlled piezo motion.

To support such a wide range piezo actuators these piezo units are fully configurable through software accessable key parameter settings. Intuitive, easy-to-use software graphical panels allow immediate control and visualization of the operation of the piezo controller – adjustment of many key parameters is possible through direct interaction with the graphical panel. Open or closed loop operating modes can be selected 'on the fly', and in both modes the display can be changed to show drive voltage or position (in microns). In the closed loop operation mode, both the P & I (proportional and integral) components of the feedback control loop can be altered to adjust the servo loop response. The output drive voltage or position can be adjusted by rotating the software-pane control knob.

Note that all such settings and parameters are also accessible through the ActiveX programmable interfaces which allow the user to build automated alignment routines. Refer to the Motion Control Software tab for further information on the apt™ software support for the BPC200 Series.

Waveform Output/Triggering

Over and above open and closed loop piezo positioning the DSP controllers within the BCP300 Series offer additional and useful functionality. Through software it is possible to program in a voltage (or position) ramp or waveform as a table of values and then instruct the controller to output (clock out) this table either 'single shot' or continuously. It is possible to specify a hardware output trigger to be generated at a specific point during the waveform output in order to control third party equipment as a function of the piezo voltage (position). Alternatively an external system can trigger the piezo unit to initiate the waveform output in the reverse scenario. This functionality is particularly useful for piezo scanning applications.

Full Software GUI Control Suite & ActiveX® Controls Included

ActiveX

A full and sophisticated software support suite is supplied with the BPC300 controller. The suite includes a number of out of the box user utilities to allow immediate operation of the unit without any detailed pre-configuration. All operating modes can be accessed manually and all operating parameters changed and saved for next use. For more advanced custom motion control applications, a fully featured ActiveX® programming environment is also included to facilitate custom application development in a wide range of programming environments. Note that all such settings and parameters described above are also accessible through these ActiveX® programmable interfaces. For further information on the apt™ software support for the BPC300 units refer to the Motion Control Software tab. Demonstration videos illustrating how to program the apt™ software are also available for viewing.

The ActiveX® apt™ system software shipped with these units is also compatible with other apt™ family controllers including our multi-channel rack-based system and smaller optical table mountable 'Cube' controllers. This single unified software offering allows seamless mixing of any apt™ benchtop, table top and rack based units in any single positioning application.

The key innovation of the apt™ range of controllers and associated mechanical products is the ease and speed with which complete automated alignment/positioning systems can be engineered at both the hardware and software level. All controllers in the apt™ range are equipped with USB connectivity. The 'multi-drop' USB bus allows multiple apt™ units to be connected to a single controller PC using commercial USB hubs and cables. When planning a multichannel application, simply add up the number and type of drive channels required and connect together the associated number of APT controllers.

Piezo Driver Bandwidth Tutorial

Knowing the rate at which a piezo is capable of changing lengths is essential in many high-speed applications. The bandwidth of a piezo controller and stack can be estimated if the following is known:

  1. The maximum amount of current the controllers can produce. This is 0.5 A for our BPC Series Piezo Controllers, which is the driver used in the examples below.
  2. The load capacitance of the piezo. The higher the capacitance, the slower the system.
  3. The desired signal amplitude (V), which determines the length that the piezo extends.
  4. The absolute maximum bandwidth of the driver, which is independent of the load being driven.

To drive the output capacitor, current is needed to charge it and to discharge it. The change in charge, dV/dt, is called the slew rate. The larger the capacitance, the more current needed:

Piezo Equation 1

For example, if a 100 µm stack with a capacitance of 20 µF is being driven by a BPC Series piezo controller with a maximum current of 0.5 A, the slew rate is given by

Piezo Equation 2

Hence, for an instantaneous voltage change from 0 V to 75 V, it would take 3 ms for the output voltage to reach 75 V.

Note: For these calculations, it is assumed that the absolute maximum bandwidth of the driver is much higher than the bandwidths calculated, and thus, driver bandwidth is not a limiting factor. Also please note that these calculations only apply for open-loop systems. In closed-loop mode, the slow response of the feedback loop puts another limit on the bandwidth.

Sinusoidal Signal

The bandwidth of the system usually refers to the system's response to a sinusoidal signal of a given amplitude. For a piezo element driven by a sinusoidal signal of peak amplitude A, peak-to-peak voltage Vpp, and frequency f, we have:

Piezo Equation 3

A diagram of voltage as a function of time is shown to the right. The maximum slew rate, or voltage change, is reached at t = 2nπ, (n=0, 1, 2,...) at point a in the diagram to the right:

Piezo Equation 4

From the first equation, above:

Piezo Equation 5

Thus,
Piezo Equation 6

For the example above, the maximum full-range (75 V) bandwidth would be

Piezo Equation 7.

For a smaller piezo stack with 10 times lower capacitance, the results would be 10 times better, or about 1060 Hz. Or, if the peak-to-peak signal is reduced to 7.5 V (10% max amplitude) with the 100 µm stack, again, the result would be 10 times better at about 1060 Hz.

Triangle Wave Signal

For a piezo actuator driven by a triangle wave of max voltage Vpeak and minimum voltage of 0, the slew rate is equal to the slope:

Piezo Equation 8.

Or, since f = 1/T:

Equation 9

Square Wave Signal

For a piezo actuator driven by a square wave of maximum voltage Vpeak and minimum voltage 0, the slew rate limits the minimum rise and fall times. In this case, the slew rate is equal to the slope while the signal is rising or falling. If tr is the minimum rise time, then

Equation 11

or

Equation 12.

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.

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.

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.

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.

The APT video tutorials available here fall into two main groups - one group covers using the supplied APT utilities and the second group covers programming the APT System using a selection of different programming environments.

Disclaimer: The videos below were originally produced in Adobe Flash. Following the discontinuation of Flash after 2020, these tutorials were re-recorded for future use. The Flash Player controls still appear in the bottom of each video, but they are not functional.

Every APT controller is supplied with the utilities APTUser and APTConfig. APTUser provides a quick and easy way of interacting with the APT control hardware using intuitive graphical control panels. APTConfig is an 'off-line' utility that allows various system wide settings to be made such as pre-selecting mechanical stage types and associating them with specific motion controllers.

APT User Utility

The first video below gives an overview of using the APTUser Utility. The OptoDriver single channel controller products can be operated via their front panel controls in the absence of a control PC. The stored settings relating to the operation of these front panel controls can be changed using the APTUser utility. The second video illustrates this process.

APT User - Overview
APT User - OptoDriver Settings


APT Config Utility

There are various APT system-wide settings that can be made using the APT Config utility, including setting up a simulated hardware configuration and associating mechanical stages with specific motor drive channels. The first video presents a brief overview of the APT Config application. More details on creating a simulated hardware configuration and making stage associations are present in the next two videos.

APT Programming

The APT Software System is implemented as a collection of ActiveX Controls. ActiveX Controls are language-independant software modules that provide both a graphical user interface and a programming interface. There is an ActiveX Control type for each type of hardware unit, e.g. a Motor ActiveX Control covers operation with any type of APT motor controller (DC or stepper). Many Windows software development environments and languages directly support ActiveX Controls, and, once such a Control is embedded into a custom application, all of the functionality it contains is immediately available to the application for automated operation. The videos below illustrate the basics of using the APT ActiveX Controls with LabVIEW, Visual Basic, and Visual C++. Note that many other languages support ActiveX including LabWindows CVI, C++ Builder, VB.NET, C#.NET, Office VBA, Matlab, HPVEE etc. Although these environments are not covered specifically by the tutorial videos, many of the ideas shown will still be relevant to using these other languages.

Visual Basic

Part 1 illustrates how to get an APT ActiveX Control running within Visual Basic, and Part 2 goes on to show how to program a custom positioning sequence.

LabVIEW

Full Active support is provided by LabVIEW and the series of tutorial videos below illustrate the basic building blocks in creating a custom APT motion control sequence. We start by showing how to call up the Thorlabs-supplied online help during software development. Part 2 illustrates how to create an APT ActiveX Control. ActiveX Controls provide both Methods (i.e. Functions) and Properties (i.e. Value Settings). Parts 3 and 4 show how to create and wire up both the methods and properties exposed by an ActiveX Control. Finally, in Part 5, we pull everything together and show a completed LabVIEW example program that demonstrates a custom move sequence.

Excuse me,could i change the output voltage frequency when i use the BPC301, and output a high frequency voltage?
cwright  (posted 2020-10-14 08:23:59.0)
Response from Charles at Thorlabs: Hello and thank you for contacting us. The output voltage (open loop) or position of the piezo actuator(closed loop) can be controlled from an external source via the EXT IN (+) and EXT IN (-) BNC connectors on the rear panel. The exact bandwidth achievable is dependent on a variety of factors, such as the load capacitance but in general is a few kHz in open loop mode and about 200 Hz in closed loop. For more details on configuring the EXT IN connections please see section 3.3 of the manual and the Piezo Bandwidth tutorial on the website: https://www.thorlabs.com/NewGroupPage9.cfm?ObjectGroup_ID=1912&tabname=Piezo%20Bandwidth

Dear Thorlabs. We have got your BPC 301 controller . The problem is that the controller does not change the voltage and the position neither by the front panel nor by the software.I keep getting an internal error#16510403/Error; [Code=1252] power supply error. The front panel shows 0.60V and when turned onto closed it continues to oscillate +/-0.05 or so. As it oscillates, in the APT User window I get a new window every second with the same error. How do I increase the voltage? Please advise on possible solution.

Is it possible to use this PZT controller to specify applied force over time instead of displacement over time?
bwood  (posted 2017-08-18 05:17:13.0)
Response from Ben at Thorlabs: Thank you for your question. The BPC has a force sensing mode, based on the the strain gauge feedback. You can configure the device for this in APT/Kinesis. One example of this functionality is with the FSC102. There is no way to directly output the force output by the piezo, but you could calculate it, see the piezo tutorial here: https://www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=5030

While the controller works perfectly fine manual and with the delivered APT software, we have some difficulties using Labview. The correct ActiveX control for the ThorLabs BPC303 APT Piezo Contoller is used ('MGPiezo') and we used the SN given by the APT software. The Labview is configured as given by examples files. However still Labview returnes the error: "Control HW Communications Disabled " We also try selecting user interface as preferred execution stystem under File >> VI Properties >>Execution tab. Are we missing something obvious?

I am currently using a BPC 203 controller with Nanomax 311 and also with APB 301 translation stages. However, I would like to purchase a new 3 axis translation stage with larger scale (and possibly a better linearity). No piezo stage with large range are available anymore in Thorlabs catalogue (with a dynamic range up to 100-300µm). Therefore, I wonder if it would be possible to use third party translation stages (for example from PI or PiezoJena or others...) while keeping the Thorlabs controller beacause I already spend a lot of time developping LabVIEW software for BPC203 controller. If I need a BPC303 (150V) that could be possible...
msoulby  (posted 2014-12-08 03:52:54.0)
Response from Mike at Thorlabs: At this time Thorlabs does not have a 3 axis stage with 100-300um of piezo travel. However there is no reason why the controller would not work with a third party piezo providing the piezo falls within the drive voltage specification of the controller, which is 0-75V and 500mA per channel for the BPC203. However please bear in mind that Thorlabs piezo stages that have strain gauge feedback use an auto ID resistor to tell the controller how much travel the piezo stack has and selects the correct voltage range accordingly (not applicable to open loop control and piezos) this may not be available on a third party stage so it may need to be configured manually. Also as any thir party stage will not have been tested by Thorlabs we would be unable to guarantee the stage will operate to the spec that the competitor claims and would not be responsible for any damage caused by using such a third party stage.

Dear Thorlabs. We have got your BPC 203 controller along with the Nanomax TS stage. The problem is that channel no.1 of the controller does not change the voltage and the position neither by the front panel nor by the software. The front panal shows -12.3 V irrespective of the position of turning knob and the zeroing button. Other two channels are okay. Please advise on possible solution.

Response from Javier at Thorlabs to last poster: Thank you very much for your feedback. We have added the piezo drive cables as related products to the pages for the BPC controllers and the NanoMax stages. We will also add a information on the Features section of these products to make it clear that the drive cables are not included with the controller, but are included with the stages. Please contact us at techsupport@thorlabs.com if you have any further questions or comments.

It would be useful to add the drive/feedback cables as a related product for either this page or the NanoMax pages. As of now, it is very unclear as to whether these are included with the controller, the stage, or not at all.

A response to sylvain from Adam at Thorlabs: We have already responded to you via email, but wanted to update the response on our website as well. Since this feedback, We have looked into our supply of USB cables and have insured that they are all certified high speed USB cables. Currently, we do not have a complete software solution for non Active X users, but we do offer a low level comms protocol document for customer that want to program their own non Active X based software. We expect to add the piezo protocols to this document in the upcoming weeks.

I recently start using BPC203 with MAX313 to control scanning near field microscope and i have two comments: - first, the USB port of the controllers needs good quality USB A/USB B cable to avoid problems (I spent few times to discover that some troubles in the communication were due to the cable...) - it is sad that Thorlabs could not provide solutions other than Active X for programmers who prefer to develop their codes under Linux. Any solutions in this case?? Best regards

A response from Ken at Thorlabs to noah: We do have some tutorial videos on APT Programming using Visual Basic. Simply click on the Video Tutorials tab on this page, click "here", then click on APT programming.

Hi, I am new to visual basic, though I have extensive programming experience in other languages. I am having trouble writing vb6 code to control my BPC202 and my BPS 103. Structuring the code and calling procedures from the included libraries to create timing-sensitive & predictable object-oriented programs is rather difficult in VB, as I find myself having to guess how VB6 will sequentially execute a program, modify variables in "real time" etc. I would like from you, if possible, a version of the apt-server.hlp file compiled into a printable .pdf or something similar (rather than printing every topic individually). Better yet, a more descriptive yet concise introduction to scientific computing with VB (via Thorlabs APT products) would be a lifesaver. It would also be great if you had a repository of code that users could submit to and draw from as a learning tool; even if the code were not checked for bugs or vouched for by Thorlabs, it might help to see how others structure their programs. Any old help files or internally developed VB code snippets (the included examples are a good start) that youd be willing to share with me would be great, too.

Response from Laurie at Thorlabs to melsscal: Thank you for your interest in our BPC203 controller. To control the piezos on the MAX313/M, you can use the BPC203 controller. Other options include the BNT001 and the TPZ001. Please let us know if you have additional questions.

Can we use BPC203 with MAX313/M as Non Track Controller ?

PHS101 remote control device is missing from this presenation (not even posted as a related product), i would add this right into the current presentation in summary with a link to the PHS01 product page. Ideally i would like to be able to order both products from this page.

The MZF001 joystick console has been designed to provide intuitive, tactile, manual positioning of our range of piezo-based stages. It is used in conjunction with the single- and 3-channel controllers described above, enabling full control of the piezo actuators in situations where the application is at some distance from the controller, thereby allowing convenient adjustment of the output while monitoring the alignment. This is useful when working in a complex optical setup, where access to the front panel controls or adjusting controls on the PC is impractical. Furthermore, if the parameter settings are saved (persisted) to the controller, the controller need not be connected to a host PC, thereby allowing remote operation.
