The BDC103 DC Servo Motor Controller is ideal for motion control applications requiring high speed (up to 100 mm/s), high load (>10 kg), and high resolution (<1 μm) capability. It is capable of driving larger framed DC brushed motors up to 50 W and equipped with encoder feedback. The BDC servo controller has been engineered to provide a seamless alternative to our BSC series stepper controllers particularly where high-speed, closed-loop operation is important.

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 very user friendly apt™ software allows the user to very quickly get up and running with reasonably complex move sequences in a short space of time; for example all relevant operating parameters are set automatically for Thorlabs stage and actuator products. Advanced custom motion control applications and sequences are also possible using the extensive ActiveX® programming environment described in more detail on theSoftware tab.

We have ensured that the software interfaces to the BDC series are highly integrated with all other apt™ family controllers, providing easy system integration and reduced learning curve. As one of the newest members of the apt™ family of controllers, these units are backed up by the fully featured apt™ suite of PC software tools for immediate and easy out-of-the-box configuration and usage.

This controller is recomended for use with high power, large framed DC servo motors. For control of the Thorlabs Z8 series or other low power DC servo motors please see the TDC001 DC Servo Motor Driver T-Cube.

*Location-specific power cord supplied.

Driver Flexibility

A wide range of brushed DC servo motors and associated actuators are available, each with its own operational specifications. For this reason, the apt™ DC Servo controllers are fully configurable (parameterized) to support different motor/actuator combinations. Key settings such as PID control loop values, min and max stage position, leadscrew pitch, and limit switch configuration are exposed through the supplied apt™ software. Moreover, relative and absolute motion can be initiated with move profiles set using velocity profile parameters. Homing sequences for establishing a zero datum are also fully configurable for a particular stage or actuator. For simplicity of operation, the apt™ software incorporates pre-configured settings for each Thorlabs' stage and actuator including the DRV414 actuator.

All key parameters can be adjusted through direct interaction with the graphical software panels supplied. However, for custom motion control applications, all controller settings and commands are also accessible through the ActiveX ® programming libraries. These programming libraries are very comprehensive, providing hundreds of functions and parameters that can be accessed from user-written programs. They are language independent in nature and consequently are supported by a large variety of programming environments that are ActiveX ® compliant. These include LabVIEW, Visual Basic, C++, Matlab, and HPVEE.

Note that all such settings and parameters are also accessible through the ActiveX® programmable interfaces for automated alignment sequences. Refer to the Software tab for further information on the apt™ software support for the BDC100 series.

Full Software GUI Conrol Suite & ActiveX® Controls Included

A full and sophisticated software support suite is supplied with the BDC103. The suite includes a number of 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 can be changed and saved for next time 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 BDC10x refer to the Software tab. Demonstraton videos illustrating how to program the apt™ software are also available for viewing from the Video Tutorial tab.

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 T-Cube Controllers. This single unified software offering allows seamless mixing of any apt™ benchtop, table top and rack based units in any single positioning applicaiton.

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 commerical USB hubs and cables. When planning a multi-channel application, simply add up the number and type of drive channels required and connect together the associated number of APT controllers.

Encoded Feedback - Positioning Accuracy

The BDC100 series controlers also support encoder feedback on each channel through dedicated quadrature encoded pulse (QEP) inputs. A built in algorithm can be enabled to allow the servo system to reach and maintain an encoded position through a highly configurable iterative move sequence. For custom closed loop algorithms the apt™software exposes the encoder position for access through the ActiveX® programmable interfaces.

Software Developers Support CD

A developers’ kit is shipped with all of our apt™ series controllers. This additional software support is intended for use by software developers working on large, system integration projects that incorporate apt™ products. The kit contains an extensive selection of useful code samples as well as a library of Video Tutorials.

The APT (Advanced Positioning Technology) family covers a wide range of motion controller products ranging from small low powered single channel optomechanical motor drivers (the 'Cube' drivers) to high power multi-channel modular 19" rack nanopositioning systems (the APT Rack System).

All controllers in the APT family share a common software platform, the APT System Software. The software CD supplied with all controllers contains an installation of this system software, together with a wealth of support information in the form of handbooks, help files, tutorial videos, FAQs and other relevant information on using and programming these Thorlabs products.

By providing this common software platform, Thorlabs has ensured that users can easily mix and match any of the APT controllers in a single application while only having to learn one 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 APT System Software allows two methods of usage - graphical user interface utilities (supplied) 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 progammed in the development language of choice.

Detailed information on both usage modes is provided on the CD.

Also of particular interest is the inclusion on the software CD of a range of software video tutorials (see the Video Tutorials tab). 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++.
