11/2/2023 0 Comments Piezo actuator close up![]() The output drive voltage or position can be adjusted by rotating the software-pane control knob. 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. 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). 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. To support such a wide range piezo actuators these piezo units are fully configurable through software accessable key parameter settings. 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. 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. The BPC300 Series controllers have been designed for use in critical alignment applications where manual or automated nanometer level motion control is required. For details of the circuitry, please contact Tech Support. The controller measures a conditioned signal from the feedback sensor.Trigger Generation During Voltage Ramp Output User Input/Output (AUX IO) (15-Pin D-Type Female) Identification Resistor or Stage ID EEPROM in Actuator Position Feedback (PIEZO IN) (9-Pin D-Type Female) Other Piezo Driver Controllersġ00 ppm Over 24 Hours (After 30 min Warm-Up Time) If you need help identifying the appropriate replacement cable, please contact Tech Support. These ActiveX Controls can be incorporated into a wide range of software development environments including Labview, C++, and Matlab.Ĭables for connecting actuators or stages to the controller are shipped with the actuators or stages, not the controller. 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. For example, all relevant operating parameters are set automatically for Thorlabs' piezo actuated products. Coupling this with the user-friendly APT™ software allows the unit to get up and running quickly. Multiple units can be connected to a single PC via standard USB hub technology for multi-axis motion control applications. ![]() USB connectivity provides easy plug-and-play PC operation. Open- or closed-loop control and zeroing of the piezo can also be selected from the front panel. The display is easy to read and can be set to show either applied voltage or position in microns. 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. A waveform generation capability combined with triggering outputs make these units particularly suitable for piezo scanning applications. In addition, flexible software settings make these units highly configurable and therefore suitable for driving a wide range of third-party piezo elements. They have been designed to drive our full range of open- and closed-loop piezo-equipped nanopositioning actuators and stages. These single- and 3-channel, high-power (150 V) benchtop piezo controllers provide open- or closed-loop nanometer position control.
