• How can I work around a potentiometer that feeds a speed control using a SCC-AO10 module? Which wires I need to cut and where they connect to the SCC-AO10 module?

  I'm trying to circumvent a potentiometer that controls a blower DC motor. The potentiometer (10 kohm) has a wire greeen (+ 10V) a blue wire (ground) and a red wire (AI1 0-10 V voltage). These three sons feed a mounted ABB inverter which converts the 3 phases power somehow (220-240V) to a signal for the DC motor in the blower. I want to make a loop of speed control for the speed of the blower in Labview and I have to work around the knob. If I intend to use a PID that is equivalent to a speed measured at the speed setting, how can I get an output signal to my SCC-AO10 to the speed control? Asked me to use a switch that would allow to use potentiometer or the automatic control loop in Labview. Which wires should I cut the potentiometer and where I need to connect them on the SCC-AO10?

  Someone did this and the PID of a blower motor? Please help me if you can.

  «The promising (10 kohm) (10 kohm) potentiometer potentiometer has a wire greeen (+ 10V) a blue wire (ground) and a red wire (AI1 0-10 V voltage).» a greeen wire (+ 10V) a blue wire (ground) and a red wire (AI1 0-10 V voltage). »

  If you release the + 10V and the ground.

  The reader reacts to the voltage input (0 - 10V)

  Simply connect this red wire to your analog output module and ground (blue) on the floor of your module.

• Closed the motor current continuous Brushless PM and the loop speed control of Induction motor

  I need to implement the speed control of motors, asynchronous Motors PM Brushless DC and several other algorithms of cardiac control using LabView. It will take me 6-channel PWM and 6-channel 12 bit ADC, and a control movement of VI. Ideally a DSP would do the trick, but I would like to take advantage of the user-friendly interface of the LabView program to reduce development time. Please suggest the best hardware solution.

  Vaszzy,

  the SCB-68 is just a connection for the 7842R block and it does not provide a conditioning of signals. You can use digital IO of the RIO card to generate PWM signals. The 7842R provides converters a/d for voltage measurements. To measure the current you will need high precision resistors to convert current into voltage.

  Kind regards

• Understanding on the 9505 FPGA VI speed control

  I was able to quickly use the 9505 Servo Drive example for closed loop control of position on the FPGA, but I can't find how to change the code to take in charge the speed control (which I need to another axis).  I'm doing my changes on the FPGA VI itself rather than on the side of RT Softmotion.

  Here are the questions I have:

  If I use the PI speed loop with my speed and a set arbitrary control speed, I see the speed stabilizes (engine power seems uniform), but I can't correlate with the other speed reference that a larger number is faster.  Speed (from the loop of the encoder) seems collating in values from 0 to 2 just on my FPGA VI (I do not understand the units, but I see my position change on my collation of encoder in thousands of pulses per second).  Why are they so different/how I have adapted my encoder speed correctly?

  Using just the delivery example 9505 Servo Drive (position control), how to set the speed of moving of the FPGA code (in interactive mode)?

  Hello

  Speed is defined through position set points. Control of the speed in the screw RT does not actually send speed commands to the reader, but sends position set points at a known rate. Given that the position set points are sent at a constant rate, an effective speed can be calculated.

  A method to do so via the FPGA would synchronize a loop in your FPGA code for the analytical engine, which has a known rate. Once this is done, you can calculate the actual speed of the engine.

• What do you guys use of speed controls

  Hi all

  I have swpped my D - Link DIR-855 for a Linksys EA6500 and you want to check the overall speed.

  I use in my network devices as well as WiFi. I guess that speed controls should show the difference between wired devices, the devices connected to the Wifi or WiFi on a device of current line. www.Speedtest.NET does not seem to show this difference.

  What do you use to show the difference between LAN to the internet or LAN to NAS connection speeds?

  Kind regards

• Move a layer with a speed controlled by a slider.

  I would like to move a layer (X position) with a speed controlled by a slider of retouching. This would be trivial if AE script supported certain types of global variables. I would just like to add the current speed * frameDuration to the previous value. Any ideas on how this could be achieved given that the AE does not "remember" previous images?

• Reading variable speed and/or video frame-by-frame with waveform synchronization

  I use Diadem 2011 to view the data saved in a LabVIEW Module we wrote.  The function of our LabVIEW module is simultaneously video capture from two infrared cameras and 8 channels of waveform data acquisition data and record these data on the disk.  Data is stored in two files AVI (compressed) and a TDMS file (using logging TDMS).  With the help of tiara, use Sync video to view video files and data PDM.  I can scroll a cursor in the waveform data Panel and discovered the video corresponding to the chosen time.

  I'm looking for two features of the tiara that I'm not sure that are present: 1) a way to vary the playback of real time speed.  (2) a way to advance the video in a frame-by-frame.  If anyone has any suggestions on how I can implement this in 2011 tiara or can verify that these features are present, I wish I knew.

  Thanks in advance.

  Hello Resaebiunne,

  All the functions you are looking for are available in the toolbar.

  

  For functions/forward of frame market, make sure that the section with the video inside is highlighted and then use these two buttons. The "Cursor settings" icon let's you change the playback speed.

  Hope that helps,

• How to combine real-time video with LabVIEW indicators so that the video can be displayed and saved with the overlay data

  Let's assume for the moment that I can find a device for which LabVIEW has the appropriate drivers.  Is it possible to combine the camera feed with digital indicator fields so that there is a video out showing the data superimposed on the live image?

  I'm talking about something like a screen of the camera where you see the camera settings are displayed on the image in the viewfinder.  Note I have one isn't about analysis of video data or somehow reading parameters of the camera to the camera.  Data would be temperatures, pressures, speeds, etc., acquired by different instruments at the same time the video is captured and processed somehow by LabVIEW.

  No problem Wildcatherder, don't let me give you an overview of the process.

  When you get a video acquisition method entry, it will be an image format. Essentially, it's a bunch of images that are updated at the speed of video capture, just like the material. There are screws express (wizard - like elements) that simplify the obtaining of images from your video source. With the drivers and measurement and Automation Explorer installed, you should be able to get at least the image.

  If you have IMAQ toolkit, I mentioned, you could just wire the reference image (a purple wire wavy) and a text input (say, a temperature that is converted to a string) in the text overlay VI and it would produce the desired effect. Without this, you will need to convert the Image into image (these are two different data types in LabVIEW) and use the image instead, editing tools (essentially replacing pixels in 2D image data). You would then update an indicator of the photo with your photo altered, if all goes well to the pace of the acquisition hardware. As I said this is less elegant and can take a certain amount of time processor. If you view these images at all and are just their routing, it should be slightly faster.

  I don't know about video production equipment, I mainly used entry Firewire or USB, the computer screen or the file data. However, if the driver exists, it should be possible, but a quick review of the functions doesn't seem to come with output functions. Cannot advise on hardware, but you can start with:http://sine.ni.com/np/app/main/p/bot/no/ap/vision/lang/en/pg/2/sn/n17:vision, n21:11600 /?

  Hola Barcelona

  No you tiendo very well the pregunta respecto a en parte that need help.

  Respecto a lo del PID against este foro el cual tiene links in con PID information y controls Motors DC aunque vayas a usar para a CA, information engine you can be util además TR el control going to use usas UN PWM igualmente you serviria mucho gran parte the ahi esta info.

  Command PID made al control of DC motors

  Respecto al PIC the Comunicación y, mi primera mid-week seria using a PWM con UN cDAQ o una tarjeta and NO esa manera you mas eficiente el sistema control resultaria. Lo contrario seria UN media series utilizando el cable USB utililzar. O the third option you puedo recomendable usar UI an Arduino para which are hay una libreria Comunicación con cual ordered using LabVIEW seguir y UN mircontrolador sin tener as complicarte mucho.

• How to make a video in Labview that synchronize with the case data?

  Hi guys,.

  I do a program which displays the case data from a satellite to different positions. (For example, to position more near the Sun, the temperature data are higher...)

  To make the most interesting façade, I add in a video of a satellite in orbit around the Earth. The video must synchronize with the data that I show.

  My satellite orbital time is 90 minutes = 5400 seconds. If I use the method of control of ring photo, I have to import 5820 photo frames in the control of ring image. My understanding is that every time that the user can import an image (correct me if I'm wrong). That would mean that I have to import the photos in 5400 times.

  Is there another way to do this? I don't want to waste my time on the import of so many images.

  Vanessa

  If it's a video you have, I would have a look at the incorporation of some sort of video player in the façade through ActiveX. It is not something I've ever tried, but it should be possible and will save you having to generate 5000 + images!

  There is a resource here on the use of VLC with LabVIEW: https://decibel.ni.com/content/docs/DOC-24114

  If you can embed a video player and can be driven through ActiveX, then you should be able to do what you want!
