• Maxon motor control with LabView

  Hello everyone, I'm new here and I tried to find out how this process of work for some time and I ran out of options. LabView is very difficult to understand.

  I'm about to order a controller epos Maxon motor 24/5. I have a vi that does what I do, but I need to find a way to make the process faster. Basically will control a wing that goes forward and backward at very high speeds. I'm not sure what I should do, I would also like to generalize the process by a power enter a function or a wave of the position of my choice. If any of you all can help me it will be greatly appreciated. Thanks in advance.

  CarlosUT,

  Without the subVIs Epos, it is difficult to say where downturns could be.

  Take into account:

  1. the mathscript node is probably much slower than native LabVIEW, special code for what looks like a logic very simple.  Replace with the range of comparison functions.  Also consider the feedback node initialization so that you know where it starts when the VI is called.

  2. learn a few basics of data flow. Your delay (ms) and judgment is read only once at the beginning of the VI and these original values are passed to the loop. Any subsequent changes to these values will not see inside the loop. Move the terminals in the loop.

  3. double code: you have the same Subvi in each case in the structure of the case. Move the Subvi outside the structure of the case and simply use the box structure to choose which set of values will be used.

  4. given that the minimum value of the delay (ms) is 150, the loop cannot run more than about 6 times per second.  You don't specify what you mean by high speeds for the control of the wing, but this may be a factor.

• How to prevent getting started with LabVIEW, Matlab

  I have a few Matlab scripts in my vi and loading of the Matlab opens.

  I do not use it most of the time (it is for prototyping) so I was wondering if there is a switch that will leave Matlab to load or not with the beginning of the vi?

  Thank you

  Hi pawel,.

  You can try to use the conditional Structure to disable.  See its help herefile.  However, I don't think one of its default conditions will be particularly useful for you.

  It would be easier to place the code criminalized in a matter of Structure controlled by a Boolean simple button on your front.  If you want to run code, set the Boolean true.  If this isn't the case, set it false and let the piece fake the empty structure.  Who should take care of it.  Good luck with your codes!

• Time CONTROL of filterwhell fw102 thorlabs with labview

  Hello

  I'm looking for some someboby with experiences with the fw102 filterwheel of thorlabs (or something close).

  I just started with labview. I want to create a sequence for the filterwheel, so that the weel change of position after a defined period and all the filters are passed through.

  the problem is, that there are different sub-vis, but I don't know which to use. they are called "fw102x arrive in time", "get off time", "get time", "set time," "set off time" or "set the reading interval.

  Help, please!

  Thank you!!!

  Lucky-s

  I solved the problem!

  I don't need this time-screw, I use a while loop with delay.
  but thanks for those who think to my problem.

• Raspberry PI connected with usb for laptop with Labview

  Hello

  Please allow me to introduce myself: my name is Bob and I just graduated from the Bachelor of applied science (Physics), in the Netherlands. In education, I followed a course of programming in Labview. However, the course was not very well if I want to start from scratch. (my programming skills are very poor).

  My goal is to learn the basics of programming in Labview. I want to measure the temperature with a probe for example and read this in Labview. I need a data acquisition for this system. I have a raspberry PI in my possession and I was wondering if I could use it to read the temperature from the USB port of my laptop using the PI raspberry. Is this possible? And I have to run some sort of program on the raspberry PI? Or I could better use another device (Arduino maybe?).

  I hope someone could help me to help me get started with Labview. I'm looking forward to learn how to work with Labview and launch a few projects.

  Thanks in advance,

  Bob

  Are you comfortable with writing code on the invoice, pro forma raspberry? This is where you write the code for the acquisition of data and code to send it on the usb as a RS232 serial port. The LabVIEW program would receive all this and it is a very simple program. There is a tool called Linx box that does all this for the arduino.

• With the help of Lego sensors and motors through the LabVIEW and NI PCI card

  I want to connect a card PCI NI Lego motors and sensors and drive motors and the data of sense using LabView. What card PCI can I use? Thanks for a great site and fantastic community online.

  Hi Tom,

  Looks like a great app.  NXT with LabVIEW Migration will be a big intermediate step before joining more industrial and better sensors with a PCI, PXI, cDAQ or cRIO.  We have a lot of options when it comes to vision and control and acquisition of movement, and we have dedicated forums for all of these products as well.

• I want to simulate linear incremental encoder to Labview FPGA

  Hi all

  I use the card to FPGA OR 7851-R to simulate incremental linear encoder. I want to generate the impetus A and B of the map to simulate the features of linear incremental encoder according to the distance.

  I don't know how to do so please help me for the same thing.

  Have you tried to write any code yet? Why not start by generating just the channel has? It is a question of turning a digital channel on and off at regular intervals - a PWM with duty cycle of 50%. I think you can find examples of generation PWM is included with LabVIEW or on this forum. Then, to generate channel B, you must enter the code, but with the starting point offset by 1/4 of the period. Once it works, simply limit the number of periods of release based on the "journey".

  Look through the examples, write code and see how far you can get. When you get stuck, view the code that you have written on this subject and explain the problem.

• Linear actuator, motor controller and labview. Establishing a connection.

  Overview:
  I have a 12VDC linear actuator (potentiometer built in) connected to the and 21v3 Jrk USB motor with Feedback Controller (http://www.pololu.com/catalog/product/1392). Feedback from the actuator wires connect to the motor controller motor USB controller connects to the computer via USB.

  Problem:
  Establish the connection between the motor controller and labview.

  What I've done so far:

  I installed the drivers for the motor controller and windows detects it. OR MAX detects my motor controller (photo attached), but for some reason when I try to access it via the daq assistant in labview is not see it. I tried also access it through VISA with no result...

  Help will be appreciated.

  Thank you

  Peter

  You have some things you have to look in:

  • When you have installed the software, he was installing a USB > dll Com Port virtual as FTDIchip or similar? If so, when connect you your device, it will reveal itself as a normal COM (new) Port in Device Manager. You then try to talk to this COM port.
  • If you try to use the USB native on the map (as MAX has detected for you), then you will need to use the code in the .NET framework provided by the manufacturer (probably written in c#) and do your own builders in LabVIEW. If you have never done this before, it's not trivial.

  I would call the manufacturer and just tell them what you're trying to do. They have probably treated before LabVIEW and can have an example to help you get started.

  Edit: for fun, I followed the link you provided (which doesn't really). I searched "LabVIEW" of their site and indeed has achieved several successes. There is one thing that I downloaded (can't resist looking at code) was a gigantic turd. However, it doesn't use a standard Com port.

• Creation of a virtual circuit with LabVIEW

  Hello

  I am a student in first year engineering on a vacation of the summer research program. Literally just started using LabVIEW.

  My request - I can create a virtual circuit and then use LabVIEW for control switches/relay/circuit breakers in the circuit. My University has a microarray and my own research during the holiday season is to make an interface for this grid. The main objective is to control switches etc. using LabVIEW. And so to be a freshman with many prejudices against me (haha) it would be nice to use something virtual rather than something I could break.

  See you soon

  Then, we must understand what you want to do.

  If you want to simulate the whole shebang, you can do it.

  You can simulate buses, with expenses and supplies switches and vulnerabilities.  It's just math operations.

  After 37 seconds, the transformer to the 6-G node fails and draws excessive current, the circuit breaker for bus 6 breaks the circuit OK?

  I don't see what good that would do, but you could do it.

  If you really want to control the physical microarray, then you must have the interface hardware.

  Perhaps you need a digital I/o card, where iron 0 runs on the #6 bit 1 bus power depends on the load, and iron #2 turn on the load of over-current and you have the feeling that the CB tripped looking bit 8, and so on.

  Maybe you need an analog output, where you the value of the 130 V supply voltage and set the frequency to 65 Hz instead of 60.

  Maybe you need an analog input, where you measure the current at the point the circuit breaker is triggered and measure the voltage of the battery and so on.

  There are MIO devices with some of these areas, there are the specialized devices focusing on high performance in one of these areas.

  LabVIEW can control all.

  It will not be fun.  You can't plug the Council, launch LabVIEW and have it do what you want. You need to do some programming. It is much easier than using other languages, but it is not trivial.

  Hope that helps.

• How can I disable ads make my browsers - started with TB

  never, I installed Thunderbird I have now many "pop up" ads on my browsers. When I try to enter information in the fields of browser another browser window begins loading. It is negatively my purchase online. To disable them, please help me

  Sounds like malware. You can check your history on which you downloaded Thunderbird to? It is possible that it was a non-official package where Thunderbird was delivered with unwanted options.

  For Firefox on Mac, I suggest starting with your add-ons page. Either:

  • CMD + SHIFT + a
  • "3-bar" menu button (or tools) > Add-ons

  In the left column, click on Plugins. Set essential and unrecognized plugins 'never enable '.

  In the left column, click Extensions. Then, in case of doubt, disable (or delete, if possible) not recognized and unwanted extensions. All extensions are optional; none come with Firefox.

  Often, a link will appear above at least an extension disabled to restart Firefox. You can complete your work on the tab and click one of the links in the last step.

  Any improvement?

• Qosmio F30 starts with blue stripes during Vista boot screen

  My Qosmio F30-114 runs for years without problem with Vista Ultimate.

  In recent days, there is a huge problem.

  The Qosmio starts with blue stripes during vista boot screen.

  So I deleted the driver for the graphics card and used the standard vga driver for the card. the wizard of material found one driver on the system.
  For a brief moment, I was very lucky.

  After a reboot, there was a blue screen. After the next restard again once the driver to the standard vga card.

  What can I do?

  The download section of toshiba has no drivers for graphics card.
  And really... I wonder - how it works every year without problems...

  Someone at - it a solution?

  thanx

  toshibalover ;-)

  Hello!

  First you have this problem on an external monitor too or only on the screen internal? Maybe it s is not a graphics card problem so check it with an external monitor.

  I checked the Web from Toshiba site and I can find drivers for the Qosmio F30:

• NI 9148 with LabView module detection

  Hello

  I got the task of creating a deployable (compiled) software to a DAQ system with NI 9148 Ethernet RIO basket background and various modules. The user must have the ability to change the module type and the location of the different tests, so the application must detect (or the user specify) what modules are at what positions.

  I watched the blockset CRY, however this chassis is not supported and the lowest level blocks are protected. Is it possible to read the serial number of the modules connected to the 9148 OR position, type, and if all goes well?

  Thanks for any help!

• Watlow F4 controller with LabView

  Hi all

  I have a HX300 refrigerant in a closed circuit that uses a Watlow F4 controller. I want to control the F4 controller and monitor the conditions of it such as the rate of pressure and temperature using LabView. I heard about the pilot Modbus who helps make this communication possible and downloaded it. I use the version of LabView 8.6 and followed the steps needed to include it in Labview. I have very little experience with Labview and wonder how to start to write the code for this. Any help is very appreciated!

  Thank you
