• Engine step doesn't fail before reaching its physical limits for the sinusoidal movement

  Hello

  My ultimate goal is to skip a XY (via 2 linear actuators) in a circular motion (radius of 0.47 ") at a frequency of 1 Hz. I run the example VI 'Demo circle' which received my copy of LabView, version 9.0.

  The problem I encounter is that given the physical limitations of the engine and the drive motor, the task should technically be feasible (see calculation *). However, even when the engines are completely discharged (no not attached to anything whatsoever), they start missing steps away from my final goal. I'm only able to reach a radius of 0.2 "(vitesse de pointe de 1.25" / seconde). "

  My question; Is the system set up incorrectly or is my final goal unrealistic, given performance reductions inevitable due to software/hardware?

  I apologize for the naivety of this question, but if there is any information that you may provide which might shed some light on this problem, I would be very happy.

  Possible theories:

  Torque is decreased more at high speeds because of microstep

  A closed loop system would improve performance at high speed

  The VI 'Demo circle' is not the best method to create a circle

  The acceleration is the limiting factor, not speed

  * RADIUS = 0.47 "

  Maximum speed = (RADIUS * 2 * pi) * cos(2 * pi)

  Maximum speed = 2.9 "/ second"

  System:

  LabView v9.0

  PCI-7340

  open loop configuration

  MID-7604

  1 4 a per axis

  10 micro steps

  Linear actuator (form is attached)

  NEMA 17 ordered by motor (sold by ultra-motion).

  Maximum speed of 3.3 inches per second

  1. 2A voltage coil

  1.8º step angle

  Kind regards

  Nick-

  I really wonder the max speed in the datasheet.  0,0833 "/ to 3.3" rev / s = about 40RPS (2400 RPM), which is extremely fast for a motor, especially at 24VDC.  Know exactly what engine is on the cylinder and go to www.applied-motion.com and you should be able to find curves of torque for that or a similar engine with various readers.  You will see that couple to 24VDC curves are not good.  In addition, ask Ultramotion if their speed/strength curve is theoretical, or tests have been conducted.

• Thunderbird is stuck in the loop. Can not stop in the Task Manager.

  links will not open in thunderbird. I followed the instructions in this link: http://www.ghacks.net/2013/01/20/fix-for-thunderbird-not-opening-links/.
  After you set the 3 True values, I left and restarted thunderbird.
  I then clicked on a link in an e-mail message and the LAUNCH APPLICATION box appeared.
  I accidentally entered "thunderbird" instead of "firefox".
  When I clicked on the link in the e-mail, it goes into a loop where the hourglass icon will flash constantly.
  I couldn't go back to the LAUNCH APPLICATION window to change.
  Then, I deleted the Thunderbird folder in program files and reinstalled thunderbird OK.
  Everything works fine until I click on a link in a message. He then goes into the loop, and I have to restart.
  Is there something in the registry that I can change to fix this?
  Thanks for any help you can offer.
  Kind regards
  Geoff Wight

  Go to the menu Tools (alt + T) > options > attachments and delete any reference to Thunderbird.

  Change the preferences to their default values. by https://support.mozilla.org/en-US/kb/Hyperlinks-in-Messages-Not-Working#w_check-for-an-incorrect-preference then you can read any article that the incorrect pref is usually only a question after using the Thunderbrowse add-on.

• Loop slider does not appear when you move to the right of the loop; may not extend the duration of the loop; aaarrrgh.

  Have checked tutorials and help , but doesn't understand why hovering over the right angle, at the top of the track loop not give me the slider that allows me to draw on the track and extend the playback loop.

  Long kickflip is the one that gives me a problem right now, but Latin Bembe Cowbell does not work for me either!

  It is my first try at GarageBand, and maybe my last very soon.  Thanks for easy to understand help you send.

  The two loops work very well for me in GarageBand 10.1.1. Skip on the upper right corner of the audio region to display the cursor of the loop, if it is not, save your project and the test in a different project.   Restart your Mac, if you don't have already done.

• Color of the loop?

  Hello!

  You have an idea how I can choose the color (Silver/Gold) of the loop, when I buy the new strip of woven nylon?

  There is no option for this:)

  Hey Gabor

  Bands of woven Nylon loops of silver or other than the black band, which has a black loop.

• NOON adding loops to the loop browser

  I recently bought a few loops Loops the Looploft and Platinum. Some were the rest of MIDI and audio. Audio loops added very well. LUNCH will however not appear in the loop browser when adding. Is there a procedure I need to follow? I've just them slipped into the loop browser in the folder I copied in my home folder. Logic has done its thing spinning for a while, but never added loops.

  (1) Midi Apple Loops (green) are not the same as plain old loops Midi... so adding plain loops Midi for the Apple loop browser will not work... and therefore will not show in the loop browser. Regular midi loops can be simply dragged into the window Finder arrangement or the logic file browser.

  (2) to create an Apple Midi loop... (Green type) so you can add it in the loop browser... You must create a noon... with software instrument region etc... Select that region and then right or command to the left... click it to bring up the context menu and choose export > add to the loop library and fill in the relevant details in the next dialog box...

  Note: Can not find the export function? Turn on ALL the advanced tools in the preferences of Logic...

• HP Z600: What processors am I limited with the hpz600 workstation?

  Hi, I have a HP Z600 that I bought refurbished. The vehicle currently has 2 x Xeon X 5560 2.8 cpus.

  I am struck with this configuration cpu load limit (I run the intensive 3d modeling software), and I want to improve.

  Am I limited with the motherboard on these workstations?

  Which processors that you would recommend? (I looking for a quite intensive help and have a few hundred dollars to spend).

  Thank you!

  anti1, older versions of the Z600 support microprocessors Intel 55xx only, later versions support as 55xx 56xx CPUs.  The best way to determine this is to boot the system, enter the BIOS F10 setup and look at the date of starting block.

  If the boot block date is 03/01/2009, the system supports the 55xx only processors.

  If the block start date is 07/01/2010, the system supports processors 55xx both 56xx.

  -C' is the block of start date, not the date of the version of the BIOS.

  -There is no way to update the boot block.  (There are several discussions in this forum about this)

  If your system has the block to start later, upgrade to a 6 core CPU 56xx will give best performance.  I think that the frequency of the processor 6 c is 3.47 GHz, although there is a 4 processor 3.6 GHz.  Your application supports multiple cores?

  To get an idea of any increase in performance, look at the reference site of CPU of the pass mark for the top processors of range, here.

  Based on these landmarks (I know, they are markers without real object numbers), you could get about 70% performance increase by using a X 5690 6 3.47 GHz CPU core.  Is it enough for your application?

  Sorry, but the restriction password cannot be reset, it is part of the backup and restore a backup that was taken after the restrictions were activated, restore this code again.

  You will have to start without the help of the data backup, configure the phone to factory settings and start over. Follow the steps mentioned in this article:

  If you lose or forget your password restriction, you must erase your device and then put it up as a new device to remove the restriction password. Restore the device by using a backup does not delete the access code.

• Limits of the skeleton L

  Hello

  I'm stumbling on the limits of the function of the skeleton, and IMHO, they are about size.

  Suppose I'm workign with a large image... 2048 * something.
  What I get from the skeleton L-function is

  

  (I know, skeleton lines are barely visible. What matters is the "block in the Middle"... aka skeleton function overflows)

  It's the same operation to the size of the image 600 * 355px (which isn't important in my humble OPINION)

  

  Only with a frame size of 230 x 160 or more, I'm getting a "real results".

  

  I'm not really happy with this behavior and lose a LOT of details here.

  I have two suspicions:
  one) somewhere, the data is stored in a U8...
  (b) IMAQ skeleton is probably derived from the thinning skeletonized, which in turn is probably based on the morphology of the IMAQ. IMAQ morphology begins to be unreliable after a 100 iterations of magic...

  Did someone of NO can give more information? I'll probably have to re - implement the whole thing... but I would like to at least know where / IF I can trust this algorithm to a certain particle size.

  Thank you
  B

  Just for anyone who actually search for the topic: I finished my own algorithm of skeleton. It works, there is no size limitation (beyond distances U16 ) and 84 x (upon my request) is as fast as the NOR one.

• WHY? C program = No delays, Labview delays = > > Intermittent delays in the loop of RS232 serial subroutine 115200 baud. Windows 7 LV 2012

  In 30 years of developing LabVIEW I saw such a strange problem.    Maybe someone can help out me.

  Here's the problem:

  Ms 1 000 large delays occur intermittently in two instances of an executable of LabVIEW with exact system.  (SEE ATTACHED time STAMP of SCREEN CAPTURE FOR 11 and 14 COM COM where there was a > 1000 ms delay)

  • Subrotine RS232 communication loop were brought in the course of a program of 'C' that has held rock solid and did not have this same problem.
  • No record on the hard drive is in this subroutine, communication comes standard.
  • The executables are running on the same high performance server DELL 7910 communicating with satellites in Earth orbit, 24 x 7.   (RS232 115 200 Baud, Windows 7, 6 son of processor).
  • An executable uses COM 11 and the other uses COM 14.
  • The executable has the critical loop "subroutine" that injects data REVIEWS, if there is more than a 100ms delay.
  • The subroutine is not reentrant, because it is the only case used throughout the program.
  • I placed the time markers in the loop of the subroutine which tell me exactly where in the code the delay occurred.  In most but not all cases, that the delay occurs at the 'WAIT MS' or 'WAIT until the NEXT MS MULTIPLE', I tried them both, and they both have the same intermittent problem.
  • What gets me, is that the executables that are run independently of each other are logging the delay at EXACTLY the same moment.    This leads me to believe that it is a question of operating system.  Or a problem that the two executables have when competing for time to critical system resources.
  • This problem of intermittent delay occurs on other computers and on windows XP
  • The large delay occurs even when there is only one executable file running.
  • This problem is particularly bad , when the user resizes or drag the window to the executable.
  • If the system is left alone, the problem of > 1000 ms delay can happen only once or twice a day.
  • I have not yet attempted to set the priority or affinity processor running in the Task Manager
  • The executable runs as well some other non-critical time loops that perform SQL database entries, you connect the hard drive, then state machine management.

  Would like to hear from someone about it.

  Thank you

• RunState.ProcessModelClient. how to access the results of markets located in the loops?

  Hello

  In my sequence, I have to perform an analysis of the results before I have the MainSequence and return to the process template. Basically, I need to check made some steps has passed.

  I access the results using RunState.ProcessModelClient. Using what I have access to the list of results. I would like to write that I have access to each result but I can't because I spotted the results of steps which are curly are not accessible (they are not there); However, they are on the report.

  How is it possible? How do I access results in a loop? Where are they?

  K.

  Hello

  not too painful:

  the loop results in the usual place online, it's just the layout that will look like a little confusing:

  You use some revisions of my TestStand (you are in 3.1)

  

  The Runstate.ProcessModelClient is actually a copy of the space of time edit, not space running - it's the SequenceFile type, which means that even if you can see the layout of the result containers that belong to each step, they are there permanently, and not filled in this place from the moment of execution.

  At the level of the mainsequence, you're still in your client, then you can go to Locals.ResultList directly.

  In there, you have the singular element that is the result of the first and the only stage of your Mainsequence of your.

  Inside there is the. TS. SequenceCall container. It is effectivey the resultlist gait that calls (always Mainsequence) seq1 so inside that, there is an another ResultList.

  It's the ResultList for sequence "Seq1".

  Which has a single item since this sequence has only one step inside of type SequenceCall.

  [0]. TS. SequenceCall.ResultList.

  From there you can see a lot of results even if you have only 4 effective steps in this sequence.

  12 results covers:

  3 iterations of ('for' 'Test2' 'end').

  and then the last 3 items are "Test1" loop 2 times more.

  When you set a stage of the loop and include you the results of each iteration, you get these results (2 in your case) more a global success-failure based on the criteria (your care ot 100% must pass in order to study the step successful when all iterations are complete.)

  Note in your pre Expression where you change the name of the step on the fly, your labeled Test2 incremental changes the name from 'Test1' + Str (Locals.LI), and the Test1 marked step uses the same expression for this will look slightly confused that you cross your results.

  Hope that helps.

  Thank you

• Then as the loop timer Timing vannes_ouvertes. Elements

  I would like this while loop to iterate through every second. But it seems that he doesen't recognize the loop timer. What's wrong?

  

  Just found the article to help talking about it: Debugging of FPGA screws using Mode Simulation (FPGA Module)

  At the bottom, it says:

  Understanding simulated time on the host computer

  If you use some FPGA resources and you run the FPGA VI in simulated using I/O simulation mode, the resource uses simulated time rather than real time. Simulated time could be faster than real time according to the number of events that occur during the simulation. For example, if you add a waiting VI (simulated time) for the schema and set the timeout to 1000 ms, LabVIEW does not attempt to delay a second of real time. Instead, LabVIEW delays as long as necessary before performing the next action scheduled in the simulation.

  The following resources are using the simulated time on the host:

  • Then the loops
  
  
  • Single-Cycle timed loops
  
  
  • VI of waiting (simulated time)
  
  
  • Loop timer Express VI
  
  
  • Number of cycles Express VI
  
  
  • FIFO, except DMA FIFO
  
  
  • Wait on Occurrence with Timeout based on ticks
  
  
  • Interrupt the VI, during her wait until this that clear is TRUE
