Find physical limits without limit switches.

• 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

  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.

• A thief can remove a device to find my phone without the icloud password?

  My ipad was stolen and I have it marked as 'lost mode' in icloud find my phone. A month later, I see that the device is disappeared from my icloud account?

  The device had an access code, but it was a simple because my children use it.

  My question is, if the thief has guessed the password device, can remove the device from the icloud or find my phone without knowing the password to icloud?

  Hi there Habine,

  So you're worried about whether or not someone can disable find my phone if they are able to guess the password and enter in your iPad. According to this article on find my Activation lock phone, no, they can't:

  Find my iPhone Activation Lock

  How does Activation lock?

  When you enable find my iPhone on your iPhone, iPad or iPod touch, your identifier Apple is securely stored on the activation of Apple servers and connected to your device. From then on, your password will be needed before anyone can turn off Find My iPhone on your device, erase your device, or reactivate and use your device.

  Activation lock is activated automatically when you use find my iPhone on a device that uses iOS 7 or later. You can Configure find my iPhone from your Apple device.

  You can also take a look at this article on what to do if your device is lost or stolen:

  If your iPhone, iPad or iPod touch is lost or stolen

• How to turn on a wireless network card on a Satellite 3000 514 without hardware switch?

  I have a 3000-514 Satellite. This laptop has an internal mini PCI slot. Recently, I bought an Intel PRO/Wireless 2200BG wireless mini PCI card.

  The drivers have been installed correctly. The computer has detected the card and the condition of the equipment indicates that the device is functioning properly. However, a message appears indicating that the radio is turned off and must be turned on by the switch hardware. It seems not to be possible to activate the card without the switch...

  See the corresponding page in the Intel support:
  http://www.Intel.com/support/wireless/WLAN/sb/CS-020275.htm

  Now, the problem is that the laptop Satellite 3000 514 has quite such a material change.

  Does anyone have an idea what to do?

  Hello

  If the switch is not available then it of not possible to pass the card ;(
  It seems that the camera is not minPCI scalable WLan!

  In this case, he must use an external solution such as a USB WiFi key or card PCMCIA WLan

• limit switches will not turn off

  We use PXI NI Motion Assistant 1031 and measuring and Automation Explorer. Our limit switches always read assets, and when we enter the Configuration of the axis to try to change things, something creates a loop of update that prevents us from changing the default confiurations. Any suggestions on the problem of update or limit switch problems? The purpose of probing race shows good performance 0V - 4.8V / activate, so it is not the hardware.

  Thank you

  Aaron

  Has managed to solve this problem by reducing the pulling up of size of resistance (from 1 K 300) on limit switches themselves. Apparently, the motion controller (NI UMI-7774) requires a certain amount of current to power the LEDs position switch and save switches as active. Thank you, anyway.

  Best,

• Find the limits of a movieclip

  Version: Flash CS3, AS3
  
  Is there a way to find the limits (width and height) of a single movieclip image in a way that ignores white space around?
  
  That is to say. If a movieclip contains only a square of 10 x 10 in point 5.5 (in the movieclip), width and height is normally returned as 15 x 15. I want a way to have returned 10 x 10.
  
  Flash seems to have such limits - the chart displayed in the sidebar of library is set to that size. They are available only in AS3?
  
  Thank you
  Rick

  You mean transform.pixelBounds.

  Thanks kglad!

  See you soon

• Physical standby without ALTER DATABASE FORCE LOGGING

  Hello
  Is it possible to use the physics of the standby database without executing ALTER DATABASE FORCE LOGGING primary side?
  Can I use alter tablespace force logginng instead?
  
  I want to have a tablespace with nologging option to reduce the traffic of again for some operations.
  
  I can't verify this because I don't have enough servers to build the configuration of Eve.

  Were there any changes between 10g and 11g in necessity of doing ALTER DATABASE FORCE LOGGING?
  

  I see nothing in the documents, and I put them in place on both versions. In fact, my document Oracle 11 for DG of installation works perfectly in Oracle 10.

  I see nothing in the book of Larry to indicate a change.

  http://www.Amazon.com/Oracle-guard-Handbook-Osborne-Oracle/DP/0071621113

  If you are looking for B14239-05 and E10700-02 "Force Logging.

  You will find the exact text even under the exact same section 3.1.1.

  This highlights without change.

• Cannot find wireless networks - 'hardware radio switch off' on HP Pavilion dv6 Notebook PC

  The product name and number:

  HP Pavilion dv6 Notebook PC, product number: LZ802PA

  Operating system installed:

  Windows 7 Home Basic, 64-bit

  Error message:

  "Radio equipment extinguished."

  All changes to your system until the problem occurred:

  I was looking for a solution anywhere, including the hp Web site and forum and manual PDFs.

  I have a problem to connect to internet wireless (I can connect using a cable). The wireless button is on (seeing the key F12 is blue), but "Intel My WIFI utility" tells me that the "hardware radio switch off." I was looking for the switch on the case and sought a shortcut to do this - but could not find.

  As a result - my laptop cannot recognize any wireless connection, even if they exist for sure!

  I also used Microsoft System Restore to restore to an earlier date - before the problem accrued. There was no difference.

  Also, I reinstalled the drivers wireless Intel, Intel PROSet and my WIFI for Microsoft Windows 7. It does not help either.

  Help, please!

  I managed to fix it!

  I had to get into the BIOS and enable the network card in there!

• Low download speeds Internet Sophos UTM VM - but only the other virtual machines; Physical PC without issue

  So I have something very strange going on. I have a Dell custom host ISO on a Dell R310 ESX 5.5. My problem is that the Internet download is bad, but ONLY to other virtual machines. The Upload is normal physical computers.

  I currently have 4 virtual machines running:

  FreePBX, Win 2012 R2 Server, Sophos UTM (ISO VMware with the latest updates) and Win8.1 Ent.

  I have the following physical machines, I also used for testing:

  8.1 Win Office - wired

  Win portable 8.1 - wireless

  The lower test details, you can see on the image below.

  Iperf tests with 64 k window:
  Win Server 2012 to VM VM win 8 - 6.8Gbps <-VM VM good xfer
  Wireless Win 8.1 laptop to Win 2012 VM Server - 172Mbps <-VM to the well physical wireless
  Desktop 8.1 Win Win Server 2012 VM-619Mbps <-well wired VM
  
  Xfinity speed tests:
  Wireless laptop: 90Mbps down, 9Mbps place <-physical good Upload PC speed
  Wired Desktop laptop: 90Mbps down, 9Mbps place <-physical good Upload PC speed
  Win Server VM: 86Mbps down, place 0.6Mbps <-SLOW on VM!
  Win 8 VM: 90Mbps downwards, upwards 0.6Mbps <-SLOW on VM!
  
  As you can see in my tests, the only place the problem presented is VM to the internet. Physics to the internet works fine. My only thought is that there is something with the switch to the host or the MAC address.

  
  

  I don't think it's the Sophos Nic because it works very well from the physical to Sophos to Internet. I also have a ticket with Sophos Support; they look on the side of Sophos.
  

  Thoughts?

  

  I sent Wireshark packet capture of the Sophos support and they had this to say:

  This is to inform you of the issue, you face the slow, ask you please see attached screenshot of the capture of packets. We have found the package wth ECN (explicit congestion Notification) and CWR (Congestion window reduced on the VM machine, please get this checked with support of virtual machine or VM adapter. This happens when he fell over packages and the congestion window is reduced, that the issue is not with the UTM.

  In addition, indicator of Congestion window reduced (CWR) is defined by the host sender to indicate that it has received a segment TCP with the ECE flag set and that she had responded to the congestion control mechanism that indicates there is a congestion in the patch.

  So I did some research and the solution is to disable all options of unloading in the advanced settings of the NIC as shown in these two links:

  Cyber Explorer: Improved VM broadband network VM on an ESXi platform

  Disable offloading TCP in Windows Server 2012 | Knowledge Center | Rackspace Hosting

  This solved my problems. I now cross 9Mbps downloads on my VMs. hope this helps someone else!

• Looking for table of the physical limits on ESXi 4.1

  Hello

  I searched for some kind of table showing the difference between the editions ESXi 4.1.  But I always got the data from version 5 instead of 4!

  I am particularly interested to know the limit of memory for each virtual on ESXi 4.1 computer free and paid editions.  Well, my vSphere client tells me that my free license gives me 256 GB limit on the host hardware.  That's more than enough.  But what about memory for each virtual machine?  What limit?

  If someone is able to find this table, I appreciate it.

  TIA

  Ah, gotcha.

  Fortunately, vRAM payments do not exist in vSphere 4 in all. This goofiness is new in vSphere 5.

• Is find and replace - possible to find a page without instruction?

  Is it possible to search all my pages in a site and find out all the uneducated (for example without the word 'cats') is it possible to find and replace the functionality? for example to apply a negative?

• How can I find the limits of my FMS on bandwidth 4.5 license and the number of simultaneous connections?

  Adobe apparently felt that making this information difficult to find a way to do this is somehow a good idea.  I need to be able to determine exactly what version of FMS 4.5 license my business uses, and I need to see what are the limits of bandwidth and concurrent connections (RTMP and RTMFP).  How would I be able to find it?  Thank you!

  You are right: if return paragraph has also been formatted with this style of character, he wil appear in the found text. To stop GREP optional paragraph back, you can use

• find the memory leak when switching from Teststand object reference to vi

  I use Teststand to call labview vi and col ThisContext sequence to vi as object reference, but if I just completed this step and I can find the memory to help keep more, how can I avoid leaks memory inside the vi.

  See my vi, is displaying an interface message user.

  

  You should use a node reference close to close the references that you get after an invoke. In the code below, you should be able to close the references that you get the following:

  AsPropertyObject

  Thread

  Close these two references, once you're done with them.

  Also make sure you have turned off the collection of results of your sequence or you will use memory constantly to the results of the stage.

  Hope this helps,
