• 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.

• 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.

  My problem is that there is no synchronization between the picture and sound (+ the sound is thin about 5 seconds +)
  When I watch TV on Windows Media Center on the Qosmio G50 - 10I

  I tried to change the settings in Windows Media Center, but some will escape.

  How to connect this TV to the G50?
  You use the HDMI cable that provides audio and video signal together at the same time or you connect the TV with two different cables (for audio & video signal)?

  Also check the settings in Realtek HD audio Manager located in the control panel. Here, you can change some sound effects for different outputs (digital speakers, HDMI) audio

• 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.

• Control and Simulation in a loop / while loop with TCP/IP reading / writing of synchronization

  Hello, I have a problem with reading TCP/IP and written in two loops. The problem is NOT to get the two loops to read and write to and from the other. This has been accomplished. My problem is when I run control and the loop simulation on my laptop and the while on a RTOS remote on the controller on-Board of LabVIEW in a remote PXI chassis, the while loop the remote system running on four 4 times faster than the loop control and simulation on my laptop. In other words, for each iteration of the loop control and simulation on my laptop, there are 4 four iterations of the while loop on the remote system. I need to know how to get a degree of kinship (1:1) with these iterations of the loop. When I run a longer simulation in real time, say 10 seconds, the control and Simulation loop begins to slow, i.e. the simulation time slows down until it is no longer in real time and the "Late Finish"? Parameter is set to true and the LED lights and continues to stay lit. At this point, the system destabilizes due to what I believe is being well sampling rate too discreet and I have to end the simulation. How can I get a ratio of one to one between the loops and also to avoid slowing the loops causing destabilization?

  To give an overview of my application, I implement a control system in a network, seen in "image2.png". This is achieved using my laptop as a subsystem 1. Reference signals are generated from the laptop and the error signal is produced. Control measures taken and the control signals are sent via TCP/IP to the remote system. Position feedback is returned, and the process repeats. My system has Core I7 Procs w / 3 GB of RAM, up to 1 GB/s speed via ethernet and LabVIEW 2011 installed with all necessary modules and networking tools. The attached VI Custom_Wireless_Controller works on my laptop. The remote system I'm working on that has the 7830 NI R Series with FPGA card. OTN runs on the PXI chassis with an enbedded controller that has networking capabilities of up to 100 MB/s via ethernet. I use the FPGA for the acquisition of data and apply control signals to my plant. The plant is the PCE twist connected to the FPGA through the cable of the ECP - RIO of NOR. Subsystem 2 is this side of the CNE. The FPGA collects position, he sends to the controller via the network, receives signals from the network drive and writes signals to the plant power amplifier that operates the plant. This process is repeated and the VI and is titled Custom_Wireless_Plant.

  I appreciate the help really and look forward for her and for any question!

  Well, the first step is to understand what you have set up right now. Your control and Simulation loop on the side of the controller is configured as 'Runga Kutta 4' and you have a loop timed on the other side. In addition, you have the primitives of TCP/IP on the control and the Simulation diagram and means he will perform (a message) on the size of each minor step, which in your case is 4.

  So, you have two options:

  1. replace the Solver side controller Runga Kutta 1 (this must synchronize loops)

  2. hold RK 4, but create a Subvi around two primitives of TCP/IP and configure from the VI to run than the major (continuous) step-size. If you do it right, you should see a 'C' on the upper right part of the VI you have created.

  Please let me know if what I said is not clear...

• Music and sounds are coming through too fast and too sharp.

  Music and sounds are coming in my treble speakers too much and too fast. Looks like Alvin and the chipmunks. It happens on all sounds from a CD or the Internet. All diagnostics check out OK. It's Windows XP. Any ideas how to adjust the sound quality?

  Hello Jcbrewer,

  Thank you for your message.  Take a look at the information below which I copied from http://www.microsoft.com/windows/windowsmedia/knowledgecenter/mediaadvice/0067.mspx.
  Why my music sounds like chipmunks sing?

  Don't worry, little domestic rodents in Windows Media Player is not configured. Instead, the clock of your soundcard probably has a timing problem. To resolve this issue, try to reduce the level of hardware acceleration for your sound card by following these steps:

  1.	In Control Panel, open sounds and Audio devices.
  2.	In the Volume , in the settings area of the speaker tab, click the Advanced button.
  3.	In the Advanced Audio properties dialog box, click the performance tab and adjust the hardware acceleration slider to adjust the calendar clock for your sound card.

  Remember that, if your sound card supports multi-channel (5.1) audio playback, turn off hardware acceleration (moving the cursor of None) will cause the sound card to play all the audio multichannel stereo (two speakers).

  If you can't solve the problem by adjusting hardware acceleration, you can check with the computer manufacturer for an updated audio driver.

  Another possibility is that it could be a joke any.  You can perform a clean boot that will start the computer without programs 3rd party.  The steps are below:

  1. Click Startand then click run.
  2. Type msconfig in the Open box, and then click OK.
  3. On the general tab, click Selective startup.
  4. Under Selective startup, clear the following check boxes:
     • SYSTEM process. INI file
     • Process of VICTORY. INI file
     • Load Startup items
  5. Click the Services tab, select the hide all Microsoft Services check box, and then click disable all.
  6. Click OK.
  7. When you are prompted, click restart.
  8. After the computer starts, start the program or game and see if the problem is resolved.

  If the problem is resolved, you can check in Add/Remove programs to see if there are any suspicious software that needs to be removed.  You can also check your startup programs in MSCONFIG.  To access msconfig, click on 'Start' > select "Run" > Type msconfig in the box and click on enter.  You will see the Startup tab, you can check all suspicious programs start at startup and remove them.

  See you soon

• 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?

• Graphics and sound early are nervous on HP Pavilion

  Hey, first time posting here and hoping someone can help me with the questions I've had with my laptop. Here is the Basic for my laptop specifications:

  HP Pavilion dv6-3150us

  Windows 7 Enterprise 32-bit Edition *.

  Intel Core i5 CPU 2.53 GHz M 460

  4 GB of RAM installed (2.43 GB usable)

  Intel HD Graphics

  Video memory up to 1696 MB

  TOSHIBA 500 GB hard drive *.

  Dolby Advanced Audio with Altec Lansing speakers

  At rest approximately 800 MB RAM usage

  * changed after the drive started failing, in other words not original hardware/software

  So I got my laptop nearly 3 years ago, things were pretty amazing with my laptop and it is honestly the best (and first and only) laptop that I'm away until now. In any case, after 1 year and 2 months, or so 650 GB hard originally started failing. Coincidentially the year 1 mandate had expired, so obviously the call center of HP did not help me at all. Ultimately I had to get a replacement from the hard drive and get my school technician to do the job of its installation and recovery of my information to recurring. Of course, by doing so the original laptop Windows 7 Home Premium 64 - bit OS drivers and all were lost in the old hard drive, so it has installed its own version of 32-bit in my laptop and did the best he could to download and recover drivers and functions of the laptop. Ultimately all this turned out pretty well with the exception that the wireless is not connect more (in any case it is not the real problem, I am here to ask questions on)

  Lately I had problems related mainly to the audio and sound. Everytime I play a video (either from a DVD, hard disk or streaming online) the video begins to become unstable and slower with the time that the video is almost completely stopped. This change in the video also affects the speed at which the laptop running, making it's slower and sometimes I have to either close the video program I use to avoid phone freeze completely.

  A similar thing happens whenever I'm playing games. The graphics in the game are slowed down gradually, and the sound is also affected by the whole process, makes them nervous and slower. This product even when I put the games in lower graphics levels there are (by the way, the games in question are GTA San Andreas, the Sims 3 and DC Universe Online) the problem got worse with time and appeared older 3 months back or almost. Also, it happens randomly. Moreover, indeed like laptop computers HP the more out there, mine has always had problems with ventilation and dust in the fans so it is usually very hot and I would not be surprised if it was any problem where the roots of.

  So far I have removed the unnecessary startup with the Task Manager process, scanned the laptop together with AVAST and Malwarebytes, removed programs that are unnecessary, / that I don't use, files cleaned and defraged the drive hard, has ran memory diagnostics, updated audio and video players, updated the BIOS and the problem still remains.

  My best guess would be that the sound cards and video begin to fail or, even worse, that the motherboard is the one to blame (or simply conflict pilot/codec), but I have tried so many different things and visited so many different forums that I don't really know what it is. I hope someone can help me with determine what is wrong and the steps to resolve this.

  Thanks in advance.

  Thanks for your advice and sorry for the late reply. I tried your suggestion of analysis system for missing/conflicting drivers with the HP Wizard, but there was no change, that this is reading once I uninstalled and reinstalled video driver (which would have been the main reason for my question)

  In fact, I just got the HP Support help in Twitter, and in the end it turns out that my problem with unstable video is not software related, but it might be in fact that my laptop motherboard reached its peak (due to overheating and eternal ventilation). Thank you nevertheless for the help and advice to get the recovery disc for my computer (should have that before, but now at the end)

  Thank you very much!
