Order of movement OR 73xx, maximum speed

Hello!

Last time I was testing a new engine controller not. I discovered that when I put the gear 2000steps/s, the speed increases no more than 1968steps/s. I tried to put many configurations, but they do not work properly. I have to do some tests with a much higher speed than 2000steps/s... Could you tell me what I did wrong?

Simple program was created in Labview 2011

Vision and movement of pilots-> NIMotion830

Map of NOR -> NOR-7334

Universal movement - UMI-7764 interface

Windows XP

I tried to affect the speed of the motor in open loop stepper.

Thanks in advance

Kind regards

I found the solution.

The problem was too small value of acceleration/deceleration. If the program realizes that speed rise time will be longer than 8, 196ms, it will stop increasing the speed lower than the requested value. I have no idea why, but perhaps it is caused by an internal counter that handles speeds method.

After I increased the value of the block of accel/break, exit to step easily reached a desired frequency.

I close the topic.

  • IdeaPad S205 RAM/memory: maximum speed?

    Hello

    Lenovo customer service/tech support I asked this question several times, each to give me an answer to 1066 mhz.

    What is the maximum SPEED for the RAM/memory usable by the S205 with AMD Fusion the E450 processor?

    I understand 8G (2 slots of 4G) is the maximum capacity of ram.

    But what is the maximum speed of the ram? I thought that the maximum allowance is 1 066 mhz due to the site, despite the AMD website, saying that the E450 can manage 1333 mhz.

    Obviously, I want to max out my RAM. I went on the site of Kingston and used the option to locate specific RAM for this device and it gave rise to 1 066 mhz 2X4G sticks. So I bought and it just. I just want to come here and see if someone actually KNOWS what as the maximum speed capability (or anything else I should be aware of outside Gig capacity) which can take the S205 with AMD Fusion the E450.

    EDIT:
    In new research, I found the following.

    (1) according to the support of crucial technology, the RAM frequency/speed is controlled by the processor CPU only. And as said by him, the AMD 300 and 350 have a maximum speed of control for the RAM of 1066 mhz. However the E450 has a 'controller memory integrated (up to 1333 MHz) DDR3"as seen go ( http://www.lenovo.com/shop/americas/content/pdf/system_data/s205_tech_specs.pdf ).

    Also note that just below him, he goes on to say that the maximum speed for RAM is at 1066 mhz. Therefore, this disturbs more the issue. It seems to me that, when they are max memory capacity and speed, they forgot that the E450 can manage more of the E300 and E350 and simply serve their maximum speed of 1066.

    I already went ahead and bought 2X4G 1066 RAM. Fortunately, I did not open them. But now it comes to ship to the company and having to order the good 1333 mhz RAM. Otherwise I use RAM that is slower than my full potential.

    I advanced and called Lenovo and it brought to their attention. After the daughter of back and forth between 1066 and 1333, she decided at the end (of course assistance from their technical support level 2) 1333 is maximum for E450.

    Conclusion:
    It seems that if you have E450, you may have to 1333.

    If you have E300 or 350, you can have 1066.

    If anyone has confirmation, please tell.

    If you go to the Lenovo support site and enter the serial number of your S205, if will give you a list of all the machine components (including the RAM module manufacturer, size, speed, etc.).

    The manual indicates that the specification of RAM for my S205 1066.  By entering my serial number, I found that Lenovo had actually installed 1333 RAM in my system.  Then, when I added more RAM, I knew to add 1333 instead of 1066.

    No, I didn't bother to check my actual speed of the RAM.

  • Satego X 200 - 21U - after Eve: fan at maximum speed

    Hello

    I have a Toshiba Satego x 200 - 21u.
    I often use the mode "Eve". I close the screen with a wink, and the next day I still.
    Sometimes the fan goes crazy. It runs with maximum speed, as if it was too hot.
    When I stopped (no restart) and turn it on again, everything is fine.

    Is there a problem with a driver?
    Is it lack of Microsoft?
    Or is it really too hot? Y at - it a tool that shows me the temperatures?

    Thx for reading!

    Good day

    You close the Notepad application with open or closed?
    This occurs if you close all applications before you use mode 'sleep'?

    When you write sometimes it is not easy to say why this is happening.
    Do some tests and try to find out when this happen.

  • Envy TouchSmart 17-j153cl: maximum speed DDR3L RAM in HP ENVY 17-j153cl

    Hello!

    I currently have the Touchsmart from HP Envy 17-j153cl with a BIOS updated. The vehicle has currently 2x8GB sticks of RAM SoDIMM DDR3L strips - 1600 MHz. I was wondering what was the maximum speed of RAM supported by the BIOS. I'm hoping to upgrade to Kingston HyperX 2133 MHz SODIMM 2x8GB DDR3L, but I heard that if the laptop BIOS does not support the higher speed, it is just downclocked. So, I wanted to know if bios default HP on the 17 - j153cl can handle the speed of the potentially new RAM. Thank you for your help.

    Sincerely,

    Hello

    1. This permanently cancels the warranty. Are you sure that the machine allows to do this?
    2. I have some older posts to talk about RAM. I usually use the car for example. You can run a race car at high speed on a race track, not on normal/streets roads; especially on roads with speed limits.

  • Maximum speed of read/write taken supported Sony Xperia Z2 for MicroSD cards

    I am looking to buy a microSD for my Xperia Z2 phone (6503). My question is: how fast it can write data to an SD card. For all I know, these speeds are dependent on the controller of the SD card. If I'll know it approximate numbers I can acquire an adequate microSD card. Right now I'm trying to decide between: SanDisk SDSDQX - 064 G-U46A Extreme Plus 64 GB - 80 MB / s GB SanDisk SDSDQUA - 128 G-G46A 128 Ultra - 30 MB/s write for these microSD cards speeds half accelerated indicated reed are numbers. I like 128 GB Ultra card capacity, but would not hesitate to buy faster 64 GB card of more extreme.

    If you use 4K as recording features, you may need to get a high speed SD! (go to the Maximum speed you can)

    So I think that like extreme would be preferable in this case, but if your phone is what use you (like me) the maximum capacity (which has better speed as well, if not useless) I use a class 10 128 Go!

    Like many, I know, I think that same 30 MBP will be sufficient for a 4K video!

  • Download/Download blackBerry Smartphones Maximum speeds?

    I have a BB 9700 "BOLD". I was testing the speed of data transfer using an app called "NetWorkSpeed" on the app store. No matter how fast my network connection has been, it seemed that the bold has been capped at a maximum speed of about 250 Kbps, two additions or downloads. It's using a 3G connection, or my house Wi-Fi. My House Wi-Fi should be able to make downloads of 6000 Kbps and 800 Kbps post; but the "BOLD" has never led neighbors of those. Now, it is a test of speed that is done only to the device, not a captive computer or something like that. A captive computer seems to be able to transfer more quickly through the "BOLD", "BOLD" can transfer to himself. Is this a real limitation with the "BOLD", or something else going on here?

    BTW, I connected my PC to my "BOLD", use the "BOLD" as its modem, and I could get 1.9 Mbit/s/330 Kbps with it. Not as fast as my home Wi-Fi, but respectable. But much, much faster than the Blackberry can transfer to himself.

    Due to the complexity of the entire network of BlackBerry service, and how it works through RIM servers, make it difficult to calculate the speed of transfer. Unlike all other phones, all data from one blackberry phone go directly to RIM servers, then to where she was originally meant to go. So to reduce the amount of data, RIM is approaching the excess data, which are used by speedtests to calculate speed. This results in low transfer rate calculations.

    The 3G speed is based on the network.
    The speed that show you are much lower than they should be. He speedtests lots are not available for BlackBerry phones. I remember using 1 Web site specially designed to calculate rates for blackberry phones and it capped download speeds to 500 for everyone over 3 G, but on wifi, it showed almost 80% equal to what was the broadband speed.

    I'll try looking for this link.

    RIM: Research In Motion, the company that makes BlackBerry.

    I hope this helps.

  • How do you get the tweens to move at a constant speed?

    I have Adobe Flash CS 5 and you had problems trying to get a Tween created to move at a constant speed. I was converting a graphic I created a symbol and make a motion tween, however I only understood how to move the interpolation on an image by image basis. Is there a way I can trace the complete track of interpolation and set it then travel along this path at a constant speed, and not which move from one point to another in a number of executives? The goal is a green circle that will bounce off the edges of the window/computer screen as it moves at a constant speed in the appropriate direction. I am a novice in flash and have been fiddling with the program for a few days so that any help would be greatly appreciated. Thank you!

    you are the object of the movement rate will depend on the number of images in which it moves and your main swf frame rate.

    If you want an interpolation is not Timeline/frame number of dependent, use actionscript to interpolate your object.

  • Why my PC fans turn at maximum speed all the time?

    I have a (new)< 3="" months)="" hp="" pavillion="" p7-1449.="" the="" fans="" (case+cpu)="" tend="" to="" run="" very="" fast="" (load)="" until="" i="" restart="" the="" pc,="" and="" hit="" esc="" for="" boot="" options.="" i="" usually="" enter="" the="" bios="" screen="" and="" exit="" without="" changing="" anything="" (by="" this="" time="" the="" fans="" slow="" to="" less="" than="" 1000="" rpms="" each) ="" and="" the="" pc="" boots="" up="" with="" the="" fans="" at="" the="" lower="" speed.="" the="" fans="" stay="" low="" until="" the="" load="">

    I hear fans ramping down when I do and reported by the BIOS fan status seems to support my theory that the fans really slow. Unfortunately, I do not yet have equipment controlling software installed on my PC so I don't see no confirmation of the fan speeds up when running in Windows 8. [HP has none of these tools?]

    If I stop and restart Windows 8 normally (so that it uses its startup optimizations 'fast'), then fans seem to go for the maximum RPM.

    The machine was purchase in Nov 2012: apparently not the internal dust is the problem and it would be not fixed by forcing a boot cold. I suspect that it is a software problem (I consider the offending software if it does not reset the hardware correctly at startup).

    It seems that the fans turn upward but never slow down: is it possible to fix this? I wish that the machine to shut up when it isn't loaded (without having to reboot to get it that way). Otherwise, there is no performance or stability problems (yay).

    Hello..
    This seems to be the problem with your bios on the desktop.
    Discover the same fan speed if you have only the keyboard, mouse and the power cord is connected.
    Also check out an update of the bios on the desktop.
    This would probably solve the problem.
    You have a bios update available on the HP Web site.

  • HP 8560w: CPU clock stuck at maximum speed

    I am under W7 Pro 64 bit on an HP Elitebook 8560w, with i7 2820QM. Yesterday after installing a new device (external finger scanner), I noticed that the fan is running too high. I checked the CPU usage, it has been very low: up to 5%. The processor clock, however, remained at its maximum all the time. I thought - there is a problem with the device driver that is the cause. So I deleted the device in Device Manager, also checked the box to remove the software from the device. No change - problem still there. I've used windows restore for the restoration of control point before the installation of the device. Still not good.

    Then I searched the web for similar problems, could not really find anything very close to my problem. There were some suggestions to update the BIOS, which I did and it did not help. When I let the CPU to 100% its maximum clock, it works in 3.1 GHz (CPU - Z) and the temperature is 88 degrees celsius at rest (ouch!). I turned down in the power settings to work 75% maximum, which turns to ~1.6GHz and then the temperature is not so dangerous, that the fan is now not so much.

    I found some tips to use msconfig, try the boot, which also did not help, but then I tried to disable all the services (in msconfig) and see if that helps. Long story short, if I let all services enabled except 'Power', my CPU running at 3.1 to 3.4 GHz (still not as low as I hope), but at least it is not blocked at speed. And - most importantly - the temperature of the CPU is a reasonable 53 - 58, despite the high clock frequency.

    So here's my question - any idea what could be wrong with my laptop? Why is it still ongoing at a higher clock speed? I have another machine, a desktop computer with i7 2600 and who works 50% clock most of the time, is that max under a higher load.

    Yes, I solved it.

    The problem was inside the app to scan finger. She defined the level of CPU power to maximum during the initialization of the external finger scanner (to avoid possible problems with bandwidth USB) and it should unset it is. Unfortunatelly the endpoint does not work in my case and the level of CPU power remained on the maximum level. Problem has been resolved by application of the small command line (SetCpuPowerLevel) provided by the supplier of the application, which has the power to the processor level back to default.

  • Not running at the maximum speed

    Hello

    My profile for my computer notebook (Acer Aspire v5 - 552 G) says that my processor speed is clocked at 3, 5 GHz, how ever all the measures that I took, it wornt spend 2.9 GHz.

    No idea what this may be due?

    The processor is a Dual Core of A6 - 5357M (with Turbo Core technology)

    The speed of the A6 - 5357M is 2.9 with a core of 3.5 Turbo. The Turbo is automatic. Turbo Core is much more conservative than the Turbo Boost. Intel Turbo Boost just said: ' OK, I'm going to jack of your processor for maximum then scale (maybe) your processor is backward in time.» On the other hand, AMD Turbo Core constantly varies your CPU giving you average moderate boost.

  • T500 operating at maximum speed

    My t500 runs at full speed or a little more at 2926 mhz acording to AIDA64 while on battery. This makes the laptop run hot and battery life. I have reset the BIOs to maximize independence and then set as default. I even removed the battery cmos for a few hours and it will still not reverse this speed. The time sometimes run up to 85 degrees C. Now the Task Manager shows 0 to 15% with the use of less than 2 GB memory usage. It should be run at approximately 800 mhz on battery. That's what my wife T500 then runs only on battery. They both have 9 batteries.

    I see two options to try:

    1. check your BIOS version

    2 - power Manager installed?

    You can do the installation and execution Lenovo System Update

  • Where can I find the maximum speed and size for a 2000 HP RAM memory

    I looked at the stick of 4GB that comes with it and she has this information on it.

    MT16KTF51264HZ - 1G6M

    4 GB 2RXB PC3L-12800-11-11-7 P

    I would like to know what exact memory to get and how much can be set which is actually useful.  As it is now, it's quite slow.

    Simply duplicate this module you have. At the moment no HP laptop consumer cannot accept any faster than this alias DDR3-1600 PC3-12800 memory.

    Quote of repair:

    Supports up to 8192 GB of RAM.

    Up to 8 GB is the maximum. An SSD would be on the upgrade of the only possible performance. On AMD models, the CPU is soldered to the motherboard, so you can't upgrade that. With the processor AMD E1, I am skeptical even with 8 GB of RAM and an SSD, you have a usable computer, frankly.

  • Maximum speed and the amount of RAM for m7664x

    I have a m7664x that I will be upgrading to Windows 7 64 bit and I want to upgrade the RAM.

    According to the specifications of the product, there the mother of A8M2N-(NodusM3) with 4 DIMMS.  On this page, it says that it supports up to 4 GB of RAM to 667 MHz.

    Now, I came across a few posts here and elsewhere that suggest it can handle more (up to 8 GB) and more RAM speeds (PC6400 / 800 MHz) and recognized him and used.

    Can anyone confirm that it can support up to 8 GB of RAM and with higher speeds?

    Wow, what an old thread!

    To answer your question and update this thread, I bit the bullet and bought 8 GB of 800 MHz RAM and worked for almost a year now.  I seem to remember that I ran MemTest on it and it shows that he is indeed running at 800 MHz, but that's a long time I would have done, if I did.

    I also thought about upgrading the processor, but already at that time, I installed the RAM (close to a year ago), compatible processors were hard to find and expensive.  In addition, the machine was not used for anything else than to the General functions and has also been hampered by graphics shipped to start.  At the end of the day, spend the extra money on a pretty old computer RAM was the limit for me.

    blueeclipse86, you can try to upgrade the RAM on your machine, as I have done, but, of course, I can't guarantee that it'll work for you.
