Haptic motor problems

• PID motor problems

  Im having trouble with an application of linear motor control.  I'm using a servo-motor/converter to power a linear drive.   The player is running in current/torque mode so that the output power/force is proportional to an analog input that is sent to him (no setting parameters).  For this particular application, Im using the express vi 'set up fake signal' to create a waveform of sin that is used as the target value then inturn helps determine the voltage sent to the engine and thus, out of power.  The tension of a load cell is then read through PCI-6014 and convetered at a level that can be compared with the output of analag, scale factor for the torque mode.  There is also a PCI-6601 used to determine the position, but should not be relevant here.

  Without PID.     Using a load cell, I see that the wave of fishing is truncated at the top and bottom, it rises to fast in response to the tension and then from the trays.  The reverse happens when unloading and it reaches a low load to soon and there is also the truncation. I will attach a figure which can demonate the problem better than I can explain it.

  

  Without PID.   This isn't a saturation effect, but as I can raise the amplitude of the input voltage and the force will follow the same type of waveform, but again the load levels.   Ill. attach a screenshot 2 new levels of load of 2000lbs.

  

  I can look at the levels of current/voltage output of the command servo which feed the linear actuator and that they are the sinusoids perfect, after all what is the input voltage, if guided by PID or not, its a mirror right, without truncation as occurs in the above figures.   There is also no problem of speed or acceleration, it is well under the speed limit, that this system can work, IE under 0.25htz and it can run 50htz to these displamcements.  So, these are not the problems.

  As I understand it, the PID is commonly used to correct this type of problem and is standard with machines that need to produce force in this way...  Infact, I learned from the people who make the drive I use to fix this type of problem.   Yet, Im could not get it to work. I tried to change the P term accoring to the N? I have the document below and dosent seems to correct the loss of crete, so Im doubtful the I terms or D will do much (and have tried without success). I'll attach a third screenshot and link in the general guide for the PID below

  with the PID, with P increases so some departures of instability

  

  Ive tried reinstallilng labview on a different computer, with PID and get identical results.

  I'll join the code I help him, not that I'm waiting for anyone to find, its big enough.

  Any help is greatly appreciated.

  Jimmy,

  If your control loop does not work with a deterministic timing, the highest rates of change of the setpoint to the situation, so the quality of the control loop also limits the frequency of your sinuses. However, the loop itself is always on to 2 kHz, so the loop time and jitter of the same order of magnitude, then it will be very difficult to get a system of stable control with this configuration. Reduction in the rate of control loop is also not a solution, because the linear motors are very dynamic systems, requiring control loop series kHz.

  To improve the situation with your current setup, you can always try to better structure your vi, delete dynamic memory allocations and so forth, but the improvements will be very limited. In fact, there is a reason why NEITHER a lot of success with products such as LabVIEW RT or compactRIO and the reason is the deterministic behavior of these platforms that is required by the dynamic closed-loop control applications.

  To answer your question on the amplitudes: regulator PID tried to generate an output signal, which translates as the set value - PV = 0. So for example, if your load cell outputs 0.5 V/N and you want to generate a force of 10 N, the set point must be set to 5. In other words, the scales of the setpoint and the PV must match, but this does not mean, you must necessarily across the PV before you go to the PID controller. Instead you might evolve set points to map to the copying. The advantage of this approach is the fact that you don't have to do calculations online on the feedback signal, because you could precalculate a set value table before you start the move. This approach would calculate you your calibration data in the matrix of setpoint values.

  If you follow this method, you might also think of using a control chart of standard movement as a PCI-7352. This Council deals with all onboard, real-time control tasks so no LabVIEW RT is necessary and you can move the locker bays precalculated in the memory of the Commission (contouring mode).

  I hope that gives you some ideas how to proceed from here.

  Kind regards

• iPhone 7 creation of a circuit when on a dock

  Here's a weird one for you...

  I just got my iPhone 7, and everything of fine. What is strange is that when he's on the dock (one official apple) and connected to a power supply, the back of the phone vibrates as I slide a finger or fingers (I tried with 3) top. This does not reach the screen and doesn't happen if I also touch the metal casing with a finger of the other hand at the same time. I guess I'm creating a circuit which is triggering the haptic motor which works only when it is connected to the power? It's strange. I even if it was defective at first, thinking he was going to vibrate a little all the time is on the dock, but realized that happens when I touch and move my fingers softly through the body.

  Can any who else reproduce it, or is mine just special?

  It's something because he does, if I touch it with both hands, to complete the circuit, and it only when not connected to the electric/static.

  Just it takes off from the wharf, used another socket, USB plug and cable lighting. Put the phone on the couch face and ran my finger on it... doing the same thing! My wife came in one I tried. Done here also. I touch it with his index finger on his left hand and run his right index finger to the back, and he has ceased to be. Once she took her left index finger he started to do it again.

  The vibration feels stronger at the top of the phone.

  We had Antennagate, now Vibratorgate! Laughing out loud

• Hello! Someone has some problem with the haptic on Macbook 12 "2016 function? It does not work on my Mackbook.

  I'm trying to figure if someone has my problem with the haptic on Macbook 12 "2016 function. The option is checked in the preferences system, but it does not work.

  Thank you

  Hello luigi10m,

  Thanks for posting on the Community Support from Apple. From your post, it looks like your haptic feedback does not work when you click using your trackpad and the setting is enabled. I know that this is a great feature and it is important to make it work. I'll be happy to help you.

  First of all, I would like to assure you that in system preferences > Trackpad > clicking silencer is not checked, that might help. In addition, it would be useful to reset the settings of the SCM. You can find instructions here: reset the management system (SCM) controller on your Mac - Apple Support

  I'll also include those for you here:

  1. Stop the Mac.
  2. Plug the MagSafe or USB - C adapter to a power source and to your Mac.
  3. Use the built-in keyboard, press shift-control-Option on the left side of the keyboard, then press the power button at the same time.
  4. All the keys to unlock, then press the power button to turn on your Mac

  Take care!

• Problems with encoder motor switching noise readings

  Hi all

  I wanted to ask advice with a hardware problem which seems to be pretty common.

  Here I describe my request:

  We are controlling an electric actuator for robotics application. We use encoders to take position readings, and we need to perform analog acquisition for other measures (for example, the force measured using strain gauges).

  The problem is:

  In summary, I have problems to properly acquire position readings of a linear encoders quadrature and also a few analog inputs. The cause is the switching noise generated by the drive motor that we use (which is an engine without Stricker of CC Moog BN-23-23).

  Our acquisition platform is an NI PXI-8106 with a PXI-1042 q chassis. We have two possibilities to acquire the signals. We have a multifunction DAQ series NI PXI-6259 M and a FlexRIO NI PXI-7951R with one module DIO NI PXI-6581R.

  The switching noise have a frequency of 30 kHz. In a scope, we see a series of peaks of noise which are present only during a short period of time (approximately 1/10th of the duration of the noise). The rest of the time the noise is not present.

  The Accelnet amplification module that powers the electric motor gives us a clock signal synchronized with the noise (whose frequency is approximately 1/4 frequency noise). This clock signal provides a way to solve the problem of analog acquisition. We can use this clock to make an acquisition stamped with an external clock in LabView connecting the clock on a spit of PFI or FPGA card. But the noise is also corrupt this clock signal (we get an error daqmx us warning of possible defects in the clock signal and also to stop the acquisition). I believe that to solve the problem of encoder we can also solve the problem of the analog acquisition.

  In the encoder readings noise makes our County to counter upward or backward gradually fast enough. We can get an increase in the position of about 10 cm per second with no appreciable movement in the linear actuator.

  It would be a great help if someone could put the solution he uses to solve this problem.

  Thanks in advance for your help,

  jespestana

  PS: I stress my conviction that we have a hardware problem, because we have only bad readings when the electric motor does not work. I am therefore convinced because we have already done reading encoder and analog with the help of other players, such as hydraulic cylinders. So, I think that it is not a problem with our software (of our LabView VI).

  Hi jespestana,

  I don't know why the noise could be the cause of your encoder can increase more slowly...  However I have a suggestion on the map of the M series (6259):

  M-series cards have a digital filter integrated on the lines of the PFI (see the user manual of M series).  Looks like the noise is a series of 3 ~ US of impulses (1/10 to 1/30 kHz).  Of the available filtering frequencies that you can set on your M series is 6,425 US, which must ignore the impulses (high or low) that are less than 6,425 US. You can configure the digital filtering with a property node DAQmx:

  

  One caveat is that the driver only allows you to configure the digital filtering for entries counter on M Series devices.  For example, you can use a digital filtering directly on your task of encoder, but not for your sample clock HAVE.  A workaround can be found here, which is to set up a dummy counter job to define the PFI filter for your task to HAVE.  If you use the same PFI line for your encoder and the task to HAVE it, you should be able to just set up the PFI filter through the task of the encoder and worry for the workaround.

  Regarding the RIO Flex, I think that you could implement something similar on the FPGA, but I'm probably not the best person to comment on this subject.  It would be probably a lot more work to use the DAQmx API's built-in filtering.

  Best regards

• Problems when you try to move the 3 stepper motors

  Hello

  I have problems when I Isaiah to compile a 3 stepper motors control program.

  I have 3 steepest motors and controller (3 SMCP33 + SMCP33-EVA) nanotec.com, they also provide an example of Vi to control a motor that works successfully, but problems happen when I try to adapt the program to try to start the 3 Motors. The final application for this is going to be a Cartesian robot XYZ so finally I need to program coordinates to move the 3 Motors.

  I am new to LabVIEW, so what I do is try to adapt the nanotec example to order 3 engine as follows.

  -J' I assign each engine a different address, doing so that I can run each engine separately. But when I try to run 3 programs at the same time, they work but all moving them the engine (the first that has been run).

  -If I try to make a sort of sub - VI is the same thing, only one motor is driven.

  -Moreover, I get a warning when I try this, I have attached a screenshot of this.

  I have attached the Vi and texture it to improve my description.

  I woul be grateful if someona can help aport.

  Kind regards.

  Thanks for posting the original.  By comparing the two screws immediately gives an indication of what might happen.

  In the picture you posted you circled two places where you changed the address of the reader. In the Example.vi - Nanotec address of the player is connected to about 14 seats.  So when you try to run the other engines in your modified program, the 12 places, you have not changed the address of the player are always preset to motor 1.

  What you need to do is to divide the example VI in at least three parts.  The first part initialization. The next part moves the engine.  The last part ensures that the engine is stopped and made any required another stop.  Each party becomse a separate Subvi. Each Subvi has the address of the reader as input.  The initialization and shutdown parts are placed before and after a while loop.  The movement parts are inside the loop.  You can use three of each sub - VI for the three engines or a Subvi combined with subVIs move three to manage all three engines.

  I can't say what approach might be better without knowing more about how you plan to order the engines - one at a time or all three at the same time, what kind of feedback is used, how management mistakes and other topics.

• PROBLEM VIBRATION MOTOR SE IPHONE

  I bought the IPhone SE of Sahiwal Pakistan from an importer. Here is not official Apple store in Pakistan. Guarantee of the iPhone WILL be completed in April 2017. It has a problem that its engine vibration car on and it starts the earthquakes. I have reset several times but it was not fixed. I have send an email to apple, but they may not answer. Where can I make a complaint about this problem. I have all the notification about the vibrations but the problem is still off. Please help me.

• Bad rotation with Newport PR50PP Platinum rotation controlled by SMC100PP motor controller - is that a communication or a hardware problem?

  Hello world

  It is a long shot, but I can explain my problem and I hope that someone has seen this problem before.

  PROBLEM:

  I use a rotation of Newport PR50PP turntable that is controlled by a motorcontroller SMC100PP through LabVIEW. In my experience, I shoot the scene 180 degrees to the right in increments of 36 and then turn to "zero" counterclockwise. This "zero" point must be the same 'zero', I started to leave before the rotation. The problem is that it is off by nearly a whole degree. I need to always start in the same place.

  The big problem - computer / Platinum rotation it's originally 'zero '. I record the unit of internal rotation of the scene after each movement and he tells me it's the same 0.00 that began.

  Q: is this a problem of communication between LabVIEW and the PR50PP or a mechanical problem?

  OTHER NOTES:

  • The change of rotation is repetitive and linear. I repeated more than 15 times and got about the same offset.
  • How I discovered this problem - I have a half plate on the rotation stage and looked between cross polarizers. I recorded the Cos ^ 2 model of intensity of each scan. Each pattern is rotated to the front even if the computer reports that they should be at the same position.
  • I'm under LabVIEW 2011 and by using the controls provided by Newport SMC. They communicate via USB of series.
  • Joined a technical description of the problem that my labmate written upward.

  Any idea is appreciated.

  ~ Liz Cloos

  Hello world

  After running additional tests, I discovered that it is NOT a problem of LabVIEW. The plate wave inside the rotation of PR50PP plate was a little loose and gave the appearance that the zero is changing. The ribbed plate kept turning slightly after each change of direction.

  Thanks for trying to help.

• Problems with iPhone 7 Plus the 'home' button?

  Today, I stopped at a store and looked at the time of 7 more for the first iPhone. I was curious about the new home of the haptic button.

  I didn't feel a thing well. I thought there might be a setting and so I asked a salesperson. He said he "thought" he could feel a bit and had me try things like closing an application and return to the home screen. But no matter how gently or strongly I pressed the home button, nothing happened. Once opened Siri, but then I couldn't close it.

  He couldn't have worked either do.

  So, while I admit that my "sampling" is small, with 100% of all so far the 7s iPhone I tried the home button does no haptic feedback and does not work well.

  As it was a display model, of course, I'm curious - are these kinds of common problems?

  I just posted my concern in this regard. I have the 7 +.

  and the home of the Taptic button does not work. I have to still physically, press on the

  button as I did with the 6 +. So what is the difference?

• Haptic on Apple Watch not working

  Hi all.  So I have a problem with my Apple Watch which becomes quite frustrating.  The haptic feedback doesn't always work.  When I get text messages, it does not vibrate all the time.  The sound works 100% on the watch, but isn't the haptic feedback.  When I say, "does not vibrate all the time", I mean that I have to constantly manipulate the haptic feedback adjustment in the settings or forcefully bump/tap the day before for the haptic feedback work (as the engine does vibrates is stuck).  I'm pretty smart Apple then Yes, I adjusted the settings, unpaired, cleared, reset and also had it sent to Apple for repair.  Unfortunately, Apple technicians have not replicate my problem which is most frustrating.  On the Apple Store, the representative has not even tried to solve my problem and just told me that he would send my watch to get looked at.  Does anyone else have this problem?  I've just updated IOS to 9.3.4 on my iPhone 6 s more and that did not help either.

  Hello

  I suggest that you stick with Apple Support.

  Given the steps that you have already tried, the symptoms are indicative of a problem with your watch.

• Problem with vibrations of the Iphone 5 and SE

  Hello, my name is Alexander, im of the Brazil and I speak very well English. I owned an Iphone 5 purchased in Italy in September 2012 and I used it until today 02/08/16 when I decided to buy a SE 64 GB my iphone because Iphone 5 was a problem that could not be resolved. I used it and noticed the battery was swelling and suddenly the Iphone 5 continues to vibrate in all operations. I took it to the interview and they changed the vibrating motor and the power cable, cable, but does not work. I thought it might be a problem with the motherboard by the blown battery occurried. So I decided to buy a SE 64 GB and when I restored the Iphone 5 in SE, it runs with the same problem. The store give me another a 64 and after the restored backup, the same problem occuried. They had upgraded the operating system, but the only way to solve it was a complete reset of fabric and make a backup of restore contacts and photos through the Icloud

  Can someone help me?

  There are a few app couldn't stop the iphone vibrates? without all my applications and files, the SE Iphone works fine

  I don't know if you want vibration on or off. Anyway, this is the setting you are looking for...

• Updated Firefox to version 23 - several problems

  Hello.

  It is my first post in this forum, even if I'm a long-time Firefox user. I'll take the chance and thanks for all the effort you put into providing the best browser to Mozilla and keep the web open.

  Everything worked great until I allowed Firefox update to version 23 today.

  I have multiple problems, maybe more that in any process to upgrade to this day, that's why I take my time to write this post and hopefully provide a feedback to do better in the future Firefox releases.

  1. in the previous version, I got all the plugins that have been blocked with the parameter 'plugins.click_to_play' set to true. At the present time, I am aware that it is possible to set this option individually for each plugin in firefox > extras > plugins, the problem is now I have to turn them all to "always ask", even if click_to_play is always true and in "subject: permissions", I always always "ask" activated. This makes no sense and it goes against the functionality of Firefox introduced not so long ago, click to play the plugins in each page.

  2 - Youtube videos stopped working, they charge not at all and sometimes youtube report "an error has occurred." I tried with active plugins and click here to read, but nothing works. However, DailyMotion and Vimeo videos are loading very well so far.

  3 - Facebook Messenger for Firefox stopped working too. I deleted and added to many times, login and logout of facebook, by following the steps to troubleshoot this https://support.mozilla.org/pt-PT/kb/how-does-facebook-messenger-firefox-work but nothing seems to do the job, the cat remains empty of zero it and buttons for the updates and friend requests do not appear yet.

  I'm also a bit annoyed with the change in research, I usually kept two different search engines, an impressive bar and the other in the search bar, it has been very helpful. Now, when we change the motor in a bar, it's the same in the other, then why keep the search bar at all? Why not integrate in the awesome bar? This change is not sensible as well. Let's say I googled awesome bar and want to search DDG, I must change first and only then search, but then I have to come back once again, this is a very regrettable decision. If it is to make it easy to change the default search engine, this should be found in the settings.

  Furthermore, I don't think that quite remove features of the browser is the best way to keep the part of the user for that matter, with various search engines could remain an option for those who want to, can say the same about the disabling of tabs, even if some of them should never be used by most people It does not mean that they do not serve. Configurability is always special Firefox, the possibility to make it * your * browser.

  Even if I'm frustrated by these problems, please take this as constructive feedback. I always will support Firefox all the ways that I can!

  BTW, I love the new logo design!

  I was able to understand the problem with Youtube videos

  "An error has occurred. Please, try again later"appears on every Youtube video since I've upgraded to Firefox 23 in two of my personal profiles, although many others such as DailyMotion or Vimeo worked well.

  After you start in safe mode, starting to play Youtube videos and I found the problem was caused by HTTPS Everywhere extension (by EFF) https://www.eff.org/https-everywhere

  So in Firefox 23, apparently Youtube can't play videos in a secure HTTPS connection.

  For those who have the same problem, because it doesn't happen on Youtube and nothing else (as far as I know), there is no way to disable this add-on, simply go to its options in Firefox > Add-ons, search for Youtube, right click on the entry and select alternative to disable the connection on Youtube.

  Regarding Facebook Messenger, its seems broken for many people, as you can see in the following positions

  https://support.Mozilla.org/PT-PT/questions/967502
  https://support.Mozilla.org/PT-PT/questions/959474

  It is not something on my Firefox configuration, because it is broken on a newly created profile as well and others suffer from the same thing, if I can just sit and wait for a fix to be corrected, meanwhile I'm disable.

  Click to play plugins is a work in progress on Firefox, so I hope it is addressed in the next version. Set to true in: config should require activation for them all, but it's not the case, since they are all still active in Firefox > Addons > Plugins. The solution is to require the activation individually for each plugin.

• Vibrate and haptic does not not on my new iPhone 6 s

  This has happened twice already, my iPhone 6 s that I just noticed that the vibrator or the haptic function no longer works on my iPhone 6 s. And I tried to put the phone on silent and using the 3D Touch feature, but not luck. The 3D Touch allows me to go down the features, but no haptic feedback. After that I restarted it works normal again. Clues? Is it a hardware problem or a software problem

  If the haptic returns to normal after a reboot of the device, you can be sure the question is almost 100% software.

  The concern being that the erasure of the device and setting up as new may definitively prove the only way to solve the problem.
