64 bit motion control ready now?

I recently upgraded LabVIEW to 2010 64bit. Then it turned out the previous motion control VIs don't function in 2010 64bit version. The error points to the failure to load "FlexMotion32.dll". It makes sense, apparently that DLL file is 32-bit.
I did a search on ni.com about FlexMotion. This page http://zone.ni.com/devzone/cda/tut/p/id/3753 illustrates that "FlexMotion32.dll" is required for the communication between LabVIEW and motion controller board. Tried to find if "FlexMotion64.dll" is available, but it doesn't seem it exist yet.
So my question is how I can update the motion control to 64 bit.
Solved!

Hi Ian
We value your feedback on our NI-Motion Software. We have a limited amount of resources but will take your recommendations into account for the driver. I am sorry that we do not have a 64 bit driver for NI Motion and hope that this does not slow down the development of your latest project. Please let us know anytime you have feedback we are always trying to take into account what our customers need and manage our time according to it.
Thank You

PWM in Motion Control

HI All,
I am facing a problem in Motion Controller.
We are using PCI 7344 and UMI 7774.
Now their is a connector on the Motion control card for Digital I/O.
In this Pin No 5 and Pin No9 are PWM1 and PWM2 respectively.Now I have used to VI PWm duty and config PWM. I am seeing the PWM waveform on CRO.But to my surprise the output is not matching the required data.
IF you go for HElp and click config PWM VI block , you can see a table given where the internal clock selected corresponds to a particular frequency in 734X and 735X.Now since I am using 7344 my frequency should match with 734X table , whereas this is not happening and
my frequency matches the table of 735X.
SO i am bit confused about the controller specs or is someor the other way Iam missing some thing more.
Regards

Manish,
please have a look at this table which comes with the NI Motion function help file for NI-Motion 7.2. This table should contain the correct values. The latest revisions of the 734x are named 7340 and the PWM output should follow this table.
Best regards,

Photos in Timeline and Ken Burns Effect (Motion Control)

I'd like to check my processes for setting photos with the Ken Burns Effect. I've used Tom's Motion Control example to set Ken Burns Effect on two or more photos that are next to each other in the timeline. I have found that if the photos are approximately the same pixel size that it works well. When they are significantly different I still see the second pic holding still for a few frames and then the movement.
So, I'm interested in other experiences. Did you also find that the relative size of the photos makes a difference? And, when you have photos that are significantly diff in size, what process do you use to bring them closer together?
Thanks,
dave

Hi David,
I think the problem you are having is similar to one that I was encountering while finishing a project a few weeks ago. I also was using photos of differing sizes, but the issue with the late start on the "Ken Burns Effect" on the second photo wasn't related to the differing photo sizes, but to the transition I used between the images.
I found that when I applied Motion to a photo using keyframes, the motion looked fine on both images until I applied a cross dissolve in between images. I realized that the cross dissolve is looking for frames before the motion keyframe to blend with the previous photo. Since the frames before the keyframe are "generated" (I'm not sure if that's the correct word) from the first frame of the still (which has no motion) it generates 15 frames (for a 1 second cross dissolve) that are not moving. That makes it appear like it's stuck and then starts moving when the playhead hits the motion keyframe.
My solution was to move the still photo clips (one at a time) up one video track, extend both ends 15 frames and set the motion keyframe at the "new" beginning of the clip and the "new" end and do my motion based on that new clip length. I then brought in both ends back to their original positions and dropped the clip back into its original spot and then applied the cross dissolve. Now the cross dissolve would have 15 frames with motion to work with for blending the two pictures.
It was incredibly tedious, but I had to do it because the images made up a large part of the video project I was working on. If anyone can suggest a better way of doing it, I would greatly appreciate it.
Despite the time involved, I was really happy with the final results.
I hope that helps.

If you are a long time Nokia/Symbian fan then you will Know full well that Nokia phones ALWAYS improve with software updates, Symbian will not be abandoned and will not be replaced by WP7, it will continue to evolve and improve, as will the handsets. Anyone who desires or wants a different OS should try one, because it's a free world, but really, the 'perfect' OS doesn't exist, and Symbian suits me for now and I will rely on Nokia to keep it up to date, and reliable.

Motion Control via Serial Port

I have previously developed an automated video microscope application in Labview. It worked great. My setup was: NI PXI system with 1409 image board, 7344 motion controller, 7764 breakout box, stepper motors, motor drivers, and tables. Now, a customer is requiring that we use a specific brand of drivers that encompass a motion controller and are daisy-chained together. Communication will take place from a serial port, thereby bypassing the 7344. My question is: will I have to can my entire previous Labview motion/data acquisition program b/c I won't be using the 7344 controller? Or, will it be easy to specify in the program to commmunicate via the serial port rather than the card? Would this setup take place in MAX, or in the LabView applicatio
n itself? Any nuances that I should know about? Any info would be appreciated. THANX-ROB

Rob,
in this case you won't be able to use any of your motion related code. The motion VIs in LabVIEW call the NI-Motion driver dll and thus they are not hardware independant. By the way, this is not a specific disadvantage of the NI-Motion driver. In fact there is not such a thing available like a standardized interface and hardware independant motion control language.
In general you will have to use low level serial communication (VISA). That means you have to read the drive/controller manual, identify the serial command strings you need and send them to the device.
For configuration the drive vendor should provide a utility to set the necessary parameters.
On the other hand you could be lucky in the case that the vendor of the drive/controller provides h
igh level LabVIEW vis. You should check with this vendor if a LabVIEW driver is available. Still you will have to rewrite your motion related part of the code.
I'm sorry that there are no better news.
Best regards,

Can't turn off motion control

Hello everyone,
First time on here. Just got a u410. Anyway I downloaded adobe reader. When I opened it I got a message that said motion control can be enabled for this application. So curiously, I turned it on. But now I don't know how to turn it off. Everyone time I open adobe reader, the camera automatically turns off. How can I turn off motion control?

Seriously?! There has to be a simple way to switch off the quite annoying Lenovo Motion Control...?
I have now been using it for a while, but in general iit is more of a nuissance - any movement in front of the screen when presenting makes the slideshow jump ahead or back.
If I click the little message in the top right corner announciing that motion control is activated (it says something like "click here to configure") absolutely nothing happens. If I click the Motion Control icon (on the Start page) the computer switches back to the last program used, no matter what it was, and then nothing else happens...
What is the right way to really switch this function on/off...???
Sorry, but my suggestion does not apply to your situation. I responded to the original post. I have not read your problem when I made the suggestion. You should know that. Maybe you should try openning a different thread, not bump the orginal one.

PXI ethernet activation requires initializing motion control?

On a PXI with multiple 7344 motion control cards and an ethernet LAN connection, ethernet does not become active (e.g., flickering LED on the PXI controller connector) until the 7344 card is initialized. Shouldn't ethernet become active as part of booting up?

The behavior is no longer reproducible, although several combinations of booting and plugging in the Ethernet cable were explored. LAN access is now available promptly upon booting or connecting the cable, as expected. A residual explanation might be that Win2K on the PXI 8175 controller did not fully respond when DHCP on the local router/firewall changed the PXI's IP address, due to changes in the network configuration. In this case, initializing the 7344 cards is taken as an event that caused the OS to complete LAN activation. Many other events with other hardware might have had the same effect.

Ni pxi motion control, data extraction

hey,
i am using NI PXI Motion control system wid kollmorgen AKD servo drive. The drive has been successfully operated. But now is there any way i can extract real time values of current, speed and torque of the servo motor being controlled. And can this extracted data logged into an excel sheet??

Keyframes and motion control

I would appreciate sources of information that would explain Motion Effect/Keyframes to a nonprofessional. I have read three books and can't get an understanding. For an example: If i change the motion controls position from 360 725 to 360 240, what am I doing? I would appreciate any help or reference material. Arnie

First, here is a TUTORIAL on basic Keyframing. It was written for an earlier version of Premiere, not Elements, but covers the basic theory.
Now, in your example, think of the Video Frame as a picture frame. It is fixed on the wall, and you have a picture inside of it, but can see nothing outside of that frame, only what is inside of it. What you are doing with Effect>Motion>Position is moving the picture behind that Frame. Same with Motion>Scale. Now, with keyframing, you can alter the position of your picture behind the frame over time.
Hope that this helps.

Is it possible to generate a motion control vi from parameters entered into MAX?

In the process of familiarizing myself with LV, It was brought to my attention that it might be possible to generate a VI from parameters entered into MAX. Is this possible?
Right now, I am getting familiar with motion control and LV by using MAX's 1D and 2D motion controller interactive environment. I was wondering if there was a way for LV to take the parameters and selections I have made in the various fields and make a VI from it?
I have tried searching MAX's help, Google searching, etc. but have not found anything.......
Thanks

In LabVIEW you can use "Initialize Controller.flx" to load the configuration settings from MAX to the motion control board. There is no way to create vis from the Interactive window, but if you are looking for such a feature, you may want to look into the NI Motion Assistant.
NI Motion Assistant is an interactive environment for prototyping your motion control application without programming. Later you can export your motion sequence to LabVIEW.
If you want to test Motion Assistant, you can download an evaluation version here.

Identify motion control board

I'd like to identify a motion control board and get the according manual. There's no product number on the board, except the following numbers and names:
PCIstep
Assy: 184903C-03
184905B-01
The device is named
PCI-Step-40X MotionValue
in the measurement&automation explorer.
Could someone identify this board?
Thanks in advance,
simon

Simon,
What exactly do you want to know about this board?
I know very little about this board.
What I can tell you is that it is a very old board which has been obsoleted and is no longer supported.
As a value motion board you may have some luck scavanging through the ftp site at ftp://ftp.ni.com/support/motion/Software/PC/ValueMotion/
You can find information on our current line of Motion product here.
Hope this helps at least a bit.

How can I use flex motion control VI without hardware?

I would like to try and simulate the motion control of my system before i hook up the motion control card. But when I use the VI in flex motion contro took kit it asks for address or something and gives me an error. Can't I just simulate without hardware?

Hello,
The only way you can use FlexMotion without any hardware is to set it up as Open Loop Stepper Control. Otherwise, you will get errors when no encoder signal is fed back to the controller.
Please let me know if you have any further questions.

Yoga 2 Pro - Motion Control

If this has been answered, or solution(s) offered, I'll be darned if I can find them, even an extensive search in the Forum and Community Database...
New Yoga 2 Pro for Christmas...so far, very nice machine. However, am a litlle (!) frustrated with the Lenovo Motion Control...
I can get the software to open, access settings, etc. but the tutorial doesn't tell me squat. Activating the software doesn't open my webcam...I tried with a couple of other programs, and when opening, they DO boot the webcam on. I can't find any step-by step instructions on the 'net...heck, the Dragon Assistant software tutorial is great and got that running fine.
It appears that this is a common issue, judging by the number of posts on Lenovo Community. I tried uninstalling the original software, then reloading. I tried downloading v2.0 (it came preloaded with v2.5.1.0225 to ses if that would work, as suggested in a posted fix.
So...no Lenovo support for Motion Control? No workarounds or fixes? Is this a glitch with Win 8.1 that has yet to be resolved? Inquiring minds would sure appreciate knowing! Thanks for any assistance in advance!

I dont have my Y3P at the moment but I remember disabling it from Task Manager > Startup Programs
Find Motion Control in there and Disable it, then restart the system.
You should probably also disable Harmony, since that is the app which is responsible for these transitions and gets annoying for me.

Where is the output for PWM on NI 7774 connected to motion control card 7356

Hi,
I have NI motion control card 7356 which interfaced through 7774 interface board. PWM outputs are written to be on pins 5 and 9 on Digital IO, yet there is no indication about the whereabouts of these PWMs on the interface board (7774). Would you please help???
Asst. Prof. Vasfi Emre Omurlu, Ph.D.

Simitci,
For the digital I/Os a UMI-7774 provides access to 16 digital lines. If you want to access other signals of the digital connector, you shouldn't connect it to the UMI but to another breakout box like the SCB-68. Please note that compared to the UMI-7774 the SCB-68 doesn't provide optical isolation or 24 V connectivity. If this doesn't work for you, you could think of building a customized cable that connects the lines for the16 digital I/Os to the UMI and the rest of the signals to another connector or breakout box.
You also should be aware of the fact that the PWM outputs of 73xx boards are static. That means that you can change the duty cycle and output frequency of these signals in software only, which is quite slow. In most cases these PWM signals can't be used for motion control tasks.
What do you intend to do with the PWM signals?
Thanks and kind regards,

Homing switch causing motion control problems

I am controlling a dome for a telescope. I have a home position switch and motion control using one of NI's motion controllers. Everything works fine except for one bug. The dome just goes around and around. I can run a Home type reference search and it works fine. But if I command a position that runs through the home switch zone the dome stops moving. If I hit the command a second time it runs right to the correct position.
So why does the home switch stop the motion if I am not doing a reference search. Should I be using some other form of referencing?
Thanks,
Dave
David A. Taylor

Do you have the home switch also configured as a limit switch?
What motion hardware are you using. In addition to home limits, the ni cards often have a + limit and - limit and also a software limit, these can be configured via the api or in max.
