écrire et lire sur pci 7344

Bonjour,
Je desire transmettre une string pour piloter un moteur gammatic un axe.La carte PCI 7344 doit me permettre de transmettrea l'harmonic drive(variateur
sc510) mais j'aimerai egalement lire se que me renvoie le variateur.J'ai auparavant essaye motion assistant mais sans succes. Pourriez vous m'indiquer quel methode je dois suivre pour savoir si ce logiciel reconnait le moteur.D'autre part je n'arrive plus à désinstaller ce logiciel sur un autre ordinateur malgre que son repertoire soit effacé(le fichier a été supprimé) mais il doit rester des cles dans la base du registre et je ne peux plus le reinstaller. Que puis je faire pour le forcer a reinstaller? Pourriez vous également m'envoyer les VIs qui permettent d'écrire et lire sur cette

Je pourrais trouver le manuel pour le Sc 610. Si la commande de Sc 510 est semblable, alors elle devrait avoir des entrées pour des signaux de Pulse/Step et de direction. Les 7344 peuvent être configurés pour le mode de moteur de pas en utilisant l'explorateur de mesure et d'automation qui obtient installé avec le conducteur de Ni-Mouvement. Vous pouvez alors employer une interface UMI-7764 pour relier les 7344 au Sc 510 et pour les conduire de cette façon.

Ecrire et lire sur deux voies physiques synchronisés par trigger analogique

Bonjour,
Je possède un carte NI PCIe6259 et deux connecteurs BNC 2110 et BNC2111 pour faire mes conections.
Je souhaiterai lors d'un top synchro analogique déclencher l'écriture sur une voie et la lecture sur une autre voie.
Les exemples fournis permettent (VI trigger numérique) de faire cela en utilisant un trigger numérique que je crée grace à un compteur et que je lis sur la voie PFI13 de ma carte d'acquisition.
J'ai trouvé deux autres exemples qui permettent de séparement écrire ou lire sur un voie en déclenchant sur une voie externe analogique. Il suffit de connecter le trigger sur la voie APFI0 de ma carte. Cela fonctionne
J'ai donc essayé naïvement de rassembler les deux VI dans un même VI (cf fichier) mais ca ne fonctionne pas. L'erreur indique que la ressource spécifiée est réservée. Peut être s'agit-il de la voie APFI0 qui est utilisé deux fois. je ne sais pas trop.
Avez vous déjà rencontré ce problème. Doit on utiliser deux voies APFI différentes ? (mais je n'en n'ai qu'une de disponible sur mon connecteurs BNC2110)
Merci d'avance

Bonjour,
Je vois une erreur, qui est au niveau du Start de tes fonctions. Le mieux est d'utiliser le cluster d'erreur pour créer un séquencement dans tes opérations. Du coup, il faudrait faire le Start de l'AO, puis le Start de l'AI, et seulement après faire le Read.
Autrement ca m'a l'air correct.
Dans ma précédente réponse, je te disais que la première solution était meilleure, car les 2 acquisitions sont déclenchées en même temps, et peuvent utiliser des horloges différentes, dans la solution que tu as choisie, tu as compris que les 2 tâches partagent la même horloge. Un avantage est que l'acquisition et la génération se font exactement sur le même front d'horloge. Mais dans la première solution, si tu mets la même valeur de "Rate", le driver gère tout seul le fait d'utiliser la même horloge.
Je ne comprends pas très bien ta dernière question. Il n'est de toute facon pas possible d'acquérir ou générer un front sur deux, à moins de passer par un compteur qui va regénérer ton horloge, mais là où je ne comprends pas, c'est que pour que tu aies ce comportement, il te faut une horloge ecterne, or, dans l'exemple que tu montres, tu utilises l'horloge interne de la carte, et c'est du coup le "Rate" de l'AI qui cadence l'acquisition, donc il est réglable. Si tu veux utiliser une horloge externe, il faut que tu déclare la source d'horloge pour ton AI.

Comment mettre en place mon système(table xy,LabVIEW 7.1,PCI-7344 et le TL78 )?

Je suis un nouvel utilisateur de le système Motion Control(table xy, TL78, PCI-7344, Windows2000 et LabVIEW 7.1 ).
Je voudrais contrôler les table xy(MC)à partir de Labview.
J'ai télécharger Motion Assistant et des programmes de test et de contrôle.
Lorsque j'essai "program demo".
Modal Error indique une erreur 70137
si je lance "Test single axis" alors il m'indique l'erreur 70129 pourtant
ma configuration de l'axe est "enable".
Je n'arrive pas à paramètrer le système, malgré mes recherches sur le site de NI.
Je ne comprends pas comment exporter les signaux sous Labview.
je suis perdu!!!
Que dois-je faire??

First of all, before connecting the drive to the 73xx controller I would check that the drive and motor configuration works correctly independent from the controller. The Gemini drives have a utility called the Motion Planner that allows you to configure your motor and drive for independent operation so you can test if the motor and drive combination are working by themselves. Refer to page 18 of the Gemini GV installation guide which you can find at the compumotor site or download from:
http://www.compumotor.com/manuals/gemini/Gemini_GV_HW_Install_Guide.pdf
Once you have tested your motor and drive combination, make sure that the drive is configured in torque mode and that the command signal is configured to be sent from the I/O connector and not through RS232 using the Motion Planner. The next step would be to connect the 7344 through the UMI-7764 breakout box in the following order:
---- UMI7764 GVU6E
---- AOut Cmd+ (pin23)
---- AOGnd Cmd- (pin24)
---- InhOut Enable- (pin2)
---- +5V Enable+ (pin24)
7344 --> EncA AX+ (pin8)
---- EncA- AX- (pin9)
---- EncB BX+ (pin10)
---- EncB- BX- (pin11)
---- Index ZX+ (pin12)
---- Index- ZX- (pin13)
---- +5V Encoder +5V (pin5)
Verify that your enable line is connected in an open collector mode (as shown in the diagram above). Our inhibit outputs can sink current but not source it so if your enable line is not behaving properly you want to make sure that the +5v supply you are suing for the UMI can source enough current for your enable line to work. Consult Compumotor on the specs of their enable switch.
Once the connections are done properly, all you need to do is configure and initialize your board for servo operation in MAX and then you can start your tuning process. Refer to the Tuning PID for servos tutorial in:
http://www.ni.com/support/motnsupp.htm
for instructions on tuning your servomotor properly. Also for more information on using MAX, refer to the following tutorial:

Using Mitsubishi A500 inverter with PCI-7344

Another question..
I am planning to use PCI-7344 to implement speed control for 7,5 kW
induction motor. Mitsubishi A500 inverter driving the motor seems to
have only speed (frequency) setting input. This axis don't have to make
rapid movements, instead I'm looking for accurate speed and mostly
rotation in one direction only. In the same machine there are
servoaxises with Mitsubishi J2S servocontroller and they work OK.
Movements of servos should be syncronized to the rotation speed of main
axis.. I am asking this because it says in the manual that torque
control should be used.
There are two pulse encoders in that 7,5kW axis. One in the motor and
another in spindle axis after reduction gear. There is also orientation
control/PLG feedback/pulse train unit (FR-A5AP) installed to the
inverter. I'm not sure if that should be used or not.
Tommi

Tommi,
it's a bit easier to tune a system that works in torque mode as typically you only have to tune the position PID loop of the board. That's why torque mode is recommended but that doesn't mean that you can't get good results with velocity drives, too. With a drive that works in velocity mode you will also have to tune the velocity PID loop of the drive and you will probably have to use Vff and Aff parameters of the PCI-7344 to reduce or eliminate the following error.
In order to get very accurate velocity and position control you should use both encoders of your 7.5 kW axis. The encoder that is attached directly to the motor should be configured as secondary feedback device, the other one as the primary feedback device. Please follow this link for further instructions. Also have a look at this tutorial, especially at the "Dual position feedback" paragraph.

PCI-7344 limit and home inputs type

Hello,
I am trying to find out what type of switches will work with PCI-7344 (4-Axis Stepper/Servo Controller for PCI) limit and home inputs.
If i have NPN or PNP switch as the input to the limits and home input, will it work?
Thank you,

JB,
I saw that on the user manual. But, it wasn't clear.
Basically, I am trying to find out if I use a PNP or NPN type switch at the input. Will that work? Also, on the software, we have set all home and limit inputs to active high.
We are designing a new electric actuator to work with PCI-7344. The electric actuators will contain either NPN or PNP magnetic switches. Before, we finalize the design, we have to make sure that these switches will work with PCI-7344
Thank you,

Open Loop Problem of PCI-7344

Dear Partners
I have a big trouble....
Any suggestion would be appreciate!
Here is the hardware and software that I am using
S/W : MAX 3.1.1
           LabVIEW 7.1
           NI Motion 7.0
H/W : PCI-7344
           UMI-7764
           YASKAWA Servo Driver
I've tested my motion B/D step by step
1) Start Max3.1.1 / MySystem / Devices and Interfaces /NI Motion Devices /
       PCI7344(1)/Interactive/1-D Interactive
2) Slect "OPEN LOOP"
3) Input steps : Velocity, Acceleration, Deceleration
4) Input steps : Target Position = 100000
5) Click "Apply"
6) Click "Start"
But sometimes it stops generating steps.
it occurs very very irregularly.
I can't understand because I use "OPEN LOOP"
and "Current Trajectory Position" must increase until "TargetPosion" whether the asis move or not.
Also there is no limit signals..
Please see the image file attached.
It's very simple I control motion b/d with OPEN LOOP MODE.
and, I think the servo Driver works well because command steps and encoder pulses are equal.
Please Help me!!!

Thank you Jasper S.
I think you understand me well.
I tell you more informations.
1) The computer is working in Windows XP Professional (Just Theme).
2) It happens also at low velocity and acceleration.
3) I think when the motor stops moving, it fails to translate into hardware steps.
Because when the motor stops, "Current Trajectory Position" and "Encoder Counts" are equal.
4) I checked status registers on the card when it works abnormally, but can't find any error message and flgs.
5) To make matters worse it happens occasionally, so it's difficult to find out the reason.
6) Strange as it may sound, when I touch the motion connector correctly,  the abnormal behavior frequency decrease.
So I tried to exchange a new motion b/d and a motion cable but it was just same error situation.
I can't understand because I just use "OPEN LOOP",  it is no matter whether servo driver works well or not.
7) Do I have to change PC? I already tried to exchange PCI Slot position.
I need more information about this.
I'm in trouble because this system is operating at foreign country.
It is fatal error even if it happens once per day....
Please help me once more. Thank you.

Position Control of compumotor linear servo table and GV-U6E with PCI-7344

I'm referring PCI-7344 (not 7334).
I have the GV-U6E which is a drive only and does not possess control functionality. the drive only version does not store or use programs. So, serial commands can not be sent through COM port by LabVIEW even though A few basic commands can be emulated.
I am trying to do position control as I mentioned. For example, the motor should move A point to B point exactly with a certain speed. The points must be aboulte position.
I would like you to see the reference comment that I have been contacting with in your website forum.

Yes, we used an NI PXI-7344 motion control card with an NI UMI-7764 box connected to a Gemini GV-U12E servo drive. (which is a drive only.)
We did positional control in absolute position mode.
I can send you an AutoCAD schematic detailing how to connect the UMI-7764 to the Gemini GV servo drive.
In regard to the Rs232 interface to the GV servo drive,
the GV drive only model is "configurable" not "programmable". You can create unique GV configuration files with Compumotor's Motion planner then download the configuration via Rs232 using LabVIEW as desired. Or, using LabVIEW via Rs232 you can change individual GV drive parameters on demand,
or use the GV's two analog outputs back to LabVIEW's analog inputs to measure commanded motor current or torque, etc.etc.etc

PCI-7344 not found in MAX 3.1.1 after installing NI-Motion 7.0

Hi,
I updated my PCI-7344 + LabView 7.0 system with the newest NI-Motion 7.0. After the update the card was not anymore detected in MAX. There was a "broken" device PCI-7344 under NI Motion Devices, which status said something like "This device has been removed or could not be detected" and the Reset command said something like "Could not communicate with the device. Power cycle the computer..". I removed the device from the "Devices and interfaces" list and since that, MAX hasn't had a clue about the card. I've tried the "Create new.." function, but it doesn't show any NI Motion Devices or PCI-7344 anywhere else. I've also tried the Tools/Install legacy driver support, but MAX only notifies that the updates are OK. I've also tried removing the physical device, starting the computer and MAX, reinstalling the device and restarting MAX, but nothing changes. The device is recognised by BIOS as "Unknown device"; in Windows 2000 Pro, the device is well recognised as National Instruments PCI-7344.
One thing that could cause the problem is that I also have LabView 6i installed on the system, although I'm not currently using it for any purpose. Anyway, this seems to prevent the MAX from detecting the correct updates needed when using the "National Instruments Product Updates.." from Tools menu. Perhaps I need some driver software to correct this problem?
I also tried to uninstall the NI-Motion 7.0 and to install the NI-Motion 6.1.5, but after this, the MAX did not work correctly. For example, none of the branches in the configuration tree would expand and the MAX locked up when trying to use the Create New.. / NI Motion Device. Is there a way to uninstall the NI-Motion 7.0 and to replace it with NI-Motion 6.1.5 without removing all NI software from the system?
Before the update, with NI-Motion 6.1.5, the PCI-7344 card was correctly found in MAX and well usable in LabView 7.0.

Jouni,
A valid serial number is any number > 0. If you have multiple boards in you system, they must each have a unique serial number. This would be the case for any board coming out of manufacturing. The board Jochen had probably came from R&D and was a prototype board.
Your problem with downgrading from NI-Motion 7.0 to NI-Motion 6.1.5 was most likely due to the data stored in the MAX database. When you uninstall NI-Motion, the data in the MAX database remains. The NI-Motion 6.1.5 driver would not have been able to read the data correctly. The easiest way to "clear" this database is to delete the c:\Program Files\National Instruments\MAX\data folder. The only other way is to uninstall MAX, which requires that you uninstall everything. WARNING, Deleting the MAX data folder will delete all MAX settings and set them back to defaults for all NI hardware (uninstalling everything has this same affect, by the way). Downgrading is never as clean as upgrading.
The firmware on a Motion board can always be downgraded by forcing the download of firmware files. To do this, select the board in MAX under Devices and Interfaces. Click on the Firmware tab at the bottom on the window. Highlight "PCI-73XX Firmware" by clicking on it once. Right click on one of the items in the "Firmware name" column to the right. Select "Download All Files".
I do not have a good explaination for why NI-Motion 7.0 did not recognize your board. Do you have a second board you can try in the system? If not, could you ask your local sales representative if they have one you borrow for a quick test? Since the board is recognized by Windows 2000 Device Manager, I don't think there is an issue with the board, but it doesn't hurt verify this.
My best guess is that there was a confict during the installation process and your system did not get all of the required files. Though we do significant installer testing, there are rare occasions when a system is in such a state that the installation process does not function as expected. It is my experience that these rare instances do not occur on clean machines, but on machines that have had multiple products installed and uninstalled. If you do get a chance to try NI-Motion 7.0 again you may want to use these parameters to get the installer to create a log of the installation: "c:\setup.exe l*v c:\log.txt". This assumes that the setup.exe is in the c:\ directory. Go to start>>run and type this in without the quotes. The log file will be named log.txt in the c:\ directory.
Finally, you can technically use NI-Motion 7.0 in LabVIEW 6. You just need to copy the C:\Program Files\National Instruments\LabVIEW 7.0\vi.lib\Motion folder to the vi.lib folder of LabVIEW 6. Though this is not officially supported, there is no reason it shouldn't work.

Connecting Yaskawa Sigma II Servo Drive (SGDH) to PCI-7344 and UMI-7774

Hi,
I have NI PCI-7344 and UMI-7774 and i want to
Connect the UMI-7774 to Yaskawa Sigma II Servo Drive (SGDH) , the servo motor drive is connected to the servo motor with original Yaskawa cables.
1.  do you know if National instruments provide special cables to connect the UMI-7774 to the Yaskawa Sigma II Servo Drive (SGDH) ?
     i know there is special cable to connect this servo drive to the NI PCI-7390
     http://zone.ni.com/devzone/cda/tut/p/id/5908
(you can find in this link that this cable exist: 50 Pin cable for connecting MCA-7790Y to Yaskawa Sigma II Servo Amplifier)
     but this is not the case here, i need to connect the Servo Drive to the UMI-7774..
2. Where can i find a tutorial on how to configure the PCI-7344 in MAX to send simple commands to the Servo Drive
      i.e. to run the servo motor from position A to position B (10,000 encoder pulses)
i'll be gratefull for any help
Regards
Moti

Hi MotiM,
We do not have a cable that will let you directly connect the UMI-7774 to a Yaskawa Drive. We do sell cables that will have the Dsub connector to match the UMI-7774 with pigtails to wire to the drive. If you take a look at the product page for the UMI-7774 you can see the different cables listed under the accessories.
To perform a simple move in Measurement and Automation (MAX) is very simple. In MAX under NI-Motion select your PCI-7344. Under this section select the settings option (by default it will be called Default 7340 settings). Select the Servo radio button. Initialize your controller. Then you can select Interactive and 1-D Interactive and command your motor from there. I have attached an image with the important areas highlighted for you.

Seems like my PCI-7344 has one axis faulty. Please help

Hi all,
I have a PCI-7344 with UMI7774. I am trying to read the position of a encoder connected to Axis1. But when I move the encoder shaft, the counts dont change in LabVIEW or MAX. When I connect the same encoder to Axis 2,3 or 4 then the change in encoder counts occurs. When I press the "Test resources" button in MAX it says that "The device passed the resource test successfully !". What can be the reason? Does it mean that the UMI 7774 is faulty? What does "test resources" mean??

Giridhar,
"Test resources" only tests if the PCI-7344 is installed correctly in the PC by checking the communication resources that are assigned to the board. This is not a functional test of the board.
The problem that you see could be caused by a defective UMI-7774, PCI-7344 or the motion cable. If possible please exchange these components one by one with other components that you know that are working properly. I think the most probable reason for this behavior would be a defective UMI-7774 but there is also a small chance that one of the other components is broken.

PCI-7344 motion controller encoder reset problem

I'm using a PCI-7344 motion controller for my application. I'm currently working on simple display of position and velocity using an encoder. I am able to read the encoder pulser, but I am unable to reset it. I want the encoder pulses to be display continously till I press a reset button on the screen. After pressing the reset button on the front panel, the encoder count should become zero and start counting again till I press stop button. Kindly give me a simple example of encoder reset using push button. Thanks.

This should do what you are looking for. I am not at the computer that has a motion controller card in it, so I have not tested it.
It resets the encoders for Axis 1 and Axis 2. Unless you have a different configuration for encoders and axes, it should work.
Hope that this helps,

Windows 2000 upgrade from win98--will i have problems with my pci-7344, pci 6110e & ni5411?

I am running win98 with my Labview 5.1. It running fine, but I would like to upgrade the os to windows 2000.
When I was running a check of the hardware, win2k said that the following hardware may not run:
pci-7344, pci-6110 & ni-5411.
will i need new drivers?
will i run into any problems?
any suggestions?
thanks!

Byron,
You should not have any problems when you upgrade your OS. Depending on what driver versions you have for that hardware, you may want to go ahead an upgrade your drivers anyway, though. The drivers for these devices are all available for free from our website at:
Current Driver Versions
http://digital.ni.com/softlib.nsf/webcategories/9AD71162B755F0E786256BBC005F001A?OpenDocument&node=132060_US
Try that and let me know if you have any trouble.

PCI-7344 Device status error

MAX returns some errors after PCI-7344 installation with the last NI Motion Driver,
1- Max returns a message: "reset board before update firmware" when I try to update the firmware
2- returns another message: "Restart PC to power supply again the board"
3- When restart PC I obtain two message:
A- NI-PAL Service Manager encountered a problem and needed to close
B- NIMax has encountered a problem and needs to close. We are sorry for the inconvenience
4- Reinstall entire operative System and Driver, Labview and MAX is necessary to obtain a stable function of MAX because these error messages come back after I unistall the PCI-7344 board from PC also. (I use Norton Ghost to restore entire system for my luck)
Thanks for suggestions
Francesco

Assuming NI, the card is a PCI-GPIB.
The error ( Unknown system error (miscellaneous error).), doesn't say much. I would recomend doing the test of the card in MAX and see what happens there. Since MAX does not use VISA for instrument communication, you might have a problem with that though if NI-VISA was not installed at all, you would have a different error code. Is the instrument driver a native LabVIEW driver or are you using an IVI driver? IVI would recquire the IVI Compliance Package installed.
