Recommmendation for motion control in mid-7604

I got a new mid-7604 recently. So what type of PCI card should I use to control mid-7604 in Labview? Does 6023E or DIO32HS works? Thank you.

Sorry, but I have to add my 2 cents to this thread .
@AK2DM
thank you for suggesting a 73xx device for this purpose instead of a DAQ device
@bighead
apart from the fact, that the 7604's connector is designed to be connected to a 73xx device, there a a lot of functional reasons, why in general a DAQ board is not a good fit for a motion control application. Here you can find some more information about this topic.
Kind regards,

PCMCIA card for motion control

Hi,
I am trying to control a stepper motor through LABVIEW. After perusing through the site, I know that I would need a stepper motor, a corresponding motion controller and a universal motion interface. The problem I have is that I am trying to control the stepper motor through a laptop (which does not have the Parallel Port slot). I am wondering if a PCMCIA card could work (by providing a parallel port to the laptop) or if it would not meet the necessary requirements to operate the motion control through the universal motion interface.
Thanks

It IS possible to drive an UMI interface with a parallel port providing TTL compatible outputs, basically the UMI interfaces are (advanced) break-out boxes feeding the step and direction pulses to a motor driver and connecting feedback signals (encoders, limit switches etc) back to the PC. But in this case, you would have to write your own routines for accelerating and slowing down, as well as evaluating the feedback signals from an encoder or limit switches. There are several manufactures making motor drivers which can be driven via a serial or USB interface, in case you cannot use a NI controller board it will be much easier to use such a setup since the motor drivers usually incorporate at least a basic motor controller providing a set of commands which makes it much easier to control a motor than with doing everything from scratch.

What kind of equipment do i need for motion control

i'm new to computerized actuators, i need to control a stepper motor that can turn both directions and can be controlled by a 0-5 volt sensor. i need to be able to set the targeted volts and have it turn one direction if its reading over, and the other direction if its reading under. What should i buy.

Hey Jaspittman,
I would also recommend the following web site called Build Your Own Motion Control System which will walk you through the steps of what you will need to build your motion system. Also, I would suggest taking a look at the Motion Advisor page if you will be using any 3rd party hardware (i.e. motors, drives, stages) which can be found at the following link Advisors for Motion. These two sites have a lot of helpful information to get you started.

PCI6602 for motion control?

Hi, I am wondering if it is possible to use the pulse generation of the
PCI6602 to control a stepper motor
driver, the problem is that I need aceleration and deceleration in the
pulse train.
I'm using the PCI6602 for event counting (~ MHz), and I need to
synchronize the data acquisition to the stepper motor pulses at a rate
of ~10 KHz. It would be nice to use a single card for both acquisition
and motion control.
thanx,
Stefano

Stefano,
Yes, you could use the PCI-6602 to control a stepper motor. This will require two counters per stepper axis to control the step/dir or CW/CCW lines, or one counter per axis if you only want to move in one direction. You would need to programmatically ramp up the pulse rate to control acceleration. However, since updating the output pulse train frequency is software timed, acceleration may not be very smooth and you risk losing step. Also, you would need to manually handle any pull in moves.
While you could achieve reasonable stepper control with the counter board with some trial and error, the PCI-7334 would probably be a better solution. This controller easily handles acceleration and deceleration and allows you to route the encoder signals over the
RTSI bus to control the data acquisition process.

Using LabVIEW for temperature control with AMREL SPS200-50-A022 power supply

Hi, I hope someone can help me out. I'm an ME undergrad with pretty much no knowledge of LabVIEW. I am working a project which requires a temperature controller. Previously, we were using an SPS120-10 power supply from AMREL and a grad student wrote a LabVIEW VI which performed feedback temperature control. The VI would acquire temperature from a Benchlink which acquire the temperature from a thermocouple. The VI also monitor the output voltage & current and determine the power output and heater resistance from those values. When a desired temperature is set, the VI compares the actual temperature to the set temperature and adjust the voltage/current setting to achieve the desired temperature. The VI was designed to keep temperature deviation to within +/-0.5 deg C. I'm not sure of the data refresh rate, but it's on the order of seconds since the system has a small thermal mass and we're operating in the 800+ deg C range. When we were using the SPS120-10, the device used GPIB for communication with the PC. Due to higher power output demand for the heater, we switched to an SPS200-50, which only has an RS-232 port. First of all, I was wondering if someone could help me modify the VI so that it could communicate with the SPS200-50 through the serial port? In addition, the drivers for the SPS120-10 and SPS200-50 might be different. If modifying the VI to communicate through the serial port isn't enough, I would need to figure out where to modify the VI with the SPS200-50 drivers, which is provided by AMREL. If anyone would like, I can send you the VI files so that you can take a look at the block diagram and tell me where to modify it. I'm still not 100% certain I understand how to read LabVIEW block diagrams.
Please let me know if you need any additional information. Any help would be appreciated. Thanks in advance!

I have looked over your vi. First of all you have to do some changes in the "ARSPS Initialize.vi" See picture.
The best way to check instrument communication is to send the *IDN? Command. The instrument will indentify itself in response to this command. The vi I have included is a labview example. Use this Vi to test your communication. Do not progress before this is working. The VI is also an excellent example on how to set up and close down RS232 communication.
The VI "Tfeedbackpowercontroller-nolvdt-Dinh.vi" looks OK so I guess it will work then your RS232 communication with the SPS200-50-A022 is working
good luck
PS as mentioned before you will find all the RS232 details in the instrument manual
Besides which, my opinion is that Express VIs Carthage must be destroyed deleted
(Sorry no Labview "brag list" so far)

Joystick or gamepad type buttons for motion control

I am locking for buttons to put on the screen that look like a gamepad control. This would be to manually drive and automated peace of equipment around when it goes in upset condition or can't resolve a maneuver. I'm just looking for 6 or 8 buttons arrange in a circle or someting to drive in 6 or 8 different directions. Are there any add-on for LabView 8.0 that would look like a gamepad or something.

Are you looking for a way to imitate a joystick?
I don't know if this is what you're looking for, but you can customize a boolean control so it looks like whatever you want.

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,

Motion control et Labview 6.1

Bonjour,
Je viens d'installer une carte PMC MFX PCI Series 1000 Multiflex Motion Control en remplacement d'une carte isa (incompatible avec les nouveaux systèmes).Un prog correspondant Motion Control gère le déplacement de sondes sur une table 1 axe de chez Schneeberger.
L'ancien système, à savoir Labview 4, Motion Control pour la carte isa, et PCI 6035E (acquisition de données)exécute le déplacement dans un sens , s'arrête, et repart vers sa position initiale dite origine ou home (fait exactement le cycle proposé par le CW demo.
Avec le nouveau système, à savoir Labview 6.1, carte PCI remplaçant la isa, PCI 6035E gère le déplacement aller, mais après arrêt ne reprend pas la position initiale.
Il faut savoir que les résultats de l'acquisition (face avant et création dans fichiers tableurs)n'apparaissent qu'une fois que la procédure de retour du chariot est activée (donc invisible sur le nouveau système et le chariot doit être ramené manuellement avec CW demo).
Aussi, remarque importante, le cycle proposé par CW demo fonctionne avec le nouveau système (activation sous WinControl de la bipolarité PWM avec 1om2).
J'aimerais savoir ce qui peut provoquer ceci dans le diagramme joint (piste sur MCGo Home.vi)
Merci.

BOSCDII16marsfintableau21.vi ‏815 KB

alamarque,
Tout d'abord, je n'ai pas les VI de controle de votre carte d'axes. De plus, la carte de contrôle d'axes en question n'est pas une carte NI, donc je ne connais ni les fonctions, ni l'outil CW Demo.
Le plus simple serait de procéder par ordre.
1. Avez vous des exemples simples de VI Lv mettant en oeuvre votre carte de contrôle d'axes? Si oui, avez vous essayé de les faire fonctionner seul?
Peut être que le problèmes rencontré provient de la configuration de votre carte.
2. Etes vous sur que l'application original fonctionnait bien en Lv 4.1 . La compatibilité est ascendante, et je ne vois pas de raison concernant le non fonctionnement de ce VI.
3. J'ai vérifié les fonctions d'acquisition de la carte NI que vous utilisez. Elles sont rudimentaires, et dans le cas ou elles produiraient une erreurs, vous en seriez directement informé par une Popup d'erreur. Si vous n'avez pas d'exemples pour le point 1, je vous invite à faire un nouveau VI n'implémentant que la communication Motion (Votre mouvement d'aller retour) afin de déterminé si vous êtes capable de faire votre aller retour.
4. Etes vous sur que le jeu de fonction Lv qui vous a servi a piloter la carte Motion ISA, est bien compatible avec votre nouvelle cartes PMC. Je penses que le constructeur de la carte pourra vous éclairer sur ce sujet. Peux être avez vous besoin d'un nouvelle DLL.

LabView for fed-batch control

Does anybody use LabView for the control of bioprocesses, e.g., for
fed-batch fermentations? I am interested in control algorithms for
substrate addition, etc. .
Karsten.

With visa properties/modem line settings you can easily select the line setting you need and watch for the other line to change state. use property write and read.

I don't know how immediate the line will change state but you can measure this yourself with an oscilloscope.

Simple stepper motion control

Hello all, I am completely new to motion control and my head is spinning with all the options so please bear with me, all help is much appreciated.
I am trying to build a control which will perform point to point movement of something like this:
http://www.haydonkerk.com/LinearActuatorProducts/StepperMotorLinearActuators/LinearActuatorsHybrid/S...
It will be moving to a specified point and then returning to the "home" position, holding and then repeating for a number of cycles. The timing of the movement needs to be pretty accurate, each movement cycle will last about 2 tenths of a second. There will be a few parameters that the user should be able to select before beginning the test.
I think I will need to execute this in real time and I am really hoping to do the programming in Labview for no other reason than I like it better than text based. So my question is really what hardware and software am I going to need to get this done? I went through the info on NI's website and due to my lack of background knowledge it was pretty confusing. It looks like as far as software goes it will basically be Real-Time module. For hardware it looks like a controller and a driver. If I had the PXI-7332 controller and the P70530 driver am I good to go? Or am I missing some critical aspect
Also, if any has any good recommendations for some reading on these sorts of things I would be interested in that as well.
Thanks.

Hi Nick,
We've got two basic options for motion control- PC based, or RIO based. These types of questions are actually quite common for support, if you'd like to contact NI. If not, post back and I'd be happy to help.

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.

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.

When will the Ingenia Motion Control Library be available in LabVIEW 2012?
