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,
Jochen

Already worked on designing a cnc table to cut sheet materials.
But we don't know enough for electronics. We think a system which is
software driven from pc. So, we look for Wanted Computer Controled
Electronic Cards with Software for Motion Control but we don't know more
which motors, electronic cards and control panel we have to use.
Please help me. Thanks.

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.

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.

Troubleshooting labview for motion control

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,

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.

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.

Solution for Low-Cost Single-Axis Motion Control?

Hello,
I am currently researching the options that NI has available for low-cost linear actuators. I am looking to replace the functionality of a pneumatic solenoid with a linear actuator. I would like to create a system that uses strictly NI hardware and software. The system should be capable of the following:
Push an object with a maximum force of 500LB
Max stroke of 1 foot
Ability to monitor and control the position of cylinder (how far to extend preset)
Ability to stop/reverse the travel at any point along the stroke
Ability to control the velocity of the cylinder (preset)
The parameters for velocity and stroke length (0-12") would be set before the actuator begins to move, hopefully from a LabVIEW operator interface. These would not be changed on the fly. Any reccomendations would be welcome!
Thanks

I suggest first deciding what motor you want to use. After you choose a motor, you can choose a drive.
NI offers two drives - the MID-765x for servo motors and MID-760x for stepper. motors. You can then connect the drive to an NI motion controller via a cable. If the specifications of these NI drives (see manuals) are not compatible with your motor, you can use a 3rd party drive instead. If you use a 3rd party drive, you will need to purchase a breakout box to connect an NI motion controller's signals to the 3rd party drive. NI offers two breakout interfaces - the UMI-7764 for a screw terminal interface and the UMI-7774 for a D-sub interface.
The NI motion controllers that I would recommend are the 7330 (for stepper only), 7340 (stepper/servo), and the 7350 (stepper/servo). The NI-Motion driver will allow you to command the motor to move to specified positions dynamically and monitor the current position. You can also set velocity constraints or set the velocity directly.
You can find more information on all the NI hardware that I have mentioned on the NI Motion Hardware page. This page lists features for the hardware and provides links to product pages (which contain links to the product manuals).

The MID-7604 puts out a lot of noise, where can I get isolated cables for it?

I'm using a MID-7604 stepper motor driver. I'd like to reduce the ground loop noise in the system that I am measuring on my PXI-5152 (through a series of transducers, etc.) by using an optical or transformer isolator for the 68 pin VHDCI cable that connects the motor driver to the computer. Does such a thing exist or are there other methods to mitigate the noise? I'd prefer to have the MID-7604 and the computer connected to the same circuit/I don't really want to buy a gigantic isolation transformer/surge protector just to plug in the MID-7604.
Solved!
Go to Solution.

OlliesCamel,
The devices I'm using are PXI-5152 for signal acquisition, TEGAM 4040B for amplification, MID-7604 to drive stepper motors (which have specifications shown here http://www.sherline.com/stepspec2.pdf) to turn a Sherline rotational stage. The transducers are both Harisonic I30508T 5 MHz 3.5" focus transducers.
I have scanned in a drawing I made up of how everything is physically connected entitled Electrical connections.PDF. Also, the noise I am referring to is the noise that is shown in picture noiseMID7604.jpg. (It is labeled)
For the initial laser noise I'm getting an optically isolated RS232 which should fix that problem. On the MID-7604/7602 stepper power motor drive user guide and specifications it shows on page 13 that a wire should go from the 3 position to the case for grounding. It also shows that it seems to be attached to the shield of the shielded wire. Is this necessary as long as I have the ground connected to the case of the motor or? The way I have it now I just have a separate wire in the bundled/shielded cable that is going to the case but it isn't connected to the shielding itself.
The settings for the amplifier and the PXI are for 1 M ohm impedance.
As you can see, my signals don't have a very large SNR, so any sort of motor noise is problematic, particularly since the noise I've shown doesn't stay in the same place during the test. It tends to move around/be on top of my signals at random times even though it doesn't show that in this particular picture. It is problematic since I'm taking many measurements (20,480 acoustic signals per scan, etc.).
I've tried averaging (256 times) and filtering (10 MHz low pass filter is the lowest I can go), however, the noise still persists a bit since it happens to somewhat fall under the same frequencies, etc. The averaging does help, but I'd like to run the test faster and so eliminating that noise would help me in that regard.

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.

Is it possible to condition a load cell signal with a 1520 SCXI and then use it as the primary analog feedback for a 735X motion control board?

My system
PXI 1052 chassis
PXI 8196 RT controller
Flexmotion 7356 motion controller
Flexmotion 7354 motion controller
6259 M series DAQ
1520 SCXI
1520 SCXI
1314 SCXI frount mounting terminal block
DSM strain gage load cells
Exlar SR Brushless PM motors
Kollmorgen servo star CD series 5 drives
My objective:
I want to measure the force on the load cells with the 1520 SCXI (i.e. excite the load cell then amplify and condition its output) then I want to use this analog (force) signal as the primary feedback for my motion control system (7356 and 7354 motion controller connected to my drives and motors).
The problem:
The motion controller boards (7356 and 7354) can be configured for force feedback control via analog feedback from a load cell. However the boards implicitly expect the load cell signal to be amplified and conditioned with and external signal conditioner rather then using an NI SCXI module. Currently I’m am reading the SCXI signals via the 6259 M seriers DAQ and consequentially have no way to route the signal into the 735X boards for force feedback control. I can use softmotion to control the motors but then I loose the fast PID update rates possible with the 735X boards.
The question:
Is it possible to condition a load cell signal with a 1520 SCXI and then use it as the primary analog feedback for a 735X motion control board?

Hi GG,
Thank you for your feedback.
>create your own external circuitry to amplify the signal.>
True a few op-amps could amplify and filter the signal externally but the performance of such an amateur built system will never match the accuracy and functionality of the 1520 SCXI. That’s why we spent the $2500 for the professional version.
>One thing that you could do is to use a UMI with your motion controller and then wire your signal from your SCXI to the UMI.>
As I understand it the UMI is basically a break out connectivity interface for third party drives. After conditioning and amplifying the analog force signal with the SCXI module the analog signal isn’t available to wire into a UMI. To my knowledge the conditioned signal of the SCXI resides only in the PXI backplane (i.e. there is no physical access to the conditioned analog signal). Can you explain how the UMI could be help here.
Again thanks for your input GG.

Need an Instrument Drive for Elmo motion control products.

Hello,
I am going to use a Bassoon servo drive from Elmo Motion Control to control a voice coil. I haven't found an Instrument Driver for Elmo through my LavVIEW program or on their website. Does an Instrument Drive for Elmo products exist?
Thank You!

Hello JMJ,
Here are my answers to your questions:
1. Is it possible for me to communicate with the Basic Serial Read
and Write example and not develop an Instrument Drive? I see that the
write VISA VI takes a string and converts it and sends it to the
control card and the read VI receives a signal and converts it. Is the
conversion converting from the Elmo language to the ASCII code? If I
don't write an Instrument Drive will I have limited capabilities?You could use the serial example to write your entire program. If you only need a handfull of commands, then this is probably the most straighforward for you to get going. Everytime you use the VISA Write, the ascii values are written on the serial lines and transmitted to your device. Your device reads and interprets these commands and acts depending on what the command is. Some command may change a setting in the instrument. Some other command may actually ask for the instrument to write back some data. In this case, you need to have a VISA Read after the write to be able to read the data into your computer.
2.  I was informed that there is an Instrument I/O Wizard that would
potentially be easier to use and program than an Instrument
Drive.  What is your opinion on such matter? Could I use either or
neither?You can definitely use the Instrument I/O Wizard to help you . This wizard really helps in parsing the data received from your instrument. You can look this tutorial if you want to learn more about it.   You could use either one. I suggest you try both these methods and see which one seems more obvious to you.
3. If I develope an Instrument Drive are all the seperate commands seperate subVIs?
A LabVIEW instrument driver usually has a set of VIs with specific functionality. For example, you will have one subVI that will initializes the instrument. This subVI may send 1 to 5 (or more) commands, depending on what you need to initialize your instrument. You can then have one VI that set's an attritube. This one would only require sending one command.   You can look at this tutorial for developping a complete instrument driver. However, keep in mind that this may not me necessary for your application.
I suggest you first look at what functionality you need. Then take a look at what commands this will require. You will then be able to plan out your program a little better. I also suggest you post all this information on the forum, so that we may be able to help you with more specific details.
Have a great day.
