  • VI quadrature encoder does not work after programming of FPGA

    I'm rather new on the MyRIO, and I work on the motor of the MyRIO and read control in a quadrature encoder at the same time. Programmed individually, the two pieces of work at Marvel, but once I have combine them and try programming, control of motors not to not work signals, but the reader encoder does not work. I use the Express VI for the LabVIEW quadrature encoder reader, and I produce four stepper motors signals using FPGA.

    It seems as if the encoder is disabled when I program the FPGA with my code, because if I have two parallel loops, one for the reader encoder and the control of step motors, if I stop the loop of step motors, the encoder works immediately.

    Is there something simple that I'm missing?  Any suggestions would be greatly appreciated!

    Thank you

    I realize now that my last answer could have been confused and not useful to someone else who may come across the same problems later.

    Here is how I solved the problem I've had:

    I had to derive Boolean expressions for an encoder quadrature (essentially to create my own) and then used the outputs (UP, DOWN) to increment/decrement a counter using the conditional statements. Then, I stored the value of direction in a flip flop implemented using two conditional statements of T/F in series and connected to a shift on the edge of the loop register.

    It was all able to be implemented in a single cycle timed Loop, and then I managed to place in the same loop that I used to control stepper motor.

    In this way, I could have a VI collected in a Bitfile and could be programmed to the FPGA.

    Hope this is clearer!

  • How to read a quadrature encoder, using a PCMCIA card from 6036E?

    Hello

    I 6036E PCMCIA card and I want to read a quadrature encoder.

    I must not use the z index.

    My version of Labview is 8.5.

    What should I do?

    Hello

    Card PCMCIA-6036E has a STC chip that does not support the encoding position because there is no support of Z. It must be resolved in the software and using the edge counting.

  • Erratic counting quadrature encoder

    Hello

    I try to use LabVIEW 9.0 and an acquisition of data USB-6212 for measuring angular displacement of rotating quadrature encoder (digital model we E2) attached to a linear actuator based on the stepper motors.

    With the help of the VI linked to below and the default PFI pin on the acquisition of data, I can get the Angle of the VI to change, but with two issues indicator.

    http://forums.NI.com/attachments/NI/170/144774/1/QuadratureEncoderM-series.VI

    1. the only way I can assure you that the Angle indicator remains at a constant value with the VI running and the stepper motor moves do not is to turn off the power to the encoder.  In other words, when the 5V power is provided to the encoder, the Angle indicator sometimes remains constant at a certain value and sometimes increases, even if the motor step does not move.  I added a waveform table that displays the Angle to see more easy output.

    2. with the engine not to not pass any if she moves hourly or counterclockwise, the angle indicator only increases (counting).  Changing the direction of engine displacement does not decrease the angle.

    I checked the DAQ pins I use: PFI 3, Z = A = B = 11 PFI with ctr and PFI 4 1.  I tried both ctr0 and ctr1 with the same results.  I used a multimeter to check the outputs a, B and Z on the encoder to output with the motor step-by-step to displacements of various populations, and I'm getting ~ + 5V sometimes and ~ 0V sometimes telling me that the encoder, which is new, seems to move from high to low.

    This sounds like the kind of behavior that may be caused by noise in signals?  If so, who should not have something to do with the Angle only, correct?  To get the Angle to reduce, should I change something in VI?

    I thank you very much for any assistance, you can give.

    Hi Mike,.

    From what you describe, I feel the symptom of the meter backwards never is a side effect of the issue where the meter continuously counts up while in not moving.  This really looks like a noise problem, and there are a few small but noticeable spikes in your graphics HAVE you provided.  Basically, as long the (Source) Signal led B Signal (to THE), then the meter progressive count.  This is for X 1 coding, which I assume that you are using.  Look here Figure 5, in virtue of the X 1 section for how this encoding reads your signals of encoding:

    Your connections you describe are correct, so it'll be a matter of getting rid of the problem where the meter is incremented on its own which I believe will solve your other problems.  Take a look at these links to see if adding filters on the internal counter inputs to the card allows the measurement: Activate the digital M series filtering  allowing digital filters for TIO Debounce NOR-DAQmx devices

  • quadrature encoder synchronize the sample

    Using a USB-6251 housing measure a quadrature encoder, I will determine the angle that external discrete changes state.  I tried to connect the unobtrusive to a DIO of entry and using code CVI PC read the angle of the encoder, when the state change occurs.  The problem is the lag time of the PC code that adds up to 4 degrees (with a variability) to the measured angle.  An ideal solution would be to trigger a measure in a buffer in the USB-6251 housing when the State of the discrete changes, then read the value in the PC at a later date.  Is this possible with the USB-6251 housing?

    Thanks Adam,.

    I solved my problem by using this idea with the addition of the use of sampling buffered and discreet as a trigger.  Engaging the material task also seems to be a good idea, but may not be required.

    The installation code looks like this:

    Start a way to encode on the counter 1 to control the angle of the label sensor PNP edges
    status = DAQmxCreateTask ("PNP Rising edges", & pnpTaskHandle);

    strcpy (chanString, devName);
    strcat (chanString, "/ ctr1 ');

    status = DAQmxCreateCIAngEncoderChan (pnpTaskHandle, chanString, "", DAQmx_Val_X4, 1, 0, DAQmx_Val_AHighBHigh)

    DAQmx_Val_Degrees, 4096, 0,0, "");
    sprintf (chanString, "/");
    strcat (chanString, devName);
    strcat (chanString, "/ PFI1");
    status = DAQmxCfgSampClkTiming (pnpTaskHandle, chanString, 1000000, DAQmx_Val_Rising, DAQmx_Val_ContSamps, 10)

    (0000);
    If (status<>
    DAQmxGetErrorString (status, errString, 1000);
    DAQmxTaskControl (pnpTaskHandle, DAQmx_Val_Task_Commit);
     
    Start the task
    status = DAQmxStartTask (pnpTaskHandle);
    angleTaskStarted = 1;

    Read the value of looks like this:

    status = DAQmxReadCounterF64 (npnTaskHandle, DAQmx_Val_Auto, 0, npnEdgeArray, 1000, & npnSampsRead, 0);

    Some DVD players do not use the Windows default drivers so check with the manufacturer of system and

    How that could happen?, if the file has been changed in one of the programs of Windows, but hot downloaded/sauvΘs properly icloud could happen.

    How can I restore it? Tell us where you want to restore from and we (me or anyone else if I do not know this place enough) will tell you how to restore.

    If you do not know where to restore from - start to go to icloud.com - login and go to settings, under Advanced there is some recovery, including the file recovery options - see if that helps. Good luck and best wishes as well.
