FPGA

[krupa]

I am working on a project were i have to redo a part of the project which was done by another author years ago,as they have lost the software but have the hardcopy.

I would like to know how to add the Enable Drive/disable drive of Mod3 as shown in the pic.Also the Encoder position as highlighted in the pic.Being new to FPGA project i have these basic questions.Pls guide.

Hi krupa,

- those "Encoder positions" are just local variables of some controls…

- all those "Mod3" nodes are properties/methods of a FPGA-attached module and it seems it's dedicated to a motor drive. You need to use the very same module as was used years ago in your FPGA project, then you will get the same block diagram nodes!

Thanks much.

I am using a German version of LV thats why i am not able to understand the properties/methods.I have tried everything by right clicking mod3 but nothing works similar to what is there in the pic.The setup is same just the software is lost,so i am taking care of using the right mod.

Hallo krupa,

es gibt da ja noch das deutschsprachige www.labviewforum.de , falls du so evtl. besser klar kommst! 😄

I have tried everything by right clicking mod3 but nothing works similar to what is there in the pic.

Is it exactly the same module as has been when this app was developed?

[krupa]

Yes i am using the right module which was there during the initial development.When i click the properties of mod3,under category has its name and on the right side of it has no option.

i am using German Version as that is what installed in my lab but i speak,understand only English 🙂

Hi krupa,

I meant you need to use FPGA property nodes or FPGA method invoke nodes related to your module "Mod3"…

[krupa]

Yes i got it.I said,the properties of mod3 is empty.

May i know where i went wrong??

Hi krupa,

with just some images of hardcopies of ancient code we will never be able to help you fix problems with your current code…

Provide more information to have us provide better help!

Just an idea after looking into the glass ball: You forgot to install SoftMotion drivers - Mod3 seems related to motor drives…

[krupa]

I am using NI9505,Mod3 that is used in the pic is motor.

NIDAQ1550f1-latest version: was the driver software installed for it.

[krupa]

I am totally using 3 modules NI9237,NI9401,NI9505 and NI-CRIO-9073.

I guess the driver sw installed is correct.

I am doubting the calibration part for NI9237.During development it was calibrated for half bridge,i have to calibrate it for full bridge now.Could you pls help me with the proper steps for calibartion.
