Thank you Brian,

A small favour more needed. The file you attached is based on the labview 2015 version. The version currently available with me is the labview 2014 version. So I would really appreciate if you could please attach the 2014 version of the file.

Thank you soo much for your support.

I didn't get a chance to try it out, but here is the same code saved for 2014.

Thank you..

What do you mean by didn't get a chance to try it out?

[ammarqs]

I get this error after I load the project.

Brian,

Also i am getting a few errors while opening the testbench.vi file. some files are missing or it is not able to locate them.

I don't have a 2014 test machine on hand to test it out right now is what I meant.  It is tested in 2015.  I left the 9607 target, and added the 9606 like you have there.  I forgot the 9607 is not supported in LV 2014, so just go ahead and delete the 9607 target out of the project. 

Go ahead and link to the new location.  Apparently those VIs are absolute linked and not relatively linked, but by accepting the new location that problem should go away.

This is the error i am still getting related to some missing files in the SVPWMtestharness.vi file.

It also says that there is a tick count missing.

In your previous given file, a month back, i entered the values you gave me and still the induction motor gives a jump start and and then turns off. Also my IGBTs get heated up quickly and the system shuts down.

Looking forward for your reply.

Thank you again.

For the tick count VI just delete it and make a counter that each iteration counts up by one.  It is for a quad encoder so if youdon't have one you can just delete the entire quad encoder.  The reason the SVPWMTimingAlphaBeta_gen.vi is broken is because that VI is created using IP Builder.  IP Builder annoying only compiles for a single FPGA type.  In this case I sent you the one generated for for the 9607 target.

Normally to fix it you need to bring the SVPWMTimingAlphaBeta_src.vi into the IP Builder, creates directives, then build the code.  I tried in 2014 and it errors out for some reason.  I don't really have the time to look into it right now so instead I moved to using a SPWM algorithm instead of SVPWM.  Hopefullt that is acceptable for now.  The updated code is located

Thank you,

Fortunately, for some reason the SVPWM file you sent started compliling without any previous errors. I didn't have to open the SPWM file yet.

Looking forward to burn it to the FPGA and start monitoring.

Will keep updating you with the progress.
