TMDSHVMTRINSPIN: Which parameters can I change while fulfilling requirements of User's parameters using hvkit?

What are the exact error codes that you saw? What aspects of the HW/SW are you trying to change?

Jason Osborn

I was trying to implement lab 21 on my own motor, after satisfying with no User_errocode existing by adjusting IQ_Full_Scale frequency, voltage, current and USER_PWM_Freq. I enabled the system and I saw the value of speed, torque, VdcBus kept changing in a wide range, I wondered am I setting some of the value wrong or any restricts I did not satisfy, which results the failure.

Incorrect offset values are a big sign that something in the hardware setup is wrong. Unless setup/configuration code was changed, it's not usually a parameter issue.

• What are the states of the controlCard switches? Verify these states against the TMDSHVMTRINSPIN HW user's guide document, located in either controlSuite or C2000Ware Motor Control SDK. Location:
  • 
    
    
• Is power hooked up correctly?

I did't notice these files until you answered and I took a glance at the material that you pointed out, it seems that I overloaded and no other problems found. I was implementing the kit on a 1.5kw IPMSM motor, should I change the motor to less than 750w? Another question is that the system was energized by 220V AC power, should I input 15V DC  external power simultaneously with the 220V AC power? Looking forward for your reply and if the answer is yes, I am gonna change the motor and test on it a few days after.

Hello,

Ipost up the picture of the hardware, I thought I set the hardware up correctly.

I changed the motor and tried, the result was the same. I also wondered that I succeeded running the motor with the GUI Composer, but with CCS the motor cannot run successfully. Does that mean the hardware setup was correct but something was wrong with the parameters or the program itself?

Thanks.

If the motor succeeds with the kit's GUI but not in CCS, the most likely problem is that the CCS project is not correctly set up. What is the .projectspec file you're using?

D:\TI\motorware_1_01_00_18\sw\solutions\instaspin_foc\boards\drv8301kit_revD\f28x\f2806xF\projects\ccs\proj_lab21

I used the project following this directory. I wanted to implement lab21 on my motor, but I couldn't find lab21 under hvkit, so I used the proj_lab21 under this directory. Maybe I used the wrong one. If so, could you please tell me the correct directory, where lies the project that I should use.

Thanks.

Is there any existing project I can implement with HVKIT to realize high-frequncy signal injection method?

Thanks Jason for your reply.

I got some other questions that I want to consult. From the table listed in lab document the hvkit seems to have the capability to run high frequncy injection, but why there is no existing project for it like drv8301kit? Since I have TMS320F28069MPZT F2806x ISO controlCard with hvkit, does that mean I can implement any FOC and MOTION lab project, which listed under the directory of hvkit_rev1p1 such as lab11a? Looking forward for your reply.

Thanks.
