TMDSHVMTRPFCKIT: Connection failed with PC

TMDSHVMTRPFCKIT: Connection failed with PC

Part Number: TMDSHVMTRPFCKIT

I have done everything that you said, but it is still not working. And regarding the mentioned oscilloscope, i would like to emphasize that i did not use any oscilloscope at all. So i could not be the reason of the damage.

Is there any other suggestion what could be the problem?

Regards,

Bence

    What controlCard are you using? Isolation one or Non-isolation one?
    What JTAG emulator are you using? On-board one on hv-kit, or one on controlCard?
    What error is reported if a failed connection with PC?
    Did the issue come up at the first time using? Or appeared after you have used the hv-kit for some time? What process did you do before the issue appeared?
    Did you try the USB port of your PC to connect other devices to verify the port?

    As we mentioned before, could you please have a more detailed information for Q4 and Q5? And please refer to the section "Installation FAQ" as below link to check the on-board emulator. You might follow the steps to repair it if the question is from the emulator.
    processors.wiki.ti.com/.../XDS100

    And the section "Troubleshooting FAQ" in below link
    processors.wiki.ti.com/.../XDS100

    If you ensure the power supply to board and controlCard is good, and the failed question still had after you did the process in above link, maybe, you have to contact your distributor to look at how to process this damaged kit since it's good to be used for some time on your side before.

    Just wanted to check in and see if there is an update from your side, I haven’t heard from you for a week, so I’m assuming you were able to resolve your issue. Please let me know if you have any questions. We would like to close this thread if no any further questions. Thanks.

    Sorry for the delay.
    Q4: The issue appeared after i have used the hv-kit. The steps what we have done:
    • Jumpers [Main]-J3, J4 and J5 were installed. Jumper [M3]-J5 was not populated. Jumper [Main]-J9 was populated.
    • Banana plug cord was populated to [Main]-BS1 and BS5, because we would like to use AC mains power
    • Control card was populated
    • Connected the 15V DC voltage
    • Turned on [M6]-SW1 ---> [M6]-LD1 and LD1 on the controlCard were lighted
    • We have connected the USB cable and the [M3]-LD1 turned on
    • We ensured about the right settings of the control card
    • We have setup the Matlab/Simulink model (external mode)
    • After the setup: The green LED1 lighted and LED3 was blinking on the control card, indicated that the code was running
    • Then we connected the AC Mains, and tried run the model again, but the motor did not move, so we have the setup disassembled
    • Next day: we started to do the steps again, when we plugged the USB in the hv-kit, the [M3] LED1 was not lighting, and the connection was not possible anymore

    Q5: The usb port of my PC is fine.

    We were still not able to resolve the issue.

    Did both controlCards have the same connected question? It seems like the HV-Kit and a controlCard worked well when you began to use the kit. Maybe, you might only power on 15V first and not turn on the AC power supply, to check and ensure the control algorithm works well with right PWM output and ADC feedback signal. And you might follow above links to check if the on-board emulator or controlCard is damaged. Or if you locked the flash of controlCard with error password on the controller.

    As mentioned and replied to your last thread. You have to contact your sales to deal with this if the kit is damaged.
