Please request your support:

I am currently working on a project to control the position of a three-phase induction motor with the KIT for sensored vector control and I need to know if I have to make some additional adjustments to use the kit with a motor of 1HP (746 W) 220 V and 60 HZ instead of the motor that usually comes with the kit which is 0.25 HP. Then I want to know what? and where ? I must configure the program or the hardware since the program of the code composer simply stops when the voltage of the VARIAC increases when I rise to more than 130 V the program stops but the engine continues to run.


I clarify that I have already modified several parameters of the file "settings.h", like the peak current and the motor parameters.

    1. The motor phase lines are connected in the correct order
    2. The motor encoder lines are connected in the correct order
    3. The number of encoder lines is set in f28xxxxqep.h, to set MechScaler, LineEncoder and CalibratedAngle correctly in qep.h for sensored control.
    4. The motor parameters is set correctly in xxx-Setting.h

    Dear Yamming,

    I clarified that I connected the encoder and the motor correctly, I changed the encoder correctly in the software but still the program continues to stop and an error appears:

    The value is '-151' (0xffffff69). The title is 'SC_ERR_FTDI_OPEN'. One of the FTDI driver functions used during the connect returned bad status or an error.

    thanks for you comments.
