    Re: DIY AC Servo Drive - ATMega based

    Hi Mahai
    U r right on step missing but when recalibrate the servomotor it rotates for calibration. This is problem .
    I feels don't rotate the motor at calibration.
    When any drive gets commutation signals from sensor r encoders It never rotates for phase calibration .
    It's only suggestion .
    Ur all efforts for this drive are appropriateing .

    Hello Shabir!

    I have an idea it can easily be implemented. Before starting motor initialization, we can get the encoder PPR, and then, after initialization set the position back. How does this sound to you? I can easily implement this, and I'll do it this evening.
