Dear team,
I made a motor driver for 24V and running with f28069 launchpad. I am using lab5a.
I am using two power source 12V for powering driver and instaspin and 24V for Inverter Circuit. Also i made common grounding as i have to measure phase voltages.
I used 270uf 25V electrolytic capacitor for 12v power supply and 470uf 50V electrolytic capacitor for 24V power supply.
I have problem with the motor run. All the parameters identified are also good.
But the problem is when i enable the Run_identity flag to enable the motor control, i check all the voltages being fluctuated with a noise around 500 Khz frequency. (I am using 30 Khz User_Pwm frequency)
Please suggest what could be the reason.
Thanks.
