Hello!

Would it be possible to control a 3-phase motor using the eHRPWM peripheral on the AM3358ZCZD72?

I need all 6 eHRPWM as outputs that can be set individually to different duty cycles and frequencies.

I want to know any solution.

Please inform me.

Thanks and regards,

Hi,

In am335x, each EHRPWM has 2 channels and individual channels can be configured for different duty cycles but with a common frequency as period register is shared across channels.

3 instances of EHRPWM is available in am335x. Hence you can have 6 PWM outputs with 3 different frequencies & 6 different duty cycles.

Thanks Avinash
