Hi,

When does the PWM trip occur?

We can increase Iq ref, speedref, etc in PMSM FOC upto 1.0 pu safely right ?

Hi Dijo,

Are you referring to a particular kit or in general?

Hi Gautam,

I am using TMDSHVMTRPFC kit. I need to know the maximum duty cycle that I can apply to my PMSM motor 200VAC, 200Hz, 3000rpm.
So can I vary my input parameters upto their maximum (1.0) pu or is there any hardware consideration I should take care of ?
I am new to this field, so if you could explain in general terms ,it would be great.

Regards,
Dijo Paulson

PWM tripping is determined by Trip Zones ie TZx pins. You can configure them in either CBC (cycle-by-cycle) or OHT (one shot trip) to trip the ePWM. Please go through the TRM/Userguide to get more info.
