TMDSCNCD28379D: EPWM5 and EPWM6 not working

Hongmei Wan

Part Number: TMDSCNCD28379D

Tool/software:

Hi,

I am using TMDSCNCD28379D and measured all PWM signals. PWM1,2,3,4 are working as expected but PWM5, 6 have no outputs. Do I need to do anything else for this two PWMs?

Thanks,

Hello Wan,

It should be configured the same way as for the first four ePWM modules. Could you share your configuration to see what could cause an issue, please?

The configuration is completely same. The only difference is that the frequency is different. The frequency of PWM1,2,3,4 is 200kHz and the frequency of PWM5, 6 is 150kHz. When the frequency is same, everything is good.
