I want to make two PWM module that the counting direction is reverve as picture bellow.
- ePWM 1 is start counting Up-down-Up,
- ePWM 2 is start counting at Down-up-Down.
I set the PWM module syncronized = zero, without any Phase shifted (TBPHS=0). However, i can not get the desured result.
with kindly, need assistance for set this ePWM matter.

You have set the counting mode to 'Up-Down' in both the ePWM Block Parameters. Changing that might help you get the desired result.

Hi Arifin,
Although in the block parameters of ePWM block you have specified 'Counting-Mode' as 'Up-Down' for both ePWM blocks but the parameter 'Synchronization action' is different for both the blocks.
Now as per the snapshot of Block Parameters for 'ePWM4' block because 'Synchronization action' is 'Set counter to phase value specified via dialog' another parameter 'Counting direction after phase synchronization' is enabled.
The value for 'Counting direction after phase synchronization' is 'Count down after sync' so I guess this is the parameter which is forcefully starting count from down. So if you set 'Synchronization action' to 'Disable' then both plots might become identical.
You can refer the following documentation links for more details about these parameters:
Hope it helps!
