In this setup, a jumper wire is used to connect the ePWM1A output pin from Board 1 to the External Sync input of Board 2 after building the control processes on both boards and the saturation threshold is set to 1.5701.
However, in external mode, the rising edges of the PWM signals still occur at the same time as shown on the scope I’m not sure if this issue can be solved.
