Now my controller encounters a problem Is there anyone who can help me, the specific situation is the same motor I can get a larger torque with the controller I bought, but I do it relatively weakly, at present I have checked the PWM waveform, suspecting that the modulation algorithm has been used, but when looking at the PWM waveform, only the upper bridge arm will be open irregularly when the load is large, but there is no long shutdown, very strange, it is said that if the modulation has been used, there should be a normally closed or normally open, I will upload a grabbed PWM waveform later, thank you
