Posted on May 17, 2011 at 10:15I used ST7FMC1K2T6, to detect zero-crossing during PWM-OFF, when I set the OS[0:2] bit as 000, and the MCRB is configured as the following: #define mem_CCW_MCRB1 ((u8)112) // HDM & SDM, rising BEMF #define mem_CCW_MCRB...
Posted on May 17, 2011 at 10:15Hello everyone, who configured the OSC(0~2) bits of register MCRB to accelerate the current demagnetizaiton successibly? May you share your successive experience? now whether I configure it, the motor run abnornally, i...
Posted on May 17, 2011 at 10:14sensorless control, complementary PWM, mixed zero-crossing dectection method, when dudycle value is equal to PWM period value, why there is still pwm, not all high-level. I set the deadtime 250ns. can anybody tell me?
