L6390 issue on STEVAL-IHM023V3

Question asked by motor on May 9, 2015
L6390 on IHM023V3 doesn't behavior as expected.
I am using IHM023V3 for 3-phase motor control. The PWM input signal to L6390 is very clean in sinusoidal, and I short HIN and LIN inputs together on purpose. Unfortunately, the output of L6390 with default deadtime setting messed up, and Vabc are far from sinusoidal. I took a further look on Vabc, and Va and Vb in a period are not symmetrical any more. How to fix? Thanks!
