In the use of IKCM20R60GD IPM module, Hin (A), Lin (A) as A group of drivers, the main circuit is connected to A coil 1, Hin (B), Lin (B) as A group of drivers, the main circuit is connected to another coil 2, Hb, Lb.
Now the problem is that if I only add drivers in HIN(A),LIN(A), the corresponding two switches can operate, then coil 1 has A responsive voltage;If I only add drivers in HIN(B) and LIN(B), the corresponding two switches can also operate, then there is a responsive voltage on coil 2;That's normal.However, I added drivers HIN(A),LIN(A), HIN(B) and LIN(B) at the same time, so the four switches could not work normally at the same time.That's the problem now.
