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.

The schematic diagram of the module is shown in the attachment
