DRV8912-Q1EVM: Fault output issue

Hi TI team,

We use DRV8912-Q1EVM to connect the three-way valve for load test. One end of the three-way valve is connected to OUT4/6/7/9 and the other end is connected to OUT3/10/11/12. During the process of controlling the positive and negative rotation of the load, some OUT terminals will report overcurrent or OLD faults, and the fault OUT port is uncertain. What might be the cause of this problem? Is there any way to avoid this problem? Many thanks!
