How do I fix an F7 Saturation Fault code for a DG1 drive?

The saturation fault is the drive looking at a digital signal from the power board that indicates short trip, if the voltage is showing a low level of 0.3V the drive will see the IGBT in saturation or a short. This problem is usually caused internally in the drive so to troubleshoot please refer to the DG1 Troubleshooting Guide: This should help determine if the issue is inside or outside the drive.
