How do I fix an F41 IGBT Over Temperature Fault code for a DG1 drive?

The IGBT Over temperature fault is the drive performing an I2T trip. When the IGBT is running at a high switching frequency and there is a huge load on the drive, the IGBT junction temperature will rise quickly or cause the junction to brake. The drive calculates what it thinks the junction temperature is and adds it to the drive unit temperature. If the summed temperature is greater than 125deg C for over 1 sec the fault condition will occur. When this fault occurs it typically indicates that the motor was drawing a high amount of current so it would be suggested to verify if the current was high. From there determine if it is the motor or application that is causing the large current draw.
