text: <s>[INST] Getting Fault code 9 followed by Fault code 5 Summary: Can a blip current spike cause a drive to get Over Volt fault ?We have 150 HP motor that keeps getting a fault code 9 (Transistor Over temp) then followed up with a fault code 5 ( Over Volt). We put a Fluke metering on the drive while it was running and took samples of Current , Voltage on each phases. We saw we would get a blip of a current spike then the drive would follow up with a voltage spike and fault with a fault code 5. This would happen when the drive was running but not under load (cant bottom profiler knives not processing product at the time) and moving into position for the next cant set. So we are trying to figure out if we have a drive going bad or a motor torque issue. By the way when it faults it's set fault to coast and free spins for about 7 minutes. Any thoughts Drive or motor..... [/INST] What drive is this? How is the drive configured? Vector with feedback? Do you have a dynamic braking resistor? What speeds does the code 9 fault happen? \\n </s>
