text: <s>[INST] PowerFlex 700 VC Ground Fault Issue Summary: VFD goes to ground fault and issue is only resolved by replacing the driveWe have an application where a 132 kW motor is installed and PowerFlex 700 VC 400V 260A Series B is being used to control it. We are facing a recurring issue on this application where the drive goes to Ground Fault and after going through the troubleshooting steps we have found nothing so far. We have used the troubleshooting steps described in the following link https://rockwellautomation.custhelp.com/app/answers/detail/a_id/60178 We eventually replace the drives and after the drive is replaced there is such no fault on the drive. This makes us believe that the issue is somehow at the drive end. Could you guys provide us with help regarding some of the extra troubleshooting steps we might look for? I can provide other details as well if you require it. Thanking you all in anticipation. [/INST] Are you saying that after replacing the drive, the problem goes away for some time, but the new drive eventually reports the same fault? You have meggered the motor and the motor leads at 1000V? What was the resistance reading from this test? You have run the drive with the motor leads disconnected from the drive? The drive runs without reporting the fault? What is the motor lead length from drive to motor? Is there any sort of drive output conditioning (load reactor, active filter, etc.)? \\n </s>
