Dear Support specialists, We have a VFD that been not used for about 11 year, This VFD is designed for drilling Top drive motor. VFD Model # 6SE7238-6FS00-3AD0-Z We changed all capacitors banks, firing board A23 and CUR module A10 By pressing start button we got F002 (Pre-charge fault) and F103 (Ground fault) if we Press start from rectifier section. Reading the error details in r949 shows the following : '001 Removed all thyristors and check them on bench found two faulty and has been replaced. We have the control transformer which is wall mounted at the left side of the container been overheated. Appreciate if any one got any idea what could be the problem with this VFD. Cheers!
