A little background at my complex we run power flex 755 VFD's 480V most of them are 361 Amp. They are etherneted to a controller the VFD has a static IP. Also running ver. 7.002 in it. The Controller is a L61 Allen Bradley version 19 We use them to run belt drives. I ran into a problem yesterday, This drive started giving a drive fault code of 13037 which is Net I/O Timeout. I havent ran into this before and the internet isn't giving much help on this issue. was wondering if anyone else has had this issue.
