Hi All,
Installed a brand new Danfoss FC302 which was a replacement for a failed FC300 drive. Copied all parameters from the FC300 to the LCP (Danfoss Drive HMI) and uploaded all parameters to the new FC302 drive. When this was complete and the new replacement FC302 was parameterized, "Fieldbus Fault W34" appeared.
Found some other parameters on the "9 - PROFIdrive" settings that didn't match up.
Noticed that the Profibus communications card (MCA 101 - Option A 130B1100) had a more recent software version on the FC302 "V5.20" compared to FC300's "V5.11".
I Powered down the drive and swapped out the FC300's Profibus card for the new FC302's card and the fault disappeared, with the "9-53 returning to 0000hex".
Has anybody come across this issue before and if so what is the reason behind it ?

- Checked wiring of ProfiBus to drive.
- Checked parameter "9-18 Node Address" - The Node address didn't update after parameters were copied and uploaded from the previous drive. Updated the Node Address, but the fault was still present, the slave was also in error on the plant SCADA systems ProfiBus network.
- Checked parameter "9-53 Profibus Warning Word" what I assume is a parameter for some sort of Hexadecimal language for detecting fieldbus faults on the drive - This parameter was set at 'A001 hex' on the FC302 but set at '0000 hex' on the FC300. The LCP was stuck in "Read-Only Mode".
- Checked all relevant dipswitches local to the Profibus hardware on the drive.
