DC bus error reaction settings

DC bus error reaction settings

Hi,

During commissioning of a machine mains fuse occassionally blew when XG31:3 got the signal to start loading DC bus (P-1720.0.150). Configuration is pretty similar to the picture with XCS/XMD/XMS.

After changing "Reaction to DC bus undervoltage" settings from E2026 to F2026, this problem no longer occured. I have no idea why this would have such an effect, so all suggestions are welcome.

We agree with you that this should not have such an impact. For detailed analysis we would need a parameter file in format "all parameters".

@Joonas Are there any news? Is this still an issue?

Apologies for the late reply.

It seems that the changes in the parameter file had no effect; it was just a coincidence. For now, it appears that the solution was to remove the incorrectly sized choke from the system.
