Dear all,

We have G120 drive for drag chain conveyor application. Motor full load current is 14A. P0640 is set at 13A. We get overcurrent fault sometimes rarely. But we dont find the trend in Wincc for motor current to be more than 13A during fault. Why?

Split from Sinamics G120 fault F7802.

I can think of two possible reasons. First, you are logging smoothed current. Second, you had bad luck and the WinCC with its slow logs didn't  hit in the right moment.

Hi Sir,

Then should i use r68[0]- Actual Current smoothed??
