Simovert Master Drive Problem

Muneeb Khan Posts: 3 Rating: (0)	Sir, I am facing a problem with 2.2MW 12 pulse master drive. It trips on f028. I have checked out the supply, connections of the supply. Every thing seems to be ok. Also the fault is not very much frequent sometimes it occurs after 1 or 2 days and some times after a week. I am still not able to sort out the problem. Please guide..........
