Please note, ER module 6SN1145-1BA01-0DA1. is 55/71 KW module. As per AutoGen_7731295 post, when only module is tested without load i.e. LT drive modules, getting 600 V DC output supply. When LT drive modules are connected, 4 A fuse links blows. User has checked LT drive modules IGBTs which are ok. Moreover from ER module capacity which is 125 A, 4 A fuse link ast input side is of very low capacity. So I suggested user to increase fuse capacity from 4 A to 16 A which even in case of short circuit definately will not cause any big TROUBLE as you mentioned. Hope this is clear. |
