I don't want to use control unit. I just want to get dc voltage from this basic line module. In that, there are 3 types of Led, 1. Power okay, 1, ready, 3 dc link, 1. power okay led shows green light. 2. ready and dc link led shows orange light. My question is why my basic line module is not providing dc voltage? If any problem, what is the procedure of commissioning of blm? BR Mahmud

The only infeed which you can use without a CU is the 5kW and the 10kW SLM (Smart Line Module). The BLM would be an own Drive Object - including p840 for switch on the BLM (for example it is neccessary to bridge the precharge resistors to ge the complete power).
