Hello Simatic Manager, First, you should havea copy of the GH3 manual for chassis components: http://support.automation.siemens.com/WW/view/en/34474944 Turn to page 76 and you'll see that the DC link is only available at DCP and DCN. Page 77 says that the connecting thread is M10 or M12 depending upon the size of BLM being used. From this connecting thread you will have to use ring cable lugs (crim-on wire lug) to each of the tiers of drive sections. The connecting cables are not standard offerings in the PM21 Catalog for Sinamics. Your local Siemens office may provide additional information from other Siemens divisions for connections. In the PM21-2008 turn to page 3/193 for DC link adapters for Booksize modules.The 6SL3162-2BM01-0AA0 adapter is rated for 240A; however, the Single Motor Modules (see page 3/148) are only rated for 200A each. You'll have to group three of the 60A SMM's together and figure out where in your cabinet the remaining MoMo's should be placed. I believe Rattal makes copper bus materials for coupling the 600 Volt DC link from one area to another. This way the DC link can maintain insulation and provide a parallel feed similar to what might be used for power transmission (e.g., antennas). Hope this helps... |

As an alternative you may want to think about the pre-engineered SINAMICS S120 CM. These Cabinet Module linups feature a copper DC link busbar that runs along the top of the cabinets and have copper links for connecting the cabinet modules together. For a common DC bus system as you mentioned you would have one cabinet (one part number) for your Line Module and then you could combine a few more cabinet modules for your Motor Module groups. Even the Motor Module cabinets are pre-engineered sections. Each motor module would have a drop from the DC link busbar and you could even add an option with a disconnect and pre-charge if you wanted the capability to isolate one of the motor modules from the DC bus. http://www2.sea.siemens.com/Products/Drives/Low+Voltage+AC+Drives/SINAMICS-S120-Cabinet-Modules.htm |
