Siemens 6SE7090-0XX85-1DA0 Control Module CUR For Infeed And Infeed Regenerative Feedback

Siemens 6SE7090-0XX85-1DA0 Control Module CUR for infeed and infeed/regenerative feedback units is a spare-part control module designed to replace CUR units in legacy Siemens drive systems that manage the infeed and regenerative feedback paths. The manufacturer markets it as a replacement part and specifies that the associated software 6SW1701-0DA14 is required (T434E). Siemens also notes a migration path to LV SINAMICS, reflecting the system’s evolution from older hardware. This CUR module is used with drive configurations such as SIMODRIVE 611 digital and Simovert Masterdrives, where it serves as the control component for the infeed/regen units within the drive architecture. Because it is sold as a dedicated spare part, it appears in catalogs and repair listings as a compatible substitute for failed CUR modules in these older equipment families. When considering a replacement, buyers typically match this exact model to ensure proper software alignment and to preserve the original infeed and regenerative feedback behavior of the legacy system.
