The Bosch Rexroth MPN 1070085639 (DMA 45A 7301-D) is a three-phase inverter module designed for industrial automation, supporting precise operation with a 12-bit resolver encoder for accurate position feedback. It interfaces with synchronous motors (SF, SR, linear), asynchronous motors (DU, standard), and built-in motor types. The module features a modular construction with dimensions of 50 mm width and 521 mm height, accepting a 670/715 VDC dc-link voltage, typically derived from a three-phase AC 3 x 400–460 V supply. The 24 VDC input current is 1.32 A. Integrated cooling is provided by two internal fans with ambient air flow. Configuration and parameterization are executed through an RS232 port using the DSS-D system.
