The 1070079652 (MPN: DMA 085B 7301-D) is a three-phase automation module from Rexroth Bosch, engineered for cold module control applications. It supports both synchronous and asynchronous motors as well as inverters, and features an RMB/DM type 2 air cooling system within a switch cabinet conforming to IP54 protection. Interfaces include a resolver encoder and CANrho, with encoder resolutions of 20 bits (single-turn), 12 bits (resolver), and 32 bits (multi-turn), supporting up to 4096 absolute revolutions. The module accepts regulated and non-regulated DC link voltages of 670V and 715V, respectively, and delivers a maximum current of 86Arms (open loop) and 64Arms (closed loop), with a 1.25A derating between 46-55°C. Specs also include a 24 VDC current input at 1.35A and an output voltage of 400V. The module operates at 0-45°C, up to 1000m elevation, measures 100mm in width, weighs 11.5kg, and requires adequate air cooling to prevent condensation.
