The Bosch Rexroth MPN R911200934 (RD52.1-4B-075-D-F1-FW) is a drive control unit utilizing a 52 line code and field-oriented vector control, with current filter feedback accessible at the U6, V6, and W6 terminals. The unit features a rear-cooled power section via a plug-through cooler and supports both induction and synchronous motors. Key performance parameters include 0.3 ms torque rise time, 0.1 ms current cycle time, and the ability to sustain a 170% overload for up to one second. It is rated for 3 x AC 380-480 V operation and delivers 75 kW rated power as a converter with a built-in brake chopper. AL electrolytic capacitors serve as DC link capacitors and have a recommended storage period of up to two years at temperatures below 40°C. Compliance with national EMC regulations is required, and installation should minimize proximity to remote control or high-frequency radio equipment. Only qualified personnel should handle the device due to possible exposure to hazardous voltages.
