The Bosch Rexroth drive controller MPN R911281703 (DKR02.1-W300B-BE11-02-FW) is engineered for integration with ungrounded three-phase power systems and utilizes a serial interface link for PC communication. It features two analog diagnostic outputs (±10V, 4mA load) and supports motor feedback via digital servo and resolver feedback, connected through a proprietary cable. The device incorporates a bleeder resistor rated at 720 kW for energy dissipation, with cooling provided by a built-in air blower. The SERCOS interface enables command communication. System start lockout is managed by applying 20–30 VDC. Installation requires mounting on a back wall with threaded holes. Firmware is stored in an EPROM within a software module identified by a rating plate. The controller supports a current rating of approximately 300A.
