The Bosch Rexroth drive control unit R911289884 (DKR03.1-W100N-BT04-01-FW) is designed for industrial automation applications, featuring a SERCOS command interface and five programmable plug-in slots. It is configured without a bleeder or brake chopper, utilizing a rigid DC bus and incorporates an air-cooling system via a built-in blower. Operating on three-phase AC power at 400–480 V with a control voltage of AC 230 V (power consumption 200 VA), this unit supports digital servo and resolver feedback. It provides a rated current of 100 A, achieves peak regenerated power of 26 kW for up to 10 seconds, continuous regenerated power of 22 kW, and peak current of 71 A. The device is IP20 rated, suitable for operation up to +55°C, weighs 49 kg, and dissipates 900 W of heat. Auxiliary brake resistor support is included; software must be sourced separately.
