The Bosch Rexroth drive controller R911278624 (DKR03.1-W100N-BE84-01-FW) is an industrial unit with a mass of approximately 49 kg, designed for operation within ambient temperatures of +5 to +45°C and installation altitudes up to 1000 meters. Storage and shipping are supported in temperatures from -30 to +80°C. This controller operates with a power supply of AC 3 × 400–480 V and a control voltage of AC 230 V at 50–60 Hz. It delivers between 22–26 kW output with continuous currents of 60–71 A, dependent on the frequency setting. The base unit is DKR03.1-W100-B, featuring multiple plug-in slots, a SERCOS communication interface, and supports digital servo and resolver feedback. The protective design is rated at IP20, employs an air-cooled method with a built-in blower, and supports a maximum auxiliary brake resistor power of 150 kW·s. The device is supplied without an integrated brake chopper and the firmware is ordered separately.
