The R911286288 (DKR04.1-W400N-BE33-01-FW) is a Rexroth Indramat drive controller engineered for air or built-in blower cooling. It features a rated current of 400A, operates without a bleeder (rigid DC bus), and supports digital servo and resolver feedback. Communication is established via the SERCOS interface. The device operates with an AC 230V control voltage (±10%) and delivers a control power of 300VA. It sustains continuous currents of 210A at 4 kHz and 150A at 8 kHz, with a peak current of 282A. Thermal dissipation is rated at 2,500W and 1,800W for continuous operation using an air channel coolant. The unit weighs approximately 150 kg and functions within an ambient temperature range of +5°C to +45°C, up to 1,000 m altitude. Firmware must be ordered separately.
