The Bosch Rexroth R911268385 (DKR02.1-W300Z-BE23-01-FW) model is a cutting-edge drive controller used in diverse industry sectors. It benefits from multiple cooling methods, with duct cooling being recommended due to its efficacy in dissipating 1200W of heat with the built-in blower unit. The controller can be used up to an ambient temperature of +45 degrees Celsius without any reduction in drive data. It must be operated with a minimum clearance of 160mm at the air intake and outlet, and used only with approved accessories and motors. Before commencing operation, it must be suitably configured and programmed using the DSM 2.3 software module. It communicates via the SERCOS interface, and can be installed up to 1000 meters above sea level without derating. The R911268385 (DKR02.1-W300Z-BE23-01-FW) operates at a rated voltage of 3x400 – 480V, a rated current of 300A, and employs an auxiliary bleeder resistor.
