The R911299708 (DKR02.1-W200N-BA08-01-FW) is a Rexroth Indramat DKR series drive controller with an M1-RAC3 mounting accessory, featuring an IP20-rated enclosure. It utilizes an air cooling method with a built-in blower and multiple air-cooling modes, including options for internal, external, or ducted air intake. The unit disperses heat through its integrated heatsink and vents and can dissipate up to 1.6 kW during continuous drive current operation. The controller accepts a power voltage from 0 to 380 V and supports a maximum peak current of 141 A. Switching frequency can reach up to 1.6 kHz, depending on configuration. The device requires a minimum clearance of 160 mm for air inlet and outlet to maintain proper cooling, and the use of a heat exchanger is recommended for operation above 45°C. Additional features include an analog command interface, no internal brake chopper, rigid DC bus configuration, digital servo and resolver motor feedback capability, and a rated current of 200 A. Device installation and operation should follow the manufacturer's technical documentation.
