The Rexroth R911297203 (DKR05.2-W500F-BE12-01-NNSN-FW) is a DKR Series digital drive controller engineered to regulate and monitor electric motors such as the 2AD series with output ratings between 115 and 375 kW, while its operational limit is set at 165 kW. This device supports a rated current of 241 A at 4 kHz and 181 A at 8 kHz, with peak capacities of 241 A and 217 A at 4 kHz and 8 kHz, respectively. The controller includes a digital encoder, supports servo and resolver feedback, utilizes a SERCOS command interface, and is equipped with a door-mounted main switch. It incorporates a forced-air cooling system via an integrated blower and has a power dissipation of 6.2 kW. The unit does not support a brake chopper (floating DC bus configuration) and requires separate firmware. The device features a pebble gray cabinet with a lock designed for a 7 mm three square socket wrench and has a mass of 550 kg. Professional installation and operation are recommended.
