The Bosch Rexroth R911321586 (DKR04.1-W400E-BA04-01-FW) is a drive controller engineered for precise motion control in demanding industrial environments, such as machine tools and printing machinery. Operating on a 50-60 Hz frequency, it accommodates a control voltage of 300 VA and provides heat dissipation of 2500 W via an integrated blower. The unit supports digital servo and resolver motor feedback, has analog command interfaces, and a rated current of 400 A. It functions reliably within an ambient temperature range of 5°C to 45°C and weighs approximately 150 kg. Expansion options include CLC link and analog signal interface cards. The controller uses ESM02.3 firmware for parameter storage and transfer, and features an external bleeder with brake chopper and rigid DC bus for safety and performance.
