The Bosch Rexroth Indramat DKR02.1-W300Z-BE11-02-FW drive controller is a robust member of the DKR Drive Controllers series, engineered for precision motion control in applications such as machine tools, printing machines, and handling systems. It delivers a current rating of 300 A and employs a built-in blower for air cooling. Communication with AC motors is handled via the SERCOS interface, ensuring real-time, deterministic command transmission for accurate control and synchronization.
Designed with an IP20 protection rating, the DKR02.1-W300Z-BE11-02-FW is intended for installation within an IP54-rated control cabinet to safeguard against dust and reactive contaminants. The basic unit incorporates a power rectifier and five PCI slots, supporting the integration of a DSS 02.1M command interface card. Feedback is managed through a combination of digital servo and resolver feedback modules, delivering high-resolution position detection. Technical identifiers include Design Version: 1 and Line Series: 02, while the nominal current is specified as approximately 300 A. The bleeder resistor configuration is currently Undefined, allowing for tailored braking energy management. At 104 kg (excluding bleeder resistor, mounting kit, and blower), the controller balances stability with manageable footprint.
Built for continuous operation in ambient temperatures from +5 °C to +45 °C and up to 1000 m above sea level, this drive controller offers maintenance-free performance when installed per Rexroth Indramat guidelines. The integrated bleeder resistor can dissipate up to 240 kWs of braking energy, while the 24 VDC blower maintains optimal thermal conditions under heavy load. Firmware is available to order separately, enabling customization to specific control requirements. Backed by a one-year warranty, the DKR02.1-W300Z-BE11-02-FW ensures reliability, durability, and high efficiency in demanding industrial environments.
