The Bosch Rexroth Indramat KDA 2.1-100-3-DYI-W1 is a high-performance spindle drive from the KDA Spindle Drives series, engineered by Bosch Rexroth Indramat for demanding industrial automation tasks. This panel-mounted unit features an Enclosure: IP20 rating that protects internal components from solid debris while allowing efficient heat dissipation. Designed for Phases: 3-phase operation, the drive delivers a Rated Current: 2.1 A with a Peak Current: 4.2 A capability to support transient torque demands. Weighing Weight: Approx. 6 kg, it balances structural robustness and ease of installation. The compact form factor and Mounting: Panel mounting style enable seamless integration into standard control cabinets.
Performance excellence is achieved through an advanced Cooling Method: Internal fan cooling system that maintains optimal thermal conditions under continuous operation. The drive’s Control Mode: Digital (DYI option) offers high-precision speed and position regulation via a Speed Command Value: Digital 16-Bit Parallel interface, enhancing motion control accuracy. The DC Bus Voltage: 300 V rating aligns with common machine-tool power architectures and the Voltage Class: 100 V designation ensures compatibility with medium-voltage DC bus systems. A robust Connection Type: Terminal connector provides secure electrical interfaces, while Overload Protection: Integrated electronic protection detects and isolates overcurrent events to safeguard both drive and spindle motor. An Aux. Encoder Input: With Auxiliary and Synchronous Inputs (Due to AS 35 and Speed Command Value = A)Aux. Interface1 further extends functionality for synchronous motion tasks.
Engineered for reliability, the KDA 2.1-100-3-DYI-W1 employs a rugged construction and precision electronics to deliver consistent performance in harsh environments. Its Dimensions (h X W X D): 390 x 105 x 265 mm profile optimizes space utilization in control panels, making it ideal for retrofit and new-build installations. The unit’s integrated features support applications such as CNC milling spindle drive roles, C-axis contouring on turning machines, and high-resolution spindle positioning for tool-changer indexing. Ultra-fine speed control down to micro-rpm levels enables superior surface finishes in micro-machining operations. When combined with Bosch Rexroth Indramat ecosystem components, this spindle drive forms a cohesive automation solution for precision manufacturing.
