KDA 2.1-100-3-AYS-U1

The Bosch Rexroth Indramat KDA 2.1-100-3-AYS-U1 from the KDA Spindle Drives series combines the rugged reliability of the Product Model: KDA with precision control features tailored for demanding spindle applications. It delivers a Rated Current of 100 A and operates on a DC Bus Voltage of 300 V, ensuring robust continuous power and wide speed range. The drive’s Speed Command Input of Analog ±10 V interface enables fine velocity regulation, while the integrated Series: 2 design and Design: 1 architecture optimize mechanical stiffness and dynamic response. This unit is engineered for seamless integration into high-performance CNC spindles and indexing tables.

Advanced control is supported via a dedicated Auxiliary Encoder Input for synchronous and auxiliary signals and an Auxiliary Interface: RS-232C serial port for parameterization and diagnostic access. Thermal management is handled by a Cooling Method: Forced cooling by heatsink blower, backed by a dedicated Heatsink Blower Supply: 115 VAC that maintains optimal junction temperatures under heavy loads. The drive’s compact footprint and rugged construction guarantee long service life, even in environments with extended duty cycles. Field-upgradeable firmware and automated fault logging further simplify preventive maintenance and minimize downtime.

With its combination of high torque capacity, precise positioning functions, and comprehensive I/O options, the KDA 2.1-100-3-AYS-U1 is an ideal solution for spindle-intensive machining centers, grinding spindles, and spindle retrofits requiring stable, high-bandwidth control. Its industrial-grade components and proven cooling strategy ensure reliable operation across extended production runs, making it a cornerstone of any high-speed rotary drive system.
