The Bosch Rexroth Indramat KDA 3.1-050-3-LQI-W1 from the KDA Spindle Drives series and manufactured by Bosch Rexroth Indramat delivers precision spindle control with a Rated Current of 50 A and a DC Bus Voltage of 300 V to support demanding machining tasks. This compact drive features an integrated Speed Command Value via SERCOS - Interface for seamless synchronization in multi-axis systems. Built on the proven Design 1 architecture of the KDA family, the unit integrates a robust Product KDA core optimized for rigidity and dynamic response. Its versatile configuration supports both automated production lines and custom CNC applications.
Reliability is reinforced by dedicated thermal management and encoder interfaces: the drive is Forced Cooled by Heatsink Blower drawing power from an AC Supply Source for Heatsink Blower of 220 VAC to dissipate up to the maximum continuous output without thermal derating. Precision feedback is handled through an Aux. Encoder Input for 1V Sinusoidal Enc., while position and speed loops are closed via the onboard Aux. Interface Incremental Encoder Output. The hardened electronic design ensures stable operation across a wide ambient temperature range, minimizing maintenance intervals in industrial environments.
Installation and commissioning are streamlined with standardized mechanical and electrical connections, making the KDA 3.1-050-3-LQI-W1 an ideal drop-in upgrade for existing Bosch Rexroth Indramat infrastructure. Its balanced footprint and service-friendly layout reduce cabinet space requirements and facilitate quick access to modular components. Backed by global support from Bosch Rexroth Indramat, this spindle drive offers a future-proof solution for high-precision milling, turning centers, and high-speed drilling applications.
