KDA 3.1-150-3-DQI-U1

The Bosch Rexroth Indramat KDA 3.1-150-3-DQI-U1 from the KDA Spindle Drives series by Bosch Rexroth Indramat integrates robust spindle control with a Rated Current of 150 A and a DC Bus Voltage of 300 V to deliver continuous power across an extensive speed range. This KDA Main Spindle Drive is engineered for high stiffness and precise positioning, making it ideal for demanding machining and milling applications. Designed as Design 1 with a compact footprint, it offers adaptability for integration into modern CNC architectures. The drive’s core Product KDA lineage underscores its heritage of reliability and performance in industrial settings.

Reliability is further enhanced by the Cooling: Forced Cooled by Heatsink Blower system, which maintains optimal operating temperatures under peak loads. The heatsink blower operates from an AC Supply Source for Heatsink Blower of 115 VAC, ensuring consistent thermal management in harsh environments. Precision feedback is guaranteed via an Aux. Interface: Incremental Encoder Output, while the Aux. Encoder Input accommodates a 1 V sinusoidal encoder signal for high-resolution speed feedback. Command inputs are handled through the Speed Command Value: Digital 16-Bit Parallel interface, ensuring rapid and accurate capture of setpoints.

Compact and powerful, the KDA 3.1-150-3-DQI-U1 spindle drive simplifies commissioning and maintenance with its standardized design elements and clear sensor interfaces. Its combination of high current capacity, forced cooling, and digital control channels makes it a solid choice for high-speed spindles in woodworking, metalworking, and composite machining centers. Backed by Bosch Rexroth Indramat’s quality assurance, this drive offers long-term uptime and productivity for complex manufacturing processes.
