KDA 3.1-100-3-AP0-W1

The Bosch Rexroth Indramat KDA 3.1-100-3-AP0-W1 spindle drive from the KDA Spindle Drives series is engineered for precision spindle control in demanding industrial environments. Supplied as a main spindle drive, it delivers a Rated Current of 100 A and operates on a robust DC Bus Voltage of 300 V to maintain continuous power delivery over a wide speed range. This drive's primary function is to provide high stiffness and accurate positioning for spindles, ensuring consistent throughput and repeatable machining performance. Its design supports complex motion profiles and sustained torque for machining, grinding, or drilling operations.

At the heart of the KDA 3.1-100-3-AP0-W1 are its advanced technical specifications. The drive's AC Supply Source for Heatsink Blower is 220 VAC, and its cooling system is Forced Cooled by Heatsink Blower, effectively dissipating heat generated at high current levels. Feedback integration is supported via an Aux. Encoder Input with capacity for spindle or secondary motor feedback, facilitating closed-loop control and high-resolution position feedback. The unit includes no auxiliary interface (Aux. Interface: Without), simplifying signal routing to essential encoding and power connections. Speed regulation is performed via an Analog +/- 10V Speed Command Value input, offering a familiar control method for drive speed modulation in CNC and PLC applications.

This spindle drive's compatibility with standard 220 VAC auxiliary supplies and a widely adopted speed command format enhances its integration into existing machine tool architectures. The robust 300 V DC bus and 100 A rating guarantee that the drive can withstand variable load conditions without voltage sag or current limit interruptions. Forced cooling by means of a dedicated heatsink blower ensures efficient thermal management in high-duty cycles, reducing the risk of overheating and prolonging component life. Although no formal certifications are listed, the use of proven Bosch Rexroth Indramat components aligns with industry reliability expectations. Deploying the KDA 3.1-100-3-AP0-W1 in industrial applications yields improved spindle responsiveness, precise speed control, and greater uptime for high-volume production environments.
