KDA 2.1-100-3-A0S-W1

The Bosch Rexroth Indramat KDA 2.1-100-3-A0S-W1 from the KDA Spindle Drives series is a precision drive controller designed for high-demand automation tasks. It incorporates a Rated Voltage 300 V DC bus providing stable energy to the spindle and supports a Current Rated 100 A peak with a Continous Current 70 A capacity for sustained performance. The drive’s integrated power stage (Product KDA, Design 1, Series 2) enables rapid torque response while maintaining tight speed control. Critical to its versatility, the device accepts a Speed Command Value Analog +/-10V input and features an Aux. Encoder Input Without Aux. Interface1 for encoder-feedback applications.

The controller’s cooling system interfaces with an attached blower via a Rated Connection Voltage for attached Blower AC 50–60 Hz, ensuring optimal thermal management under full-load conditions and reducing thermal cycling effects. Precision drive performance is sustained by the built-in power electronics configured for Design 1 with a Series 2 topology tailored for high-speed spindle motors, enabling rapid current loop response. Tight voltage regulation and advanced current control algorithms minimize torque ripple, maintain stable speed profiles, and deliver superior positioning accuracy during complex machining routines. Its rugged construction and reinforced PCB layout offer enhanced immunity against voltage transients, electromagnetic interference, and vibration, maximizing uptime in harsh industrial settings.

This drive controller streamlines commissioning and maintenance through standard signal interfaces, intuitive parameter settings, and clear diagnostic feedback channels. Engineered for 24/7 continuous operation, the KDA 2.1-100-3-A0S-W1 ensures consistent output over extended production cycles, making it ideal for precision CNC machining, milling centers, and high-speed tool applications. Its compatibility with common PLC systems and modular cabling conventions simplifies automation workflows and minimizes engineering overhead.
