KDA 3.2-050-3-D00-W1

The KDA 3.2-050-3-D00-W1, Bosch Rexroth Indramat, KDA Spindle Drives controller is engineered for precise digital control of synchronous and frameless spindle motors. This versatile unit integrates advanced microprocessor-based drive control with onboard diagnostics to ensure consistent performance under demanding conditions. It supports both speed control and position control applications with a broad output power range from 3 to 22 kW. Professional-grade design and robust monitoring functions make this drive suitable for industrial automation and precision machining tasks.

The drive delivers a Rated Voltage of 300 V to the DC bus and sustains a Current Rated output of 50 A with a Continuous Current of 35 A, enabling reliable torque delivery. The integrated blower requires a Rated Connection Voltage for attached Blower of AC 50–60 V, while the control electronics draw 1.2 A at +24 V and 0.16 A at ±15 V for measurement and regulation functions. Speed references are accepted via a Speed Command Value: Digital 16-Bit Parallel interface, and the device intentionally omits an encoder input (Aux. Encoder Input: Without Aux. Interface1) to simplify configuration in pure speed-regulation roles. Key identifiers such as Product: KDA, Series: 3, and Design: 2 denote its place in the Rexroth Indramat lineup, ensuring compatibility with modular drive families.

Engineered for seamless integration into existing automation architectures, the KDA 3.2-050-3-D00-W1 drive controller delivers high reliability through rugged IP10 construction and temperature-hardened components. Its forced-air cooling via an onboard blower maintains stable operation across the specified 5 °C to 45 °C ambient range, with graceful derating up to 55 °C. Ideal for CNC spindles, high-precision milling machines, and robotics, this controller streamlines commissioning and minimizes downtime by leveraging standardized interfaces and proven Rexroth Indramat control algorithms.
