KDA 3.2-150-3-D0I-W1

KDA 3.2-150-3-D0I-W1, Bosch Rexroth Indramat, KDA Spindle Drives opens a new benchmark in drive control for high-stiffness spindle applications. The KDA 3.2-150-3-D0I-W1 Drive Controller by Bosch Rexroth Indramat in the KDA Spindle Drives series delivers precise motion through its integrated control architecture. It features a Current Rated of 150 A and a Continuous Current capability of 90 A, ensuring robust torque delivery across a wide operating envelope. The controller accepts a Rated Voltage of 300 V and interfaces with a forced-cooling Heatsink Blower powered at AC 50–60 Hz.

Designed for demanding spindle duties, the unit employs a Digital 16-Bit Parallel Speed Command Value channel for sub-microsecond response to reference inputs. The modular design (Product: KDA, Series: 3, Design: 2) supports seamless integration in multi-axis systems. With an Aux. Encoder Input configuration of Without Aux. Interface1, the controller interfaces directly to single-turn and multi-turn encoders, preserving signal integrity. The forced-cooled heatsink blower maintains thermal stability under high-loading cycles. The compact housing and internal bus links facilitate cabinet mounting with minimal footprint.

Engineered for reliability, this spindle drive controller simplifies commissioning by leveraging Bosch Rexroth’s diagnostic toolset and standardized I/O topology. High-speed processing and precise overcurrent protection routines safeguard both machine and motor, while the robust control loops enable stable positioning under rapid acceleration. Integrators will appreciate the straightforward interface and the drive’s proven performance in machining centers, grinding machines, and high-precision lathes where stiffness and speed consistency are critical.
