KDA 3.3-150-3-D0D-W1

The Bosch Rexroth Indramat KDA 3.3-150-3-D0D-W1 from the KDA Spindle Drives delivers precision spindle control with a Current Rated of 150 A and a Continuous Current of 90 A. It is engineered for a Rated Voltage of 300 V input and supports a Rated Connection Voltage for attached Blower of AC 50 60 Hz. Control signals are processed via a Speed Command Value Digital 16-Bit Parallel interface, while feedback is handled through the Aux. Encoder Input WithoutAux. Interface1. This unit conforms to Series 3 and Design 3 specifications for seamless integration into high-performance machining centers.

Designed around a dedicated microcomputer, the drive features a front-mounted rating plate and a programming module for storing both parameters and operating software. All drive-specific parameters—including synchronization pulses between drive and motor—are entered via the integrated keypad on the user terminal. The controller draws DC-link voltage over two busbars and maintains ground integrity with a minimum 10 mmB2 grounding conductor cross-section. Installation is simplified by mounting the drive in close proximity to its supply module and by using a standard DC bus connection cable for control power.

Thermal management is handled through a rear-mounted heatsink and integrated heatsink blower rated at 220 V 50 60 Hz, ensuring heat dissipation occurs outside the control enclosure. The KDA 3.3-150-3-D0D-W1 drive offers high stiffness and positioning accuracy across a wide speed control range down to 0.0005 rpm. With a one-year warranty and robust construction, this drive controller is shipped safely via major carriers and is ready to elevate spindle performance in demanding industrial environments.
