KDA 2.1-150-3-D0S-W1

The Bosch Rexroth Indramat KDA 2.1-150-3-D0S-W1 spindle drive is a powerful addition to the KDA Spindle Drives series manufactured by Bosch Rexroth Indramat. It features a Rated Current of 150 A and a DC Bus Voltage of 300 V, making it well suited for high-stiffness applications requiring precise speed control. This drive utilizes a Digital 16-Bit Parallel Speed Command Value for accurate spindle positioning and speed regulation. Designed specifically as a main spindle drive, it delivers continuous power across a broad operational range and supports demanding machining and heavy-duty processing tasks.

In terms of technical specifications, the KDA 2.1-150-3-D0S-W1 offers reliable cooling via a Forced Cooled by Heatsink Blower system operating on a 220 VAC AC supply source. The design (Type 1) integrates an efficient heat sink blower to maintain optimal thermal conditions during sustained operation. Connectivity is provided through a Serial Interface RS 232 C auxiliary interface, while it omits an auxiliary encoder input. The drive's internal DC link is rated at 300 V, ensuring stable power delivery and minimal voltage fluctuations under load. The product series indicator (Series 2) and model designation (Product KDA) reflect its lineage in the proven KDA platform of spindle controllers.

Additional features include compliance with standard industrial voltage levels and compatibility with common machine tool architectures. Its forced cooling mechanism enhances durability by preventing overheating and reducing maintenance intervals. The absence of an auxiliary encoder input simplifies integration into applications where encoder feedback is managed externally. The drive's digital speed command interface ensures high-resolution speed regulation and rapid response to control signals. Overall, the KDA 2.1-150-3-D0S-W1 delivers robustness and precision, enabling manufacturers to improve machining accuracy, reduce cycle times, and boost production efficiency in demanding industrial environments.
