KDA 2.1-150-3-DQI-W1

KDA 2.1-150-3-DQI-W1, Bosch Rexroth Indramat, KDA Spindle Drives deliver precision spindle control in a robust, compact package optimized for demanding machining applications. This main spindle drive features high structural **stiffness** and integrated **positioning functions**, enabling rapid, accurate tool changes and minimal vibration under heavy loads. An extensive speed range supports continuous power delivery across low to high RPM regimes without compromising torque stability or thermal performance. Engineered for industrial CNC spindles, the unit’s modular design simplifies integration into existing drive systems.

Designed around a forced-air heat sink blower, this drive maintains safe operating temperatures via a **220 VAC AC supply source for heatsink blower** and an active **forced cooling** architecture. The onboard power stage handles a **DC Bus Voltage** of **300 V** while supplying a **rated current** of **150 A** for high-torque start-stop cycles. A **Digital 16-Bit Parallel Speed Command Value** interface ensures sub-microsecond response to motion commands, and dual encoder paths—**auxiliary encoder input with 1 V sinusoidal** support plus an **incremental encoder output** auxiliary interface—provide closed-loop feedback redundancy. Internally designated as **Design 1**, **Product KDA**, **Series 2**, the drive’s electronics are conformally coated and vibration-hardened for long service life.

Integration into machine tool PLCs and motion controllers is seamless, with standardized control signals and encoder interfaces reducing commissioning time. The KDA 2.1-150-3-DQI-W1’s rugged construction and precision cooling ensure reliable uptime in harsh shop-floor environments. Ideal for high-precision milling, drilling, and grinding spindles, this drive maximizes throughput while maintaining tight positional accuracy and dynamic performance. Please respond in JSON format.
