KDA 3.3-150-3-A01-W1

The Bosch Rexroth Indramat KDA 3.3-150-3-A01-W1 from the KDA Spindle Drives series delivers precision motion control with a rated voltage of 300 V and a current rating of 150 A. Engineered for demanding industrial environments, this drive offers a continuous current of 90 A and accommodates a rated connection voltage for the attached blower of AC 50–60 Hz. Robust internal circuitry ensures stability under varying loads, while the compact form factor simplifies mounting within control cabinets. Seamless integration into existing systems is guaranteed thanks to its adherence to industry-standard electrical and mechanical interfaces.

The KDA 3.3-150-3-A01-W1 drive controller operates without the need for an auxiliary encoder input, relying instead on its built-in incremental encoder output for high-resolution feedback. Speed commands are accepted via an analog ±10 V speed command interface, enabling smooth acceleration and deceleration profiles. Thermal management is handled by a forced-cooling heat sink blower powered at 220 VAC, which maintains optimal operating temperatures even under prolonged duty cycles. EMI suppression and electrical isolation measures are incorporated to ensure reliable performance in high-noise power environments.

Optional communication and control interfaces expand the versatility of this spindle drive, including a digital parallel speed interface, a SERCOS interface for real-time deterministic networking, and a dedicated position command value interface for advanced motion synchronization. Each feature has been validated to maintain consistent performance across long-term operation, making the KDA 3.3-150-3-A01-W1 an ideal solution for high-precision spindle applications in machining centers, grinding machines, and dynamic turntables.
