KDA 2.1-150-3-AYS-W1

The KDA 2.1-150-3-AYS-W1 spindle drive by Bosch Rexroth Indramat is a member of the robust KDA Spindle Drives family designed for precision machining. Its compact form houses high-stiffness electronics and advanced positioning algorithms to deliver consistent torque under dynamic load. Capable of serving both milling and grinding spindles, it offers a broad speed range supported by continuous power delivery and precise speed control. Integrated fault detection and thermal monitoring safeguards enhance operational uptime in demanding industrial environments.

Incorporating a Product Model designation of KDA Series 2 Design 1, this drive accepts a DC Bus Voltage of 300 V and provides a Rated Current of 150 A for sustained spindle operation. Thermal management relies on a Cooling Method of Forced air via heatsink blower, driven by a dedicated AC Supply for Blower at 220 VAC. Feedback is handled through an Encoder Input capable of Auxiliary & synchronous (AS 35) signal processing, while speed setpoints are accepted as an Speed Command Input of Analog ±10 V. Communication and parameterization occur over an Auxiliary Interface using RS-232C serial, simplifying integration into legacy and modern CNC controls alike.

Engineers benefit from seamless integration with Rexroth PLCs and CNC systems, enabling synchronized multi-axis motion and automated tool change routines. The drive’s hardened construction and forced-air cooling underpin exceptional reliability, even under high duty cycles and elevated ambient temperatures. In machine tool applications, the KDA 2.1-150-3-AYS-W1 ensures precision spindle control, reduced vibration, and prolonged component life.
