KDA 2.1-150-3-LYS-W1

The Bosch Rexroth Indramat KDA 2.1-150-3-LYS-W1 from the KDA Spindle Drives series is engineered as a high-performance spindle drive with a rated current of 150 A and a DC Bus Voltage of 300 V. This drive accepts an AC Supply (Blower) of 220 VAC and communicates via a Speed Command Interface: SERCOS for deterministic real-time control. Service and diagnostics link through the Auxiliary Interface RS-232C serial port, ensuring clear parameter exchange. The unit is built on the proven Product Series: KDA Series 2 architecture and identified simply as Product: KDA with Design: 1.

Reliability is assured by the Cooling Method: Forced by heatsink blower, which maintains optimal thermal conditions under continuous loads. Precise motion feedback is enabled through the Encoder Input Type: Auxiliary & synchronous (AS35) channel, supporting advanced position and speed regulation. The compact enclosure houses rugged power electronics and a high-efficiency blower assembly, balancing airflow and acoustic performance. The drive’s modular design simplifies maintenance and replacement of the heatsink blower without extensive downtime.

Ideal for high-stiffness milling and turning applications, the KDA 2.1-150-3-LYS-W1 spindle drive delivers wide speed range and constant torque over extended duty cycles. Its comprehensive SERCOS interface and RS-232C auxiliary link accelerate commissioning, while robust thermal management enables peak productivity in industrial machine tools. The result is a dependable, flexible spindle drive solution for precision machining and dynamic positioning tasks.
