KDA 2.1-100-3-AQS-W1

The Bosch Rexroth Indramat KDA 2.1-100-3-AQS-W1 from the KDA Spindle Drives series by Bosch Rexroth Indramat delivers precision spindle control with a Rated Current of 100 A and a DC Bus Voltage of 300 V. Designed as part of the robust Product KDA, Design 1 lineup, it offers a wide, continuous power range and high rigidity for demanding machining applications. The drive accepts an Analog +/- 10V Speed Command Value to facilitate smooth acceleration profiles and precise speed regulation. With a compact, modular housing suited to high-density cabinet integration, the unit streamlines modern CNC installations.

Engineered for superior operational flexibility, the drive features a dedicated AC Supply Source for Heatsink Blower of 220 VAC and is Forced Cooled by Heatsink Blower to maintain optimal thermal conditions under sustained loads. An integrated Aux. Encoder Input for 1V Sinusoidal Enc. ensures accurate position feedback, while a Serial Interface RS 232 C Aux. Interface supports straightforward parameterization and diagnostic exchanges. The sealed enclosure and forced-cooling architecture combine to protect electronics from particulate ingress and thermal stress during high-speed duty cycles. Field service is further simplified by standardized connector layouts and accessible fan units for rapid maintenance turnover.

Ideal for spindle drive tasks requiring enhanced stiffness and dynamic response, the KDA 2.1-100-3-AQS-W1 excels in milling, drilling, and finishing operations. Its combination of Series 2 hardware maturity, precise speed command, and reliable encoder integration makes it a go-to solution for machine builders prioritizing uptime and repeatable performance. With Bosch Rexroth Indramat’s legacy of industrial drive technology, this spindle drive represents a technically advanced yet proven component in any high-precision manufacturing system.
