KDA 3.1-100-3-A0I-W1

KDA 3.1-100-3-A0I-W1, manufactured by Bosch Rexroth Indramat, is part of the robust KDA Spindle Drives series designed for demanding main spindle applications. This drive delivers a Rated Current of 100 A and operates on a DC Bus Voltage of 300 V, ensuring stable power for high-stiffness machining tasks. Its compact form factor houses a precision-engineered power stage with integrated safety margins for peak loads. With a responsive control loop and analog reference input, it excels in applications requiring rapid acceleration and deceleration.

Built for seamless integration, the KDA 3.1-100-3-A0I-W1 supports a Speed Command Value of Analog +/- 10V and includes an Aux. Interface featuring an Incremental Encoder Output for closed-loop position feedback. Cooling is managed by a Forced Cooled by Heatsink Blower system powered by an AC Supply Source for Heatsink Blower of 220 VAC, guaranteeing consistent thermal performance under continuous operation. Despite its advanced functions, the unit omits an Aux. Encoder Input, simplifying installation when secondary encoder channels are unnecessary. The drive’s modular Design (type 1) and series designation (3) facilitate straightforward configuration and maintenance, while standardized connections reduce installation time.

Engineers benefit from the drive’s high reliability and predictable performance in demanding CNC spindles and milling centers. Its forced-cooling arrangement and precise analog speed command interface minimize downtime by maintaining optimum operating temperatures. The KDA 3.1-100-3-A0I-W1 integrates easily within Bosch Rexroth automation environments, offering a proven solution for high-speed, high-precision applications.
