KDA 3.3-150-3-AP0-U1

The Bosch Rexroth Indramat KDA 3.3-150-3-AP0-U1 from the KDA Spindle Drives series delivers robust spindle control with a current rated of 150 A and a continuous current of 90 A to meet demanding machining workloads. This drive operates at a rated voltage of 300 V and supports a rated connection voltage for attached blower of AC 50–60 Hz to maintain efficient thermal management. The controller is classified under Product KDA, Series 3, and Design 3, ensuring consistency across Bosch Rexroth’s modular offerings. Engineers will appreciate the compact footprint and straightforward integration with existing automation lines.

Installation and configuration are streamlined through an analog +/- 10V speed command value interface and a dedicated Aux. Encoder Input: With for Spindle or Second Motor Feedback channel for high-precision feedback loops. The drive’s single Aux. Interface1 port provides a clear path for auxiliary signals without complex cabling schemes. With its forced cooling via an attached blower circuit, monitored by the specified blower connection voltage, the drive maintains optimal junction temperatures for reliable long-term operation. Commissioning is simplified by built-in parameter memory, allowing rapid cloning of settings across multiple units.

Maintenance protocols demand that the parameter board be transferred when replacing units to preserve critical motor and control data. Adhering to the specified current rated and continuous current values ensures the drive operates within its thermal and electrical limits, safeguarding spindle axes and tooling. The KDA 3.3-150-3-AP0-U1 represents a precision drive solution tailored for modern CNC and high-speed spindles where reliability and accuracy are paramount.
