Product Description:
The KDA 2.1-150-3-D00-U1 is a Spindle Drive manufactured by Bosch Rexroth and is designed for reliable operation in demanding CNC and industrial automation applications. It belongs to the KDA series for precise spindle control and construction. This drive uses a DC bus voltage of 300 volts and provides a rated current of 150 amperes to deliver strong and stable spindle performance.
The KDA 2.1-150-3-D00-U1 spindle drive includes a cooling system ensured by a forced air system with a heatsink blower. The blower itself is powered through a 220 VAC supply for uninterrupted thermal management. The drive communicates through a SERCOS interface for fast and precise speed command inputs from the control system. It includes an auxiliary feedback interface that supports incremental encoder outputs. There is also an auxiliary encoder input, available in a “Without” option for applications requiring customized feedback or alternative sensor systems. The KDA 2.1-150-3-D00-U1 spindle drive offers reliable electrical protection with short circuit monitoring and overcurrent detection. It also includes system safeguards like ground fault protection and thermal sensors for internal safety. The rugged housing, integrated diagnostics, and modular construction make maintenance simple while ensuring long service life under continuous use.
The encoder interface of KDA 2.1-150-3-D00-U1 spindle drive supports standard incremental encoders with high resolution, typically 1024 or 2048 pulses per revolution for accurate motion feedback and machining tasks. The unit is rated for humidity up to 95% non-condensing, allowing reliable function in machine shop conditions. It can operate at elevations up to 1000 meters without performance loss. The design resists vibration levels up to 1g for heavy industrial setups with stable mounting. The drive is widely used in milling machines, turning centers, and precision grinding systems, where dependable spindle control is critical.
