Product Description:
The KDA 2.1-150-3-AQD-U1 Spindle Drive from Bosch Rexroth Indramat is a drive component for automation tasks in industrial environments. The unit is built for consistent operation during extended duty. Stable functionality supports efficiency in motion control systems where precision and reliability are essential.
The KDA 2.1-150-3-AQD-U1 Spindle Drive is defined by high stiffness. Such structural rigidity reduces torsional deformation and ensures repeatable positioning accuracy during load changes. The rated current is 150 A. This level provides the electrical capacity necessary for sustained torque delivery in continuous duty cycles. The voltage type is DC Bus. Using a direct current bus allows stable supply conditions and improved conversion efficiency in automated systems. The nominal operating voltage equals 300 V. Operating at this voltage ensures compatibility with standardized power networks and stable performance under industrial conditions. The speed command is processed in analog form. Continuous analog reference input permits smooth acceleration and fine regulation of spindle speed. The specified command value is ±10 V which provides a clear control range for accurate velocity adjustment. Such parameters contribute to precise response during production sequences.
The KDA 2.1-150-3-AQD-U1 Spindle Drive integrates an auxiliary interface. The presence of this channel facilitates system interconnection and external monitoring functions. The auxiliary interface transmits data through a digital signal type which reduces susceptibility to noise and ensures reliable exchange of control information. The interface supports 16-bit parallel resolution. This level of resolution improves feedback granularity and enables precise coordination with higher-level controllers. The command type is designated as a position command value. This allows the drive to track reference positions directly, ensuring accurate axis alignment in automation processes. The overall configuration of KDA 2.1-150-3-AQD-U1 Spindle Drive supports stable integration in industrial systems requiring controlled spindle operation.
