Product Description:
The KDA 3.1-150-3-DPS-U1 belongs to the KDA Spindle Drives series produced by Bosch Rexroth Indramat. Designed for machine-tool automation, this high-speed industrial spindle drive receives a stabilized DC link and governs synchronous or induction spindles through vector control. By adjusting torque and speed in real time, it helps machining centers, grinders, and lathes maintain surface finish and dimensional accuracy during cutting, drilling, or finishing tasks. Its control behavior is suited to applications that require stable spindle response during changing load conditions.
The power stage operates from a bus voltage of 300 VDC and can deliver a continuous armature current of 150 A, so the drive is suited to medium-to-large spindle motors that draw high torque during rapid starts and load changes. Thermal energy generated by the switching devices is removed by a heat sink-mounted blower, and the blower is powered from an auxiliary line of 115 V/50-60 Hz, allowing the use of standard single-phase utility power. A 16-bit parallel digital speed command channel provides the spindle velocity reference, giving fine command resolution for tasks such as threading or contour milling. A second encoder input accepts incremental or absolute feedback from the work spindle, which supports position-synchronized processes such as rigid tapping.
This drive is specified for ambient temperatures of 5 to 45 °C and installation heights up to 1000 m above sea level, so it is suitable for most factory environments when installed within those limits. Data exchange with supervisory controls is available through a serial interface (RS-232C), which supports parameter loading and diagnostic retrieval. Because the housing relies on forced cooling, airflow must remain unobstructed to keep internal components within their intended operating temperature range. Clear airflow around the unit also helps maintain consistent spindle performance during extended operation.
