Product Description:

The KDA 3.2-050-3-LPI-U1 Spindle Drive is an efficient product from a renowned manufacturer Bosch Rexroth Indramat known for its innovative motion control solutions. It is available with a heavy duty design 2 and is part of the series 3 and represents an ideal combination of both advanced engineering and reliability.

The KDA 3.2-050-3-LPI-U1 drive stands out with its unparalleled positioning and speed control and offers a level of precision and responsiveness that is essential for demanding applications. It has an exceedingly large range of speeds that makes it suited to a wide variety of processes and flexible to different jobs and still being reliable over a range of different operating speeds. It is produced in multi axis operation and performs well in an environment where several motors or elements are required to operate. This module is well suited in environments which demand well-timed movements because it facilitates smooth combination and provision of synchronization in numerous axes. This module has forced cooling through a heatsink blower that efficiently controls the thermal loads through an optimization of overall performance even under extended work. It has a 115 volts AC source of supply to its heatsink blower to provide optimum cooling and performance. The blower alternating current supplies runs efficiently on 50 to 60 hertz frequencies which aids in reliability within varied overseas conditions despite fluctuation in strengths of regional power sources.

This KDA 3.2-050-3-LPI-U1 drive is powered by a direct current bus voltage of 300 volts to ensure efficient operation and consistent performance. It interfaces an incremental encoder output using its auxiliary interface to facilitate its robust capabilities that give accurate feedback to control and monitor. It can control both positioning and speed to an extent that can improve overall system performance.
