Product Description:
Type code KDA 2.1-150-3-AP0-U1-115 is a best quality product from the Bosch Rexroth brand as part of the famous KDA Spindle Drives range. It is a power module that supplies the main power stage required for spindle actuation and control. It comprises of analog communication interface, providing standard speed command and status lines that match legacy control architectures and permit simple signal wiring.
Function module “U1” defines the internal functional configuration and ensures the module fits the KDA control topology for consistent integration. The device with resolver feedback option supplies absolute angular position information. This maintains the control loop to reference rotor position without additional homing sequences. Panel mount installation secures the spindle drive to a control panel which eases wiring access and fixes mechanical alignment. The protection class IP20 requires enclosure installation and protects internal electronics from contact with fingers and large objects. These compatible motors are listed as Indramat AC motors align electrical and control parameters to simplify drive and motor pairing.
Physical dimensions are described as standard for the KDA 2.1 series and provide a reference for cabinet layout and spacing during system design. KDA 2.1-150-3-AP0-U1-115 specifies a rated current of 150 A to determine conductor sizing and peak torque capability for connected spindles. The unit’s axis numbers are defined as “three”, indicating support for three independent control channels or coordinated spindle outputs in modular systems. “AP0” in the model number denotes “air-cooled” process for removing heat by forced airflow, thus avoids liquid circuits and simplifies maintenance. This control voltage of 115 V provides the internal reference supply for control electronics and associated auxiliaries.
