KDA 3.3-150-3-AYI-W1

The Bosch Rexroth Indramat KDA 3.3-150-3-AYI-W1 from the KDA Spindle Drives series delivers precision spindle control with a current rated of 150 A and a continuous output capacity of 90 A. Designed to operate on a 300 V DC bus and featuring a rated connection voltage for attached blower of AC 50–60, this controller maintains steady performance under heavy loads. Its robust power stage integrates seamlessly with industrial motors, delivering reliable torque and speed regulation. Modular in construction, the unit’s compact footprint simplifies cabinet integration and service access.

Engineered for advanced motion applications, the controller accepts a speed command value of Analog +/- 10V and offers versatile feedback options via an Aux. Encoder Input with auxiliary and synchronous inputs. The internal Design 3 architecture ensures consistent thermal management and fault tolerance. Built on the proven Product KDA platform, the drive supports high-bandwidth control loops and rapid response times. Safety and diagnostics are enhanced through built-in interface channels and status monitoring.

Ideal for CNC machining, robotics, and printing operations, this drive excels in tight-tolerance environments. Its seamless blower interface and industrial-grade electronics reduce setup time and maintenance intervals. The KDA 3.3-150-3-AYI-W1 combines flexible I/O, precise analog command, and proven hardware design for a turnkey spindle-drive solution in demanding automation systems.
