KDA 3.3-150-3-D00-W1

The KDA 3.3-150-3-D00-W1, Bosch Rexroth Indramat, KDA Spindle Drives controller features a modular structure designed for the digital control of frameless spindle and asynchronous motors. It integrates seamlessly into multi-axis drive architectures via parameterization and supports configurable operation modes to match diverse application demands. The unit deploys a forced cooling system to maintain optimal thermal performance during extended runtime. Its compact footprint and vertical mounting orientation simplify installation inside closed cabinets, while top-positioned grounding bolts enhance safety and service accessibility.

The controller delivers a Current Rated: 150 A peak output and maintains a Continuous Current: 90 A for sustained spindle acceleration and load handling. It operates on a Rated Voltage: 300 V DC bus and powers its blower through a Rated Connection Voltage for attached Blower: AC 50-60 supply, ensuring reliable forced-air cooling. Command signals are processed via a Speed Command Value: Digital 16-Bit Parallel interface, and the drive omits auxiliary inputs (Aux. Encoder Input: WithoutAux. Interface1) for streamlined wiring. Built-in identifiers—Product: KDA, Series: 3, Design: 3—simplify part tracking and system documentation.

Engineers appreciate the drive’s direct ground connection to the supply module, which enhances electromagnetic compatibility and operational safety. The robust enclosure and precise vertical alignment requirements guarantee mechanical stability under industrial vibration. Backed by a one-year warranty and designed for global dispatch, the KDA 3.3-150-3-D00-W1 delivers reliable performance in demanding CNC and automated spindle applications.
