Product Description:
The KDA 1.1-150-300-W1-220 is a spindle-drive controller module produced by Bosch Rexroth Indramat and supplied within the KDA Spindle Drives series. Acting between a shared DC bus and a motorized spindle, it converts constant-voltage power into regulated three-phase output so machining centers can hold programmed speeds under changing tool loads. By following an external analog reference, it works with numerical controls to deliver smooth acceleration and stable cutting speed during drilling, milling, and similar metal-cutting processes. That control behavior is important in machine tools where spindle speed must stay steady as cutting resistance rises and falls through a machining cycle. The 1.1 suffix indicates series 1 and version 1 for this model.
At the power stage, the module accepts a regulated bus of 300 VDC and can deliver up to 150 A of continuous output current to the spindle motor. Speed is commanded through a ±10 V analog signal, letting the controller follow velocity setpoints generated by the CNC without a digital network. This analog command path is useful in systems that already use voltage-based spindle references. Thermal energy is removed by forced-air cooling, and the internal blower operates from a 220 VAC supply at 50/60 Hz. This cooling arrangement supports stable operation during prolonged high-current cycles. The specified ambient operating window of 5 to 45 °C allows the unit to run across normal shop-floor temperatures without added cooling hardware.
For cabinet integration, the housing measures 51 × 40 × 31 cm and weighs 15.40 kg, so it fits medium-sized control enclosures without excessive mounting load. Its size and mass are practical for standard industrial backplate installations and still leave space for adjacent power components and cable routing. Reliable operation is permitted up to 1000 m above sea level, where cooling performance remains suitable for rated output. The controller has no auxiliary encoder input and no auxiliary interface, so wiring is limited to the primary feedback connector and power terminals. This layout keeps the connection scheme straightforward and leaves the main control and power paths easy to trace.
