Product Description:
The KDF2.2-050-300-W0-220 is a drive from Bosch Rexroth Indramat in the KDF Variable Frequency Drives series. In automated handling cells or machining centers, it acts as the power interface between the plant's DC link and an AC motor, delivering variable output frequency so axes accelerate, decelerate, and hold speed on command. When the unit is installed in a cabinet next to a motion controller, it provides scalable torque and speed control without additional mechanical gear changes, helping conveyor belts, pumps, and spindle packages follow programmed cycles accurately.
This model draws and regulates up to 50 A of output current, giving enough margin to start induction machines under load. Its internal bus is energized at 300 VDC, a level suited for multi-axis installations. Auxiliary electronics and the cooling fan share a separate 220 VAC supply so that logic power remains stable even if the main link fluctuates. When paired with a matched motor, the inverter can deliver up to 25 hp, allowing one frame size to cover conveyor drives, hydraulic pump replacements, or tool spindles. Electronic commutation supports commanded speeds as high as 8000 rpm, which suits high-speed processes such as drilling or winding while keeping motor operation within its intended range.
The microcontroller in the KDF platform exchanges velocity references and diagnostic data across a 16-bit command word, which provides fine resolution for incremental adjustments in coordinated motion tasks. Thermal management is handled by convection cooling, eliminating forced-air ducts and reducing service needs in dusty environments. A dedicated encoder channel enables closed-loop position control, and the velocity loop is managed by a digital microprocessor-based control system that adjusts proportional and integral gains in real time to reject load disturbances without oscillation.
