Product Description:
Bosch Rexroth Indramat manufactures the KDF 1.2-150-300-W1-115 drive as part of the KDF Variable Frequency Drives series. The unit functions as a motor inverter that converts fixed mains power into a variable output for speed and torque regulation in industrial automation. By adjusting the electrical frequency delivered to a connected AC motor, it supports applications such as material handling, winding systems, and test stands where precise velocity control and bidirectional energy flow are required. This configuration allows the drive to manage acceleration, steady running, and controlled deceleration from a single power stage.
During operation, the drive supplies a rated output of 150 A, allowing it to energize machines that draw high continuous current without derating. Its internal DC link is stabilized at 300 VDC, giving the power stage a fixed voltage reference for pulse-width modulation. With a maximum motor shaft capacity of 25 hp, the module is matched to medium-frame induction or synchronous motors commonly found in conveyors and extruders. Cooling is provided by an external fan unit, so mounting inside sealed cabinets remains feasible when ambient airflow is limited. The control system supports operation from 0 to 8000 rpm, which accommodates both low-speed torque demand and high-speed production cycles. Its power section is suited to applications that require sustained load handling rather than brief peak duty alone.
Command references enter the controller as differential analog signals, minimizing noise pickup on long field cables, while time-critical setpoints can also be delivered through a parallel bus with 16-bit digital resolution for direct integration with PLCs. Energy handling is enabled by the four-quadrant power stage, permitting motoring and regenerative braking in both rotational directions. Speed feedback is processed by a microprocessor-based digital velocity loop, which improves dynamic accuracy during acceleration and deceleration. An internal routine provides positioning capability, allowing the drive to bring the motor to a stored position for indexing or tension control. That function supports repeatable moves without requiring a separate positioning module.
