Product Description:
The Bosch Rexroth Indramat DKS01.1-W050A-DA01-00 is a digital servo drive in the DKS Intelligent Digital Servo Drives series. Designed for closed-loop positioning and velocity control, the unit interfaces between a motion controller and an AC servo motor, converting command signals into regulated three-phase output. In automated assembly lines, packaging stations, and material-handling axes, it provides the regulated power and feedback processing needed to maintain precise motion profiles under changing mechanical loads. This arrangement allows the drive to support repeatable axis behavior during acceleration, steady running, and commanded stopping without adding unnecessary complexity to the control structure.
Its output stage can deliver a continuous phase current of 25 A, while momentary load surges are handled with a peak capability of 50 A. These currents are supplied from an internal DC link stabilized at 300 V and fed by a mains supply of 3 × 230 V AC at 50–60 Hz. Pulse-width modulation at 4 kHz shapes the inverter waveform so the connected motor runs smoothly with reduced torque ripple. The DSF encoder interface closes the control loop by returning high-resolution position data to the drive, and electronic monitoring keeps current draw within the stated operating limits. This control method supports stable speed regulation and accurate response when the axis is following changing command values.
When decelerating a large inertial load, the integrated bleeder transistor channels excess energy into an external resistor that can absorb up to 9.4 kW of instantaneous power, helping prevent DC-link overvoltage. During rated operation, the converter itself dissipates 305 W of heat, which the housing releases by natural convection. An IP10 construction limits accidental contact with live parts while still allowing airflow, so the drive must be installed inside a cabinet. Operation is intended for ambient temperatures from +5 °C to +45 °C at altitudes up to 1000 m. Storage from −30 °C to +85 °C helps protect internal components during transport and spare parts storage.
