Product Description:

The DKS01.1-W050A-RL01-00 is a digital servo drive produced by Bosch Rexroth Indramat within the DKS Intelligent Digital Servo Drives series. Acting as a closed-loop power stage, it conditions three-phase supply energy and delivers precisely regulated current to a matched servo motor so that commanded position and velocity profiles are followed in automated machinery without relying on external current control hardware. The unit is intended for cabinet installation, where it supports motion axes on packaging lines, material-handling gantries, and general assembly cells by combining power conversion, regenerative braking handling, and diagnostic signaling in one module.

The drive accepts a three-phase input of 230 VAC and can supply up to 50 A of continuous motor current. Inside the converter, energy is buffered on a 300 VDC bus that supports quick acceleration and controlled deceleration during repeated starts, stops, and speed changes. Pulse-width modulation operates at 4 kHz, providing adequate current resolution while limiting switching losses and audible noise. The IP10 enclosure keeps fingers and large objects away from live conductors, but the drive still requires placement in a clean, dry, and ventilated control cabinet for operation within its thermal limits.

The drive includes an integrated bleeder circuit for regenerative energy produced during deceleration. Its bleeder resistor removes regenerative power at 0.35 kW continuously and can absorb peaks of 9.4 kW during abrupt stops, which helps the unit manage braking energy from dynamic axis motion. Under maximum load, the line side may draw 9.5 kVA, and conversion losses appear as only 305 W of heat, which helps simplify panel cooling calculations. Rated performance is maintained from 5 °C to 45 °C ambient and up to 1,000 m elevation with no derating, while operation beyond these limits requires load reduction or enhanced cooling. With a mass of 11 kg, the unit adds moderate weight to the cabinet while remaining suitable for continuous duty cycles.
