Product Description:

The DKS01.1-W030B-RL02-01-FW intelligent digital servo drive is produced by Bosch Rexroth Indramat for the DKS Intelligent Digital Servo Drives series. It conditions incoming mains power, supplies a regulated DC bus, and delivers pulse-width modulated phases to a connected MDD motor so torque and speed follow the control loop accurately. Resolver feedback from the motor rotor supports the drive’s internal position calculations, giving stable commutation and closed-loop correction during load changes. Because the control stage continuously compares commanded and actual rotor position, it can correct speed deviations before they become noticeable positioning errors. This operating profile suits pick-and-place stations, indexing tables, and other automation axes that require repeatable motion with quick response.

The power section accepts 230 VAC and converts it to a stabilized bus of 300 V, which supports rapid energy exchange between the inverter and the motor during acceleration and regeneration. Continuous phase current is limited to 30 A, which sets the thermal load for the power semiconductors and connected cabling during ongoing operation. Switching is executed at 18 kHz, a carrier frequency that reduces audible noise and improves current waveform quality at the motor terminals. This switching behavior also helps the motor run more smoothly through typical servo speed ranges. Surplus kinetic energy is dissipated through an internal bleeder that handles 0.3 kW continuously, and the unit uses natural heat dissipation rather than forced airflow.

A separate resistor path supports peak absorption of 5 kW during brief deceleration events, helping prevent DC bus overvoltage when high-inertia axes stop abruptly. The drive can be installed up to 1000 m above sea level without derating, and the housing has an IP 10 rating intended for clean electrical rooms and protected cabinet spaces. The unit has a width of 170 mm, a height of 390 mm, and a depth of 260 mm, so multiple axes can be mounted side by side in standard racks where panel space is limited. Its narrow housing helps conserve rack space in multi-axis cabinets. The product is Version 1, and resolver processing is built into the drive for stable motor control with low operating noise.
