Product Description:

Bosch Rexroth Indramat builds the DKS01.1-W100A-R as part of the DKS Intelligent Digital Servo Drives series. The unit is a digital servo drive intended to run MDD synchronous servomotors in automated machinery, converting three-phase mains power into controlled DC bus power and pulse-width-modulated motor output for precise velocity and torque control. Its resolver interface gives the control system the feedback needed for closed-loop operation, while the compact drive package supports axis modules used in packaging lines, material-handling gantries, and similar industrial equipment. That role makes it suitable for coordinated servo axes where the drive must respond quickly to command changes without losing speed stability.

The drive accepts a three-phase supply of 3 × 230 V AC, which is rectified to a regulated DC link held at 300 V. A built-in braking resistor dissipates regenerated energy, with a continuous capability of 0.5 kW and short bursts up to 18 kW during rapid deceleration, which helps prevent overvoltage in the bus capacitors. This arrangement lets the unit absorb braking energy locally instead of allowing it to accumulate on the DC bus during frequent stop-and-go motion. For motor output, the inverter section is rated to deliver 100 A RMS, matching the current demand of high-torque MDD motors during acceleration and load changes. Heat from these conversion stages is removed through passive dissipation across the aluminum housing, so no forced airflow is required and cabinet layout remains straightforward.

The inverter modulates phase voltage at a carrier of 4 kHz, a switching speed that balances acoustic behavior with current ripple. Under worst-case loading, the housing releases up to 480 W as thermal loss, so the surrounding enclosure must allow that heat to dissipate without trapping it near adjacent components. The enclosure is classified as IP10, so the drive is intended for installation inside a protected control cabinet, and operation is permitted at altitudes up to 1000 m. Physical dimensions are 390 mm high, 260 mm deep, and 170 mm wide, and the internal electronics follow version 1 noise-emission requirements while using resolver feedback for position control. Its dimensions fit cabinet-mounted drive assemblies where vertical stacking and service access must be considered during panel layout.
