Product Description:

The DKS01.1-W050A-DS01-02 is a digital servo drive produced by Bosch Rexroth Indramat within the DKS Intelligent Digital Servo Drives series. It serves as the power and control interface between an automation controller and a synchronous servo motor. By regulating current and voltage, it carries out position, velocity, and torque commands accurately in industrial machinery. This arrangement helps the drive respond to changing load conditions and maintain stable motion on transfer, indexing, and positioning axes. Closed-loop positioning relies on DSF digital feedback, while two analog monitor channels provide ±10 V voltage or 4 mA current signals for external diagnostics.

This unit supplies a rated motor phase current of 50 A from a DC link stabilized at 300 V. The intermediate circuit is charged from a three-phase 3 x 230 V AC mains connection, and pulse-width modulation switches at 4 kHz for fine current resolution. Dynamic braking energy is routed to an internal bleeder that can absorb up to 9.4 kW in short bursts, which helps prevent DC-bus overvoltage during rapid deceleration. Heat generated by semiconductor switching is removed through passive cooling, and the drive has an IP10 protection class for open-frame installation inside a protected control cabinet. The stabilized bus supports consistent power conversion during acceleration and deceleration cycles.

Continuous regeneration is limited to 0.35 kW, so application duty cycles must stay within that thermal envelope. Total internal losses reach 305 W at maximum load, and the housing weighs 11 kg, allowing direct panel mounting without additional support brackets. Because the unit dissipates several hundred watts at high load, enclosure ventilation must carry heat away from nearby components. Operation is permitted at ambient temperatures up to 55 °C and elevations up to 1000 m, with derating required above those limits. Noise emission is standard, and version 1 firmware governs the drive logic and communication routines.
