Product Description:

The Bosch Rexroth Indramat DKS01.1-W030B-RL01-01 belongs to the DKS Intelligent Digital Servo Drives series. This stand-alone drive links the plant power network to a servo motor and converts incoming line power into a pulse-width-modulated output for controlled motion. In normal machine operation, the automation controller sends motion commands while the drive regulates motor current so the axis follows the requested path with stable speed and torque behavior. It is suited for conveyors, pick-and-place axes, and other automated assemblies that repeat short, accurate motion cycles.

The drive operates from a three-phase supply of 230 V AC (±10%), which the rectifier section raises to an internal bus of 300 V DC for energy storage and distribution. A continuous output current of 30 A is available to the motor phases, and the switching stage operates at 18 kHz to reduce current ripple and audible noise. Surplus kinetic energy during deceleration is absorbed by an internal bleeder rated for 0.3 kW continuous dissipation, which helps keep the DC bus within its operating range during repeated slowdowns. Thermal removal relies on heat transfer through the mounting surface rather than an external fan. Resolver feedback provides analog position signals that remain reliable in electrically noisy industrial environments.

During rapid stops or emergency events, the bleeder can briefly handle 5 kW to limit DC-bus overvoltage. The unit can be installed up to 1000 m above sea level without derating, and it continues to operate with reduced current at ambient temperatures up to +55 °C. Overall power drawn from the mains is limited to 15 kVA, which helps size the incoming supply for the drive. The IP10 enclosure reflects an open design intended for installation inside a protective cabinet, where the electronics remain protected from accidental contact. The drive is version 1.
