Product Description:

The DKS01.1-W030B-RA01-00 is an intelligent digital servo drive produced by Bosch Rexroth Indramat for the DKS Intelligent Digital Servo Drives series. It links to Indramat motion controllers to deliver regulated three-phase power to synchronous servo motors, providing closed-loop speed and position control over a shared 300 V DC bus. The unit combines power conversion and digital control in one housing, so the connected motor can respond accurately to command changes during indexing, contouring, and start-stop duty. Integrated bleeder resistors handle regenerative energy so braking events in assembly, packaging, and material-handling systems do not raise bus voltage above safe limits.

The power section supplies a continuous output of 30 A. The external link and internal circuitry both operate at 300 V, allowing the drive to share a common supply rail with other units. Regenerated energy is dissipated through an internal bleeder that can absorb 0.3 kW continuously and up to 5 kW during short peaks, which helps prevent overvoltage during rapid deceleration. Current is modulated at 18 kHz, which reduces audible motor noise and improves current resolution. This switching behavior supports smooth torque production during precision motion. The aluminum housing has an IP10 protection rating that helps prevent accidental finger contact while allowing ventilation. Heat is removed by passive dissipation through the chassis, so no moving cooling parts are required.

Full performance is maintained up to +45 °C. Above this temperature, the drive derates linearly until it reaches its operating ceiling of +55 °C. No output reduction is required below 1000 m above sea level. Because cooling depends on passive conduction, cabinet airflow must keep the heat sink within its temperature limit. Adequate spacing around the chassis helps warm air move away from the drive during continuous operation. This operating range suits enclosed control cabinets used for positioning, indexing, and synchronized motion tasks across varying installation sites.
