Product Description:

The DKS01.1-W100A-DA02-00 is a digital servo drive manufactured by Bosch Rexroth Indramat for the DKS Intelligent Digital Servo Drives series. It operates as the power and control interface between a motion controller and an AC servo motor, providing regulated current and velocity commands for automated machinery on assembly lines, packaging stations, and material-handling axes. Its digital control architecture supports stable closed-loop motion in applications that require accurate response during changing load conditions.

This drive delivers a continuous output of 100 A, allowing it to handle high-torque motors without current starvation. It is designed for a three-phase supply of 3× 230 V AC, so it can be wired directly to common factory mains. Compatible grid frequencies from 50–60 Hz mean no conversion is required in most regions. Internally, the rectifier charges a DC link to 300 V, creating a stiff bus that feeds the inverter stage. The power devices switch at a carrier frequency of 4 kHz. This modulation rate affects the current ripple seen by the motor windings and influences acoustic noise and thermal stress on the transistors.

During deceleration, the braking resistor can dissipate regenerative energy continuously at 0.5 kW and absorb peaks up to 18 kW to keep the DC bus within safe limits. When operating at full load, the unit sheds 480 W of heat, so cabinet ventilation must accommodate that loss during operation. Its enclosure meets IP10, giving basic protection against accidental contact while requiring installation in a closed electrical cabinet. Full performance is maintained up to +45 °C, and operation is allowed up to +55 °C with output derating. Additional operating limits include service up to 1000 m elevation without derating, standard noise emission, and a maximum power draw of 11 kVA under peak load.
