Product Description:

The DKS01.1-W030B-DL40-01-FW belongs to the DKS Intelligent Digital Servo Drives series developed by Bosch Rexroth Indramat. In automated production lines, this unit governs torque, velocity, and position loops for AC servo motors, allowing machine tools, pick-and-place axes, and packaging stations to follow command profiles with closed-loop precision. Closed-loop operation helps the connected motor respond consistently during acceleration, steady running, and stopping. This makes the drive suitable for coordinated axis control where repeatable motion and stable servo response are required under changing load conditions.

The drive accepts a nominal AC supply of 230 V AC and operates on line frequencies up to 60 Hz. An internal rectifier charges the DC link to 300 V DC, while pulse-width modulation at 18 kHz shapes the motor current to reduce audible noise. Both the rated and peak output current are listed as 30 A, so the same inverter section supports continuous motion and short acceleration periods. Cooling uses forced heat dissipation through the housing, the noise emission is reduced, and the unit is built to Humidity Class F. It is Version 1, and Protection Class IP10 indicates installation inside a control cabinet where the enclosure provides additional guarding.

Regenerated energy during braking is absorbed by an integrated resistor that can dissipate 0.3 kW continuously and handle surges up to 5 kW during rapid stops. The allowable operating temperature reaches 45 °C before derating begins, and the absolute limit is 55 °C. Storage is permitted up to 85 °C, and operation is allowed at elevations up to 1000 m without current reduction. Above that altitude, thermal and dielectric margins must be recalculated. The integrated braking path handles routine deceleration energy inside the drive, while cabinet airflow, ambient temperature, and installation height all affect the available thermal headroom.
