Product Description:

Bosch Rexroth Indramat developed the DKS01.1-W030B-RS01-01 for the DKS Intelligent Digital Servo Drives series. This unit is a digital servo drive that rectifies and modulates incoming mains power so it can command brushless servo motors in pick-and-place cells, feeders, and general motion modules. The resolver feedback interface supplies rotor angle data to the internal controller, allowing synchronized switching of the output stage during closed-loop operation. By combining power electronics and control logic in one housing, the drive reduces panel wiring and simplifies system setup.

The drive accepts a single-phase or three-phase supply of 230 V AC ±10%. At maximum load, it draws 16 A on a single-phase line, while three-phase operation lowers the input current requirement. The rectified link creates a DC bus that supports an output rated at 30 A. Current is delivered to the motor through pulse-width modulation operating at 18 kHz, which helps limit torque ripple and reduce audible noise. A diagnostics jack provides a differential control signal of ±10 V DC, allowing external monitoring of operating variables without interfering with the control loops.

Passive heat dissipation is handled through the aluminum chassis, which removes heat without a built-in fan. An integrated bleeder resistor dissipates regenerated energy at 0.3 kW continuously and can absorb peaks of 5 kW during rapid deceleration. The same diagnostics port can source up to 4 mA for external indicators or monitoring devices. The housing carries an IP10 protection class, so the drive must be installed inside a control cabinet. Operation is permitted at ambient temperatures up to 55 °C and elevations up to 1,000 m, and storage is permitted from -30 °C to +85 °C. Unobstructed airflow around the heat sink is required for normal thermal performance.
