Product Description:

The DKS01.1-W100A-DS11-02 belongs to the DKS Intelligent Digital Servo Drives series produced by Bosch Rexroth Indramat. It serves as a digital servo drive designed to command MDD synchronous motors, supplying closed-loop torque and speed control for automated machinery. In automation systems, it functions as the power stage between the supply and the motor, converting incoming electrical power into controlled motor current. The unit is Version 1 and uses passive heat dissipation rather than forced cooling, which suits cabinet layouts where airflow is limited.

The drive accepts a three-phase input of 3 x 230 V AC, which its internal rectifier converts into a DC bus maintained at 300 V DC. From this link voltage, the power stage can deliver a rated output of 100 A to the connected motor. Regenerative energy is managed by an internal bleeder assembly that can disperse 0.5 kW continuously and up to 18 kW in short peaks, preventing overvoltage during rapid deceleration. These values indicate the braking capacity available to the application and the amount of returned energy the drive can absorb during short stopping events.

On the mains side, the maximum line current is 28 A. The inverter switches at a pulse-width modulation frequency of 4 kHz, balancing acoustic performance with semiconductor losses that reach 480 W under full load. The housing has a protection rating of IP 10, so the installation environment must be clean and free of conductive dust. Continuous service is permitted up to +55 °C ambient, at elevations to 1000 m, and within Humidity Class F, while noise emission remains standard. Cabinet layout must account for heat dissipation, input current, and the clean installation environment required by the enclosure.
