Product Description:

The DKS01.1-W030B-RA01-02-FW is a digital servo drive manufactured by Bosch Rexroth Indramat in the DKS Intelligent Digital Servo Drives series. Acting as the power stage for a closed-loop axis, it converts single-phase mains energy into a controlled three-phase output for brushless servomotors used in pick-and-place, packaging, and material-handling cells. Integrated monitoring, braking, and diagnostic functions allow the drive to maintain tight velocity and position tolerances in industrial automation. Its control design is suited to repetitive motion tasks where stable acceleration and deceleration are required through frequent machine cycles.

This Version 1 unit operates from an input of 230 V AC ±10 % and delivers a rated motor current of 30 A. Inside, a rectifier charges the DC link to 300 V DC, while insulated-gate transistors switch that link at a carrier frequency of 18 kHz to produce the motor output waveform. A built-in bleeder resistor continuously removes excess regenerated energy up to 0.3 kW, which helps keep the DC bus below overvoltage conditions during normal braking. Resolver feedback supplies rotor position data for the control loop, and thermal management relies on passive heat dissipation through the housing instead of an external fan. The drive also has reduced noise emission, which helps limit audible switching noise in enclosed equipment.

During emergency stops or high-inertia deceleration, the bleeder can absorb peaks reaching 5 kW. The housing has an IP10 rating, which provides basic finger protection while still allowing cabinet airflow. For continuous duty, the drive tolerates ambient temperatures up to 55 °C when current derating is applied and operates without performance loss at elevations up to 1000 m. Storage is permissible between −30 °C and +85 °C, which helps protect the electronics during shipment or extended downtime. These operating conditions fit standard cabinet installations where airflow and ambient heat are managed appropriately.
