Product Description:

The DKS01.1-W030B-RS01-03-FW is manufactured by Bosch Rexroth Indramat as part of the DKS Intelligent Digital Servo Drives series. It functions as a servo drive that converts mains power into regulated motor current so motion axes can follow position and velocity commands from a PLC. Resolver feedback from the connected motor is processed through its RSF interface, and the integrated bleeder circuit dissipates return energy to keep the internal DC link within safe limits during deceleration in automated packaging, handling, or assembly machinery.

This drive accepts a three-phase supply of 3x 230 V AC ±10% or a single-phase feed when lower power is required. In operation, it can deliver a continuous output of 30 A, and current is derived from an internal link maintained at 300 V DC. Pulse-width modulation switches at 18 kHz, a frequency chosen to reduce audible noise and improve current resolution. During regenerative events, the bleeder resistor converts surplus energy into heat at up to 0.3 kW, preventing DC-bus overvoltage while minimizing stress on external components. Overall thermal control relies on natural heat dissipation through the housing, and the drive is intended for reduced acoustic emission in operator work areas.

Short bursts of regenerative energy are tolerated at a peak bleeder load of 5 kW, which helps protect the DC link when heavy loads stop abruptly. Power loss at maximum throughput is limited to 195 W, which simplifies cabinet cooling calculations. The housing carries a protection rating of IP10, so it must be mounted inside a closed electrical enclosure while remaining accessible for airflow. Reliable performance is maintained up to a derated ambient temperature of +55 °C, provided installation elevation stays below 1000 m and relative humidity conforms to class F per DIN 40 040. Long-term storage is allowed between -30 °C and +85 °C without degrading the drive electronics.
