Product Description:

The DKS01.1-W030B-DS11-02 is a digital servo drive produced by Bosch Rexroth Indramat in the DKS Intelligent Digital Servo Drives series. It regulates torque, speed, and position for AC servo motors in automated machinery, using internal microprocessor control to integrate with higher-level motion controllers. By converting the incoming AC supply to a controlled DC bus and then to PWM-modulated output, the unit provides closed-loop motion actuation in assembly cells, packaging lines, and material-handling stations.

It operates from a single-phase or three-phase supply at 230 V AC ±10%, and within this range the power section delivers a rated output current of 30 A to the motor windings. A pulse-width-modulated bridge switching at 18 kHz shapes the current, while the rectifier and intermediate circuit maintain an internal DC link at 300 V DC. During rapid deceleration, excess regenerative energy is routed to an integrated bleeder resistor that can absorb up to 5 kW for short intervals. Thermal energy created in the power electronics is removed through heat dissipation in the housing, so no additional fans are required. Operation is permitted in ambient moisture levels up to Humidity Class F under DIN 40040.

For continuous braking cycles, the resistor is limited to 0.3 kW, so applications requiring frequent stops must verify duty-cycle limits. The drive can be used at ambient temperatures up to 55 °C, although output must be derated as operating temperature rises, and performance remains unchanged up to 1000 m elevation. Its enclosure carries an IP10 protection rating, indicating open-frame construction intended for mounting inside a closed control cabinet. This enclosure style requires cabinet installation rather than open mounting on the machine frame. The control logic corresponds to Version 1.
