Product Description:

The DKS01.1-W030B-DL03-00 is a digital servo drive produced by Bosch Rexroth Indramat within the DKS Intelligent Digital Servo Drives series. Designed for closed-loop motion control, the unit supplies modulated power to matched servo motors while monitoring encoder feedback to maintain commanded speed and position. It accepts both single-phase and three-phase line supplies, rectifies the incoming power, and regulates the internal bus so rapid acceleration, controlled braking, and energy recovery can be carried out in industrial automation cells. This control method helps the drive correct load-related deviations during operation. It is suited for machinery that requires stable servo response during repeated speed changes and positioning moves.

The drive accepts 230 V AC single-phase power or 3 x 230 V AC three-phase power with a line tolerance of ±10 percent, and both inputs are converted to 300 V DC on the internal bus. Continuous output is limited to a rated current of 30 A, and the switching frequency of 18 kHz helps reduce motor acoustic noise. During deceleration, the bleeder resistor dissipates 0.3 kW continuously and up to 5 kW for short intervals to prevent DC overvoltage. In normal operation, the electronics dissipate only 230 W, so airflow around the drive should remain unobstructed. Digital Servo Feedback encoder signals are processed directly by the control section for precise commutation, speed regulation, and diagnostic reporting.

Protection class IP10 means the drive blocks only large foreign objects, so it must be installed inside a control cabinet. The unit can operate at ambient temperatures up to 55 °C and at elevations up to 1000 m before current derating is required. Under dynamic load, the power module may draw 4.5 kVA, while the continuous rating reaches 15 kVA at full duty. The drive meets humidity class F and operates with reduced noise emission when mounted in a standard enclosure. The unit is version 1.
