Product Description:

The DKS01.1-W030B-DS11-01 is a digital servo drive produced by Bosch Rexroth Indramat within the DKS Intelligent Digital Servo Drives series. It interfaces with Indramat synchronous motors and encoder feedback to regulate torque, speed, and position in automated handling, packaging, and machine-tool axes. By combining power electronics, signal processing, and drive control in one enclosure, the unit serves as the central actuator interface between a motion controller and the mechanical load.

During continuous duty, the drive demands an apparent input power of 4.5 kVA, which sets the minimum rating for circuit breakers and supply transformers. At its rated load, the output stage can deliver 30 A of motor current, allowing mid-frame motors to reach their nominal torque without saturation. Current is modulated through an IGBT bridge that switches at 18 kHz, yielding fine current resolution while keeping acoustic noise low. Regeneration energy is dissipated by an internal bleeder resistor that absorbs 0.3 kW continuously and tolerates surges up to 5 kW, protecting the shared DC bus from overvoltage during rapid deceleration or lowering moves.

The single-phase or three-phase supply accepts 230 VAC with a ±10% tolerance, which simplifies installation in plants that standardize on 230 V mains. Inside the housing, the rectifier and switching devices charge a DC link to 300 V DC, and this energy is transferred to the motor phases through pulse-width modulation. Ambient temperature can reach 55 °C when output derating is applied, while operation without derating is limited to 45 °C. The enclosure has an IP10 rating, so it is intended for use in closed cabinets with forced airflow. Installation altitude is limited to 1000 m to reduce dielectric stress on the power section, and safe storage is permitted between -30 °C and 85 °C.
