Product Description:

The DKS01.1-W030B-DA01 belongs to the DKS Intelligent Digital Servo Drives series from Bosch Rexroth Indramat. As a digital servo drive, it works with MDD synchronous motors to control torque, speed, and position in automated stations. The unit receives motion references through an analog incremental emulator interface and returns position data through digital servo feedback, enabling closed-loop control for assembly robots, packaging axes, and similar equipment that requires precise electrical actuation. This feedback arrangement helps the control loop correct load changes quickly and keep axis movement consistent during acceleration, indexing, and speed regulation.

The drive accepts an input supply of 1x or 3x 230 V AC and rectifies the line to maintain a DC bus of 300 V. Its IGBT stage switches at 18 kHz, which helps smooth motor current and reduce audible noise from the power section. Under rated conditions, the power section can supply 30 A continuously to the attached motor, supporting repeated starts and stops on dynamic axes. The housing has an IP10 protection rating, so the unit must be installed inside a control cabinet, and passive heat dissipation removes losses from the power electronics.

An internal bleeder resistor absorbs regenerative energy and can handle 0.3 kW continuously with momentary peaks up to 5 kW during deceleration. This allows excess energy from braking loads to be dissipated inside the drive instead of raising DC bus voltage too quickly. A diagnostic terminal provides a stable reference of 10 V DC for external sensors or encoders, and the reference output supports signal devices that need a consistent low-voltage source. The drive can operate in ambient temperatures up to 55 °C at elevations not exceeding 1000 m, provided airflow around the fins remains unobstructed. The unit is version 1.
