Product Description:

The DKS01.1-W050A-DS63-01-FW is a drive unit produced by Bosch Rexroth Indramat for the DKS Intelligent Digital Servo Drives series. As a closed-loop controller, it regulates torque and speed for brushless servo motors used in positioning tables, pick-and-place systems, and similar automation cells. In that role, it supports repeatable motion on axes that require stable response during starts, stops, and speed changes. The product connects to a higher-level PLC and uses a DSF encoder interface for feedback. It also provides a monitor output for diagnostic status, simplifying system health checks.

The drive accepts a three-phase supply of 3× 230 V AC (±10%) at an input frequency of 50–60 Hz, so the same model can operate on standard factory mains without tap changes. Internally, the rectifier charges a 300 V DC bus that feeds the IGBT inverter stage, allowing quick current rise and precise field-oriented commutation. During normal operation, the power section can deliver a continuous phase current of 50 A, so motors that draw up to that value can be driven without derating. When accelerating high-inertia axes, the cabinet must supply up to 9.5 kVA, a figure used for breaker sizing and cable selection. Heat generated by the semiconductors is removed by forced air across an external heat sink, helping keep device temperature within the limits of an IP10 enclosure.

Operation is permitted at ambient temperatures up to +55 °C, and higher temperatures require load derating. Installation heights can reach 1000 m without power reduction, and motor leads may extend to 75 m when Indramat-shielded cable is used, which provides flexibility in large gantry frames while preserving signal integrity. At maximum load, the drive expels 305 W of heat, which is important for cabinet airflow calculations during continuous-duty operation. The standard noise emission rating helps limit acoustic output in industrial spaces. The unit is mechanical version 1.
