Product Description:

The DKS01.1-W050A-RL03-01-FW is a digital servo drive produced by Bosch Rexroth Indramat within the DKS Intelligent Digital Servo Drives series. Engineered to regulate torque, speed, and position of synchronous motors in automated machinery, it forms the link between PLC motion commands and the electromechanical output stage. The unit integrates power conversion and resolver feedback processing so axis controllers receive real-time shaft data for closed-loop control in packaging lines, material-handling cells, and assembly equipment. This arrangement supports precise response during repeated starts, stops, and speed changes without requiring separate external feedback hardware.

To match European three-phase supplies, the drive accepts 3×230 V line voltage within a ±10% tolerance and operates over an input frequency window of 50–60 Hz. At full load it can deliver a phase current of 50 A, while its output is switched through an IGBT bridge at 4 kHz carrier frequency for controlled motor operation. The internal intermediate circuit operates at 300 V DC, which supports rapid energy exchange with the connected motor during acceleration and braking. Resolver signals are processed through the built-in interface, so no external converter card is required. Continuous operation is permitted from +5 °C to +45 °C, and derating allows use up to 55 °C when needed.

During dynamic deceleration, the integrated bleeder channel converts regenerative energy and can absorb peaks of 9.4 kW while sustaining 0.35 kW continuously. Under maximum electrical loading, the housing dissipates 305 W of heat loss, and the apparent power draw reaches 9.5 kVA. The enclosure is rated IP10, so the unit must be installed inside a ventilated control cabinet and used below 1000 m above sea level. Storage is permitted from −30 °C to +85 °C. Proper cabinet airflow helps remove heat during operation and supports stable performance in enclosed automation systems.
