Product Description:

The DKS01.1-W050A-DL14-01-FW is a digital servo drive created by Bosch Rexroth Indramat as part of the DKS Intelligent Digital Servo Drives series. The unit processes three-phase mains power, modulates it through an internal inverter, and supplies controlled motor power for synchronous or induction motors used in positioning tables, packaging axes, and material-handling gantries. Its control logic supervises current loops, velocity loops, and the internal bleeder circuit so regenerated energy from rapid deceleration can be handled inside the cabinet without an external braking resistor. This helps the axis follow changing speed commands while maintaining stable operation during acceleration, deceleration, and frequent direction changes. It is suited to machines that need repeatable motion and compact cabinet integration.

The integrated bleeder resistor can dissipate 0.35 kW continuously and tolerate a short-term peak of 9.4 kW. A continuous output current of 25 A is available for normal motion profiles, and the input supply is 3× 230 V AC (±10 %). Inside the converter, the rectifier and filter create an intermediate DC link of 300 V DC, which gives the power stage a stable source for pulse-width-modulated output. These electrical values describe how the drive manages steady motor demand and short braking events in normal machine operation. They also show that the unit is intended for applications where regenerated energy must be absorbed internally rather than routed to separate external hardware.

The unit may be used up to 1000 m above sea level without current derating, and at maximum device load the inverter releases 305 W as heat. The housing has an IP10 protection rating, which provides finger protection while allowing cabinet airflow. Command transistors switch at 4 kHz, which affects current control response and audible noise during operation. Ambient temperatures may reach 55 °C when load-dependent limits are observed, so enclosure ventilation remains important during continuous duty. The listed operating data also includes a rated current capability of 50 A, a standard noise emission class, and Version 1 status.
