Product Description:

The DKS01.1-W050A-DL04-00 belongs to the DKS Intelligent Digital Servo Drives series. As a servo drive, it supplies regulated three-phase power to compatible MDD synchronous motors and processes resolver feedback to close the position loop in automated handling and machining stations. The unit converts a fixed mains input into a pulse-width-modulated output while monitoring thermal, current, and DC-bus conditions during operation. In a motion system, it serves as the link between the incoming supply and the motor so commanded torque and speed can be corrected as the load changes. This supports repeatable axis response during indexing, feed motion, and positioning tasks.

Inside the drive, a brake chopper dissipates regenerated energy at a continuous level of 0.35 kW and can absorb peaks up to 9.4 kW, which helps prevent DC-bus overvoltage during rapid deceleration. The common bus is held at 300 V DC, and the mains section accepts 3 × 230 V AC (±10%) from a three-phase supply. A transistor bridge delivers up to 50 A of output current and switches at 4 kHz to reduce motor torque ripple. Resolver signals from the DSF sensor provide rotor position for real-time current vector control, and the switching stage shapes current delivery for stable motor response across changing speeds. Cooling is handled through heat dissipation, so the unit relies on cabinet airflow to remove 305 W of power loss at maximum load.

At full rated load, the input side draws 9.5 kVA, which affects feeder and circuit protection sizing. The housing meets IP10, so it limits access to live parts but does not protect against liquid ingress, making installation inside an enclosure necessary. Operation is permitted up to 1000 m above sea level without output derating. Above that altitude, current and power must be reduced to keep semiconductor temperatures within range. The drive supports three-phase input only and is intended for use with compatible MDD motors.
