Product Description:

Bosch Rexroth Indramat manufactures the DKS01.2-W100A-DL01-01-FW digital servo drive for use in closed-loop motion systems. As a member of the DKS Intelligent Digital Servo Drives series, the unit regulates torque and velocity for synchronous or induction motors through pulse-width-modulated power electronics. Integrated control logic exchanges data with higher-level controllers, enabling accurate positioning and speed regulation in automated assembly lines, packaging machines, and material-handling axes. Its control structure is intended for applications that require stable motor response during repeated starts, stops, and speed changes.

Electrically, the drive accepts a three-phase supply of 3× 230 V AC ±10% at 50 to 60 Hz and converts it to a stabilized DC link of 300 V DC. From this bus, the inverter delivers up to 100 A of continuous output current to the connected motor. Current is switched at a carrier frequency of 4 kHz, balancing control response with switching losses. Excess regenerative energy is routed to an internal bleeder resistor that can dissipate 0.5 kW continuously and withstand surges up to 18 kW, which helps keep the DC link within an acceptable operating range. Digital servo feedback from the motor closes the position loop, and the nominal device power loss remains limited under maximum load. The IP10 housing uses passive heat dissipation and does not require forced airflow.

The permitted operating environment ranges from +5 to +45 °C without derating, while operation up to +55 °C is possible at reduced output. Reliable operation is permitted up to 1000 m above sea level, and storage temperatures from -30 to +85 °C support normal transport and warehousing conditions. Noise emission is categorized as standard, and the protection class confines live parts for installation inside an electrical cabinet. The unit has an overall mass of 11 kg, which helps keep panel mounting manageable. Its aluminum heat sink and housing transfer internal heat to the surrounding air during normal operation.
