Product Description:

The DKS01.1-W050A-DL05-00 is an intelligent digital servo drive produced by Bosch Rexroth Indramat within the DKS Intelligent Digital Servo Drives series. This standalone unit controls synchronous and asynchronous servomotors and provides closed-loop speed and torque regulation in automated machine cells and handling lines. By combining power electronics, internal position control, and fieldbus interfacing in a single chassis, the drive reduces cabinet wiring and supports compact machine layouts. Its integrated design allows one unit to handle both power conversion and motion control tasks without additional external modules for basic operation.

The nominal mains supply is 3x 230 V ±10%, so the converter can connect directly to common factory power. That input is rectified to an internal DC bus of 300 V, which supplies the inverter bridge during operation. Under continuous duty, the power section delivers 25 A, while short intervals can reach 50 A when higher demand is present. The insulated-gate transistors switch at 4 kHz, balancing efficiency with acceptable current ripple for general automation use. Natural heat dissipation is used, and the IP10 protection class means the drive is intended for installation inside clean, enclosed cabinets.

The internal braking chopper diverts excess kinetic energy to a resistor that can dissipate 0.35 kW continuously and absorb surges up to 9.5 kW during rapid deceleration. At maximum mechanical load, the electronic stages release 305 W of heat, so panel ventilation must account for that thermal load. Ambient temperature can reach +45 °C without derating, and storage is permitted from -30 °C to +85 °C. Functional altitude is supported up to 1000 m above sea level without current reduction, and output must be reduced linearly above that point. Acoustic output is standard, and the 9.5 kVA demand is relevant when selecting the upstream protective device.
