Product Description:

The DKS01.2-W100A-DA01-00 is a digital servo drive manufactured by Bosch Rexroth Indramat for the DKS Intelligent Digital Servo Drives series. It interfaces with MDD motors and DSF feedback devices to create closed-loop positioning axes in automated assembly lines, packaging machines, and material-handling stations. By modulating its internal power stage, the unit supplies controlled three-phase power to the connected servomotor. This arrangement lets the drive receive position information from the feedback system and correct motor current in real time. It is suited for applications that require repeatable starts, stops, and speed changes under varying load conditions.

The drive accepts a three-phase supply of 3 × 230 V AC and internally generates a DC link of 300 V. It can deliver up to 100 A for rapid acceleration, while the continuous current limit is 50 A for sustained operation without excessive thermal rise. Current is switched at a carrier frequency of 4 kHz, which balances dynamic response with electromagnetic compatibility. The controller supervises gate signals and commutation data from the DSF encoder so motor phases stay aligned during speed changes and load variation. Stable commutation helps reduce torque ripple and keeps the axis responsive during short motion segments.

Up to 480 W of loss heat is removed through natural heat dissipation, and the housing remains within the IP10 protection class when panel mounted inside a cabinet. Natural heat dissipation means heat leaves the unit through its surfaces rather than through a dedicated fan system, which helps simplify cabinet airflow planning. Motor cables may reach 75 m without signal boosters when shielding and grounding are installed correctly. For process feedback, the analog monitor channel supplies 10 V DC, 4 mA, and the integrated brake-release relay carries 24 V DC, 1 A on its Bb contacts. Additional limits include a maximum drive load current of 28 A, a power requirement of 11 kVA, and a standard acoustic output profile. The unit is version 2 and supports current diagnostic functions.
