Product Description:

The DKS01.1-W100A-DA06-01-FW is a digital servo drive from Bosch Rexroth Indramat in the DKS Intelligent Digital Servo Drives series. It serves as the regulated power interface between a motion controller and a synchronous motor, converting three-phase mains energy into the precise voltage and current needed for closed-loop positioning. Integrated intelligence, parameter memory, and diagnostic functions allow the unit to streamline cabinet wiring while coordinating multi-axis tasks in packaging, printing, and material-handling installations.

Under nominal conditions the drive rectifies a 3×230 V AC supply to an internal bus of 300 V. This link feeds an IGBT bridge that switches at 4 kHz, providing smooth torque with controlled electromagnetic emission. Continuous output is rated at 100 A and can be maintained without derating up to the specified 1000 m elevation. During acceleration the current can momentarily reach the same 100 A peak, so upstream protection devices must be sized for 11 kVA, the unit’s stated demand at maximum load. Protection against accidental contact is limited to IP10; therefore, the open-frame module must be mounted inside a grounded control enclosure that supports heat dissipation. Noise emission is classified as standard, and thermal energy is removed by conduction across the rear heat sink and by internal heat-dissipation paths.

Regenerative energy is routed to an integrated bleeder resistor that tolerates 0.5 kW continuously and rises to 18 kW for short braking intervals. At the rated operating limit of +45 °C the electronics expel up to 480 W of heat, and the ambient limit extends to +55 °C before external derating is required. Storage is permitted to +85 °C, and operation remains unrestricted up to 1000 m elevation. The aluminum housing weighs 11 kg, a consideration for panel supports and vibration analysis. Firmware Version 1 synchronizes bus regulation with the 300 V link to keep braking and peak-current events inside the bleeder and power-loss limits.
