Product Description:
The DKS01.1-W100A-DS68-50-FW is an intelligent digital servo drive manufactured by Bosch Rexroth Indramat within the DKS Intelligent Digital Servo Drives series. It governs MDD synchronous motors by monitoring feedback from a DSF encoder and modulating transistor switching to achieve precise torque and velocity control. Designed for integrated machine cells, the unit accepts a fixed three-phase supply, conditions it through an internal DC link, and delivers regulated output to axes that require coordinated motion in packaging, conveying, or pick-and-place equipment. This closed-loop arrangement helps the drive respond quickly to changing load conditions while maintaining stable motor behavior during positioning and speed-controlled operation.
The drive can deliver a continuous output of 100 A, which is the maximum RMS phase current available to the motor under rated thermal conditions. Line power is supplied at 3 × 230 VAC, and this mains input is rectified to an internal bus voltage of 300 VDC, providing stored energy for acceleration events and load changes. Rapid deceleration sends excess kinetic energy into the integrated bleeder, where a peak dissipation capability of 18 kW helps prevent overvoltage on the DC link. Current is pulse-width modulated at 4 kHz, balancing control resolution with semiconductor losses while keeping acoustic output within a typical industrial range. The power section is intended for applications that need sustained servo performance without requiring a separate external braking module for normal deceleration events.
Total heat generated at maximum electrical load is 480 W, so cabinet airflow must remove that loss to keep internal components within their operating range. The housing carries an IP10 protection class, which means the drive should be installed inside a filtered enclosure with the prescribed clearance for convection and service access. Rated performance is available up to 45 °C ambient, while operation is permitted up to 55 °C with output derating. The installation environment should also account for altitude and storage conditions so insulation, bus components, and control electronics remain stable during transport, startup, and long-term machine use.
