Product Description:

The DKS01.2-W100A-DS71-00-FW belongs to the DKS Intelligent Digital Servo Drives series from Bosch Rexroth Indramat. It is a digital servo drive intended to regulate synchronous or induction motors in automated machinery, providing closed-loop speed and torque control while interfacing with higher-level motion controllers. The unit is suited for positioning axes and speed-controlled machine functions where repeatable motion and direct coordination with external control hardware are required inside a cabinet-based system.

This unit accepts a three-phase supply of 3 x 230 V AC, and that input feeds an internal rectifier that generates a stabilized DC bus of 300 V DC for the power stage. The output section can deliver up to 100 A, so motors with high peak torque demand can be started without external boosters. Pulse-width modulation at 4 kHz governs the IGBT bridge, balancing dynamic response with manageable switching losses. Overall power draw is capped at 11 kVA, allowing the drive to operate on standard factory feeders. Analog velocity or torque references are received as ±10 V DC signals, and the control section supports resolver or encoder feedback for closed-loop operation. Heat is removed through natural dissipation in the housing, and the protection class is IP10, so the drive must be installed inside a closed electrical cabinet.

The internal braking resistor handles regenerative surges continuously at 0.5 kW, and its bleeder network can absorb momentary peaks up to 18 kW without exceeding thermal limits. Even when the absorber is active, total drive losses remain within 480 W, which is useful when enclosure ventilation is being sized. Supply conductors may run up to 75 m before voltage drop affects performance, and motor lines can return instantaneous currents of 28 A to the bus during deceleration. The control interface at X9 uses 24 V DC, 625 mA to power the logic section, and the noise emission is standard. The stated cable lengths apply to both supply routing and motor connections during normal operation.
