Product Description:

The DKS01.1-W100A-DS01-02-FW is a digital servo drive produced by Bosch Rexroth Indramat within the DKS Intelligent Digital Servo Drives series. The unit converts three-phase mains power into a regulated DC bus and a pulse-width-modulated output that controls motor torque and speed in industrial automation cells. It forms the interface between the motion controller and the servo motor, delivering commanded current while monitoring temperature, voltage, and load conditions to maintain precise axis performance. Because power conversion and axis supervision are combined in one package, the drive can react quickly to changing motion commands. Its monitoring functions help the axis respond predictably if thermal or electrical conditions begin to move outside the normal operating range.

The power section accepts a supply of 3 × 230 V AC (±10 %) at 50–60 Hz and rectifies it to a DC link stabilized at 300 V DC. From this rail, the inverter switches at 4 kHz to shape output current for the motor. Under continuous duty, the drive can deliver 50 A, while short dynamic events can draw up to 100 A. For axes that need less than the full bridge rating, an internal regulator caps drive load current at 28 A. Digital Servo Feedback provides high-resolution position verification, heat is dissipated through the housing, and the noise emission is standard.

Energy returned to the DC link during deceleration is absorbed by an integrated bleeder resistor rated for 0.5 kW continuously and capable of 18 kW briefly, which helps prevent overvoltage trips. At full load, the drive can demand up to 11 kVA from the mains and dissipate 480 W as internal losses, so enclosure airflow must remove the generated heat. The product weighs 11 kg and is intended for ambient air between +5 °C and +45 °C. These operating limits should be observed during repeated acceleration and braking cycles so heat can leave the enclosure effectively during normal machine operation.
