Product Description:

The DKS01.1-W100A-DS41-00-FW is a digital servo drive produced by Bosch Rexroth Indramat within the DKS Intelligent Digital Servo Drives series. It is intended to regulate synchronous or induction servo motors in automated machinery, providing closed-loop velocity and torque control through pulse-width-modulated output stages. By converting a three-phase mains supply into a controlled DC link and modulating that energy to the motor, the unit enables precise axis positioning, coordinated motion, and repeatable cycle times in packaging lines, material-handling gantries, and similar equipment. That control structure supports synchronized machine movements where repeatability matters from cycle to cycle.

The drive accepts a three-phase supply of 3 × 230 V AC (±10%) at an input frequency of 50 to 60 Hz. Internally, it maintains a DC bus level of 300 V that feeds an inverter bridge rated for a continuous phase current of 100 A. This arrangement lets the power stage supply stable motor current during continuous operation and fast load changes. Switching occurs at a carrier of 4 kHz, balancing current ripple against thermal stress on the power semiconductors. During acceleration and regenerative braking, excess energy is routed to a bleeder resistor, so the inverter can demand up to 11 kVA from the supply under maximum dynamic loading. Heat generated by semiconductor switching is removed through direct heat dissipation, and operation is limited to altitudes up to 1000 m so cooling remains effective.

The energy diverted to the braking resistor can momentarily reach 18 kW, while overall conduction and switching losses peak at 480 W when the drive is fully loaded. This braking capacity supports short regenerative events that occur during rapid deceleration. An enclosure classification of IP10 indicates finger-safe openings but no protection against fluids, so the unit must be installed inside a closed electrical cabinet. The cabinet must provide forced airflow, and the drive has a mass of 11 kg with a storage range of -30 to +85 °C.
