Product Description:

The Bosch Rexroth Indramat DKS01.1-W100A-DS29-01 belongs to the DKS Intelligent Digital Servo Drives series. As a closed-loop drive, it regulates the torque and speed of servomotors used in automated assembly lines, packaging machines, and material-handling axes. By combining power electronics, control logic, and digital servo feedback from the attached motor, the unit supplies precisely metered current to maintain position accuracy under dynamic load changes. This arrangement helps the drive respond quickly to changing loads during acceleration, braking, and steady-speed operation.

The drive's internal bleeder resistor dissipates regenerated energy at a continuous level of 0.5 kW, and it can accept short bursts up to 18 kW to prevent DC-bus overvoltage during rapid motor deceleration. A continuous output current of 50 A is supplied from a three-phase mains input rated at 3x 230 V (±10 %), which matches factory power grids at 50 or 60 Hz. Inside the converter, the bus is stabilized at 300 V DC so the control section can modulate torque without voltage sag. Heat generated by the IGBTs is removed by a heat-dissipation plate, eliminating the need for forced airflow. The device uses digital servo feedback protocols, allowing high-resolution encoder data to close the velocity loop with minimal phase lag. That braking-energy handling helps limit overvoltage when the motor returns energy to the DC bus.

Peak inrush events are covered by a permissible current of 100 A, while the installation must be sized for a mains demand of 11 kVA. Pulse-width modulation operates at 4 kHz, which balances switching losses with acoustic performance, and the noise emission remains at a standard level suitable for control cabinets. The housing has an IP 10 protection rating, so it provides only basic protection against accidental contact and must be mounted inside an enclosure. Its height is 373 mm, its width is 170 mm, and its depth is 260 mm, which allows stacking with adjacent DKS modules. That output level suits symmetrical duty cycles, and heat dissipation combined with cabinet airflow maintains component temperature within limits.
