Product Description:

The DKS01.1-W050A-DS01-02-FW is a digital servo drive produced by Bosch Rexroth Indramat within the DKS Intelligent Digital Servo Drives series. In an automation cell, it receives motion commands from a controller, modulates three-phase power, and directs that energy to a synchronous motor so position or speed targets are met with closed-loop precision. By combining control logic with the power section, the drive helps conserve cabinet space while supporting flexible use across different machine axes. This arrangement is suitable for positioning tasks that require stable response during changing load and speed conditions.

The power stage accepts a three-phase supply of 3 × 230 V (±10%) and rectifies it to a DC link held near 300 V. Continuous output capability is limited to 25 A, while short-term motion transients are handled by a peak current of 50 A. Commanded switching occurs at a PWM carrier of 4 kHz, which affects the electrical waveform delivered to the motor windings. Input frequency compatibility spans 50 Hz to 60 Hz, allowing operation on common industrial mains systems. Heat is removed through natural dissipation, and the internal bleeder converts regenerated energy into thermal loss to protect the DC bus. The IP10 housing is intended for open-rack installation inside a protected cabinet where airflow is available.

The bleeder element can absorb 0.35 kW continuously and tolerate surges up to 9.4 kW during rapid deceleration. Even at maximum mechanical load, the drive itself releases only 305 W of loss, excluding the bleeder, which helps support dense panel layouts with controlled thermal buildup. Ambient operation is permitted up to 55 °C and at elevations of up to 1000 m without derating. Noise emission is classified as standard for general factory lines. A 9.5 kVA line requirement sets the sizing of upstream fuses and contactors for the installation.
