Product Description:

The DKS01.1-W030B-DL05-01-FW is a servo drive manufactured by Bosch Rexroth Indramat for the DKS Intelligent Digital Servo Drives series. It governs AC servo motors in automated handling, packaging, and machining stations by converting fixed-frequency mains power into a variable-voltage DC link and finely modulated PWM output. In this role it synchronizes motor torque with motion commands from a higher-level controller while providing integrated bleeder circuitry to absorb regenerated energy during braking.

Its input stage accepts either single-phase or three-phase supply at 230 V AC ±10 %, which is rectified to a DC bus held at 300 V. The inverter section is rated for a continuous motor current of 30 A, enabling medium-frame servo motors to reach nominal torque without overheating. Switching devices operate at 18 kHz, so current ripple and audible noise are reduced compared to lower-frequency drives. Regenerated energy is dissipated by a bleeder resistor that can absorb 5 kW in short bursts; continuous absorption is capped at 0.3 kW to maintain thermal balance. These electrical limits define the dynamic braking capability during rapid deceleration or vertical load lowering.

For sustained service the housing is classified as IP10, and convective heat dissipation keeps internal temperature within the rated maximum of +45 °C; operation is allowed up to +55 °C with output derating. Performance remains unchanged up to 1000 m altitude, and storage is permissible between −30 °C and +85 °C for spare units. At maximum load the unit sheds 230 W as power loss, so cabinet ventilation must be sized for that heat. A DSF resolver interface supplies absolute rotor position data, noise emission is reduced by the high carrier frequency, and firmware version 1 matches the indicated hardware build.
