Product Description:

The DKS01.1-W030B-RL04-01-FW servo drive is manufactured by Bosch Rexroth Indramat and belongs to the DKS Intelligent Digital Servo Drives series. This single-axis unit converts fixed-frequency mains power into a modulated DC link that is used to produce controlled three-phase output for synchronous or induction motors. Within an automation cell, it governs torque, speed, and position while monitoring feedback so that machine movements follow the programmed motion profile with minimal deviation.

During operation, the drive draws a line supply of 230 V AC (±10%) and rectifies it to a DC bus level of 300 V DC. From this link, it generates pulse-width-modulated output at 18 kHz, a switching rate that helps reduce audible noise and smooth current waveforms. The device can source a continuous phase current of 30 A, allowing it to accelerate medium-frame servo motors without saturation. Excess kinetic energy is routed to an internal bleeder network that absorbs up to 5 kW in short bursts and 0.3 kW continuously, which helps prevent DC bus overvoltage. At maximum load, the electronic section dissipates 230 W, and passive heat sinks with cabinet airflow handle this loss so no additional drive-mounted fan is required.

An analog monitoring port provides real-time process data through a ±10 V DC signal, allowing oscilloscope capture of following error or torque demand without serial tools. The housing carries an IP10 classification, so the drive must be installed inside a cabinet while still allowing airflow for heat dissipation. Reliable service is permitted from +5 °C to +45 °C; above this range, current must be derated, although operation is maintained up to 55 °C. Operation is allowed at elevations up to 1000 m without output reduction, and the reduced noise emission helps limit sound levels in the installation area.
