Product Description:

The DKS01.1-W050A-RL02-00 is a digital servo drive produced by Bosch Rexroth Indramat and included in the DKS Intelligent Digital Servo Drives series. It converts fixed-frequency mains power into controlled output waveforms so connected synchronous motors can follow commanded velocity, torque, and position profiles in automated assembly, packaging, and material-handling systems. Its digital control section adjusts inverter output in real time so axis motion remains consistent during acceleration, steady running, and stopping. This makes the unit suitable for axes that require repeatable starts, stops, and speed changes within compact machine layouts.

At the power interface, the drive accepts 3x 230 V AC (±10%) from a three-phase supply and rectifies it to a regulated DC link of 300 V for the inverter stage. The power section can supply a continuous motor current of 50 A, and the required upstream capacity is 9.5 kVA at maximum load. Pulse-width modulation operates at 4 kHz, which balances switching losses with current ripple during normal operation. This arrangement gives the drive a stable internal supply for controlled motor response across typical industrial duty cycles. Losses that are not absorbed by the bleeder are removed by the specified cooling method, and humidity category F per DIN 40040 supports use in normal plant environments.

For regenerative energy, the internal bleeder can absorb 9.4 kW in short bursts and 0.35 kW continuously, which helps limit DC-bus overvoltage during rapid deceleration. The enclosure has an IP10 rating, so the drive should be installed inside a cabinet or other protected housing to restrict accidental contact with live parts. Installation is permitted at elevations up to 1000 m above sea level without derating. Regenerated energy is converted into heat inside the resistor circuit, which supports repeated braking events in standard production settings. Proper enclosure mounting also helps separate the drive from routine contact while allowing surrounding cabinet airflow to carry away internal heat.
