Product Description:

The DKS01.1-W050A-RL01-01-FW is a servo amplifier from Bosch Rexroth Indramat in the DKS Intelligent Digital Servo Drives series. As a digital servo drive, it links a motion controller to an AC servomotor by converting command signals into controlled current and voltage. This allows automated machinery to position loads quickly and repeatably in assembly lines, packaging systems, and material-handling axes. Because the amplifier handles both power conversion and closed-loop control, it supports accurate starts, stops, and speed changes during repetitive machine cycles. It is intended for servo applications that need responsive positioning and repeatable speed control under changing load conditions.

Its supply section operates from a DC bus of 300 V DC, giving the power stage the voltage headroom needed for rapid acceleration commands. During continuous operation, the inverter can deliver up to 25 A of motor current, while short-term demand can rise to 50 A. Input synchronism is supported across mains frequencies of 50–60 Hz. Braking energy is dissipated through a bleeder resistor rated for 0.35 kW continuously and up to 9.4 kW in short peaks. Resolver feedback is handled through the dedicated encoder interface, and cooling is provided by natural convection. The housing has an IP10 protection class, which suits installations where the unit is mounted inside a protected enclosure.

At full load, the converter can draw up to 9.5 kVA from the mains. Internal losses, excluding the bleeder stage, are limited to 305 W. Pulse-width modulation operates at 4 kHz, which balances switching losses and current ripple for typical servo applications. Safe operation is permitted up to +55 °C with appropriate derating, and installation at elevations up to 1000 m is allowed without output reduction. The unit is released as version 1, and its noise emission is standard for general factory environments.
