Product Description:
The DKR03.1-W200 is a digital intelligent AC drive controller produced by Bosch Rexroth Indramat within the DKR Drive Controllers series. It is intended for precise regulation of high-power servo or spindle motors in automated machinery. The controller converts incoming electrical power into regulated motor output so the connected axis can follow commanded speed and motion profiles with repeatable control. This drive supports coordinated motion and speed control in multi-axis systems used in packaging lines, metal-cutting centers, and printing equipment.
During continuous duty, the controller can supply 92 A of output current at a 4 kHz switching frequency, providing stable torque production for attached motors. Its continuous drive power reaches 35 kW for sustained motor operation. The unit accepts a three-phase supply of 3 x AC 400–480 V with a ±10% tolerance, allowing use on standard industrial power networks. This input range supports installation in industrial cabinets connected to common plant distribution systems. Internally generated losses add up to 1200 W of heat dissipation that must be removed from the cabinet. A separate control-stage supply of AC 230 V ±10% powers the logic, gating, and diagnostic circuits while remaining separate from the motor output stage.
For rapid acceleration, the inverter can momentarily deliver a peak phase current of 141 A, helping it overcome inertia or friction spikes. This higher peak current gives additional short-term torque support during starts, indexing moves, and rapid speed changes. The W200 model code corresponds to a current rating of 200 for heavy-duty applications. Thermal management uses a built-in air blower that forces ambient air across the heat sink, so no external liquid cooling loop is required. The housing, cabling lugs, and blower assembly give the unit a total mass of 49 kg, which should be considered when planning panel support.
