Product Description:
The DKR03.1-W200N-BA12-01-FW drive controller is manufactured by Bosch Rexroth Indramat within the DKR Drive Controllers series. It belongs to the Digital Intelligent AC Drive Controller group and is intended to regulate large servo axes in machining centers, presses, and automated handling systems. The unit ties into a rigid DC bus and omits an internal brake chopper, so excess regenerated energy must be handled by external dissipation hardware. By processing velocity and position information from digital servo and resolver sensors, it delivers closed-loop motion control that follows commands from the machine control system and supports accurate regulation during changing load conditions.
Drive commands enter through an analog interface, allowing ±10 V speed or torque references to be supplied directly from a PLC or CNC. At a switching frequency of 4 kHz, the power stage can furnish a continuous output of 92 A, which corresponds to roughly 35 kW of mechanical power for the connected motor group. The internal electronics are energized from a dedicated AC 230 V ±10% control supply, keeping diagnostics active even when the main bus is isolated. Temperature is managed by a built-in air blower that moves cabinet air across the heat sinks without external ducting or water circuits. This arrangement supports heat removal within the cabinet and keeps the cooling method straightforward for enclosed drive installations.
For short-duration transients, the controller can supply up to 141 A, supporting rapid acceleration while staying within the permitted line voltage window of 3xAC 400–480 V ±10%. When mounted in an enclosure, it releases about 1200 W of heat, a value that must be considered when sizing panel ventilation or air conditioning. The housing weighs 49 kg, so the mounting structure must support a substantial installed load. The controller is in line 03, design version 1, and function module 01 of the DKR family. These identifiers indicate the specific product generation used for this drive type.
