DKR02.1-W200N-BA01-01-FW

DKR02.1-W200N-BA01-01-FW is a Bosch Rexroth Indramat digital intelligent AC drive controller in the DKR Drive Controllers series. It belongs to line series 02 and uses design version 1. The current rating code is 200. An analog command interface accepts control commands, while digital servo and resolver feedback provide motor-position and speed information. The unit uses function module 01.

The controller operates from a three-phase AC rated power supply of 400–480 V with a tolerance of ±10%. Its control voltage is 230 V AC with a tolerance of ±10%. At a 4 kHz switching frequency, it provides approximately 47 kW of continuous drive power and 120 A of continuous current. Peak drive current is 141 A. The rigid DC bus has no bleeder or brake chopper, so regenerative energy must be managed through the connected system. A built-in air blower cools the controller, which produces 1,600 W of total heat dissipation during operation. The unit weighs approximately 104 kg.
