DKR02.1-W300B-BE30-01-FW

DKR02.1-W300B-BE30-01-FW is manufactured by Bosch Rexroth Indramat as part of the DKR Drive Controllers series. It belongs to the digital intelligent AC drive controller product group, uses line series 02, and has design version 1. The current-rating code is 300, and function module version 01 identifies the installed module revision. Its SERCOS command interface supports communication with compatible control systems, while digital servo and resolver feedback provide motor position and speed information.

The controller accepts a rated power input of three-phase AC 400–480 V with a tolerance of ±10%. Its control circuits operate at AC 230 V with a tolerance of ±10%. At a 4 kHz switching frequency, the drive supplies approximately 55 kW of continuous power and 141 A of continuous current. Its peak drive current is 212 A for short periods of higher motor demand.

An internal bleeder dissipates regenerative energy through the brake resistor. The resistor provides 1.5 kW of continuous braking power and handles up to 240 kWs of braking energy. A built-in air blower cools the controller, supporting operation while the unit produces 1,800 W of total heat dissipation. The controller weighs approximately 104 kg.
