DKR02.1-W200B-BE11-02-FW

DKR02.1-W200B-BE11-02-FW is a Bosch Rexroth Indramat unit in the DKR Drive Controllers series and belongs to the Digital Intelligent AC Drive Controller product group. It is design version 1 in line series 02, with a current-rating designation of 200. The rated power input is three-phase AC 400–480 V with a tolerance of ±10%, while the control circuitry operates at AC 230 V with a tolerance of ±10%.

At a 4 kHz switching frequency, the drive supplies approximately 47 kW of continuous power and 120 A of continuous current. Its peak drive current is 141 A for short periods of higher motor demand. The SERCOS command interface provides digital communication with the control system. Digital servo and resolver feedback support motor position and speed monitoring.

An internal bleeder dissipates regenerated energy through the brake resistor. The brake resistor handles 1.5 kW of continuous power and up to 240 kWs of braking energy. A built-in air blower cools the controller, and total heat dissipation is 1,600 W. The unit weighs approximately 104 kg.
