DKR02.1-W200B-BE30-01-FW

DKR02.1-W200B-BE30-01-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 controller has a current rating of 200. It provides 120 A of continuous current and approximately 47 kW of continuous drive power at a 4 kHz switching frequency. Its peak drive current is 141 A, supporting short-duration increases in motor demand.

The controller accepts a rated three-phase AC power voltage of 400–480 V with a tolerance of ±10%. Its control voltage is 230 V AC with a tolerance of ±10%. A SERCOS command interface provides real-time communication with compatible control systems. Digital servo and resolver feedback support motor position and speed monitoring.

A built-in blower provides air cooling, while total heat dissipation is 1,600 W. The internal bleeder dissipates regenerated energy through the brake resistor. The brake resistor has a continuous power capacity of 1.5 kW and can absorb up to 240 kWs of braking energy. The controller weighs approximately 104 kg.
