DKR02.1-W200B-BE56-01-FW

DKR02.1-W200B-BE56-01-FW is a Bosch Rexroth Indramat digital intelligent AC drive controller in the DKR Drive Controllers series. It belongs to line series 02, uses design version 1, and has function module version 01. The current rating is 200. Its SERCOS command interface provides real-time digital communication with compatible motion-control systems, while digital servo and resolver feedback support motor position and speed control.

The drive accepts a rated three-phase AC power voltage of 400 to 480 V with a tolerance of ±10%. Its control voltage is 230 VAC with a tolerance of ±10%. At a 4 kHz switching frequency, it delivers approximately 47 kW of continuous drive power and supports 120 A of continuous current. The peak drive current is 141 A for short periods of increased load.

An internal bleeder dissipates regenerated electrical energy through the brake resistor. The resistor provides 1.5 kW of continuous braking power and handles up to 240 kWs of braking energy. Cooling is supplied by a built-in air blower, which removes heat generated during operation. Total heat dissipation is 1,600 W. The controller weighs approximately 104 kg.
