DKR02.1-W300B-BE56-01-FW

DKR02.1-W300B-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 a current rating code of 300. The controller uses a SERCOS command interface for communication with the control system. It supports digital servo and resolver feedback for motor position and speed control.

The drive operates from a rated three-phase AC power voltage of 400 to 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 supplies approximately 55 kW of continuous drive power and 141 A of continuous current. Its peak drive current is 212 A for short-duration load demands.

A built-in blower provides air cooling, and the controller has a total heat dissipation of 1,800 W. The internal bleeder dissipates regenerated energy through the brake resistor. This resistor has a continuous power rating of 1.5 kW and can absorb a maximum braking energy of 240 kWs. The unit weighs approximately 104 kg.
