DKR02.1-W300N-BE56-01-FW

DKR02.1-W300N-BE56-01-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 and line series 02. The unit has design version 1, function module version 01, and a current rating of 300.

The controller uses a SERCOS command interface for communication with the control system. It supports digital servo and resolver feedback for receiving motor position and speed information. At a 4 kHz switching frequency, the drive provides approximately 55 kW of continuous power and 141 A of continuous current. Its peak current is 212 A for short-duration high-load operation.

The rated power input is three-phase AC at 400 to 480 V with a tolerance of ±10%. The control circuitry operates at 230 V AC with a tolerance of ±10%. The controller has no bleeder or brake chopper and uses a rigid DC bus. Cooling is provided by air from a built-in blower, which removes operating heat from the unit. Total heat dissipation is 1,800 W, and the controller weighs approximately 104 kg.
