DKR02.1-W300N-BE30-01-FW

DKR02.1-W300N-BE30-01-FW is manufactured by Bosch Rexroth Indramat as part of the DKR Drive Controllers series. It uses digital intelligent AC drive control for regulating connected motors. The unit belongs to line series 02, uses design version 1, and has function module version 01. Its current rating code is 300.

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

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