DKR02.1-W300N-BA35-01-FW

DKR02.1-W300N-BA35-01-FW is manufactured by Bosch Rexroth Indramat as part of the DKR Drive Controllers series. It belongs to line series 02 and uses design version 1. The series provides digital intelligent AC control for connected motors. Its current rating code is 300, identifying its current-capacity configuration.

The controller has an analog command interface for receiving control signals. It supports digital servo and resolver feedback for motor position and speed monitoring. The unit uses a rigid DC bus without a bleeder or brake chopper, so it does not dissipate regenerative energy through an integrated braking circuit. A built-in air blower provides forced-air cooling, while total heat dissipation is 1,800 W.

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%. At a 4 kHz switching frequency, the drive supplies approximately 55 kW of continuous power and supports 141 A of continuous current. Its peak drive current is 212 A, allowing it to accommodate short-duration current demand above the continuous rating. The controller weighs approximately 104 kg.
