DKR02.1-W300N-BA08-01-FW

DKR02.1-W300N-BA08-01-FW is a Bosch Rexroth Indramat digital intelligent AC drive controller in the DKR Drive Controllers series. It belongs to line series 02 and uses design version 1. The current-rating code is 300, and function module version 01 identifies the installed function module configuration. Its analog command interface receives analog control signals, while digital servo and resolver feedback provide motor position and speed information.

The controller accepts a rated power input of three-phase AC 400–480 V with a tolerance of ±10%, supplying the power stage for motor operation. Its control circuits operate at AC 230 V with a tolerance of ±10%. At a 4 kHz switching frequency, the drive provides approximately 55 kW of continuous power and 141 A of continuous current. Peak drive current is 212 A for short-duration load demands.

A built-in blower provides forced-air cooling, and total heat dissipation is 1,800 W. The rigid DC bus has no bleeder or brake chopper, so the controller does not internally dissipate regenerative energy through a braking resistor. The unit weighs approximately 104 kg.
