DKR04.1-W300N-BA05-01-FW

DKR04.1-W300N-BA05-01-FW is a Bosch Rexroth Indramat unit in the DKR Drive Controllers series and belongs to the digital intelligent AC drive controller product group. It is from line series 04, uses design version 1, and has a current rating of 300. Function module version 01 identifies the installed function-module configuration. The analog command interface receives analog control signals, while digital servo and resolver feedback provide motor position and speed information.

The drive delivers approximately 82 kW of continuous power and 185 A of continuous current at a 4 kHz switching frequency. Its peak current is 212 A for short-duration load demands. Rated power input is three-phase AC at 400 to 480 V with a ±10% tolerance, while the control circuitry operates at 230 V AC with a ±10% tolerance.

A built-in blower provides forced-air cooling to remove operating heat. Total heat dissipation is 2,250 W. The unit has no bleeder or brake chopper and uses a rigid DC bus, so it does not dissipate regenerative energy through an internal braking circuit. Its approximate weight is 150 kg.
