DKR03.1-W100B-BE30-01-FW

DKR03.1-W100B-BE30-01-FW is a Bosch Rexroth Indramat digital intelligent AC unit in the DKR Drive Controllers series. It belongs to line series 03, uses design version 1 and has function module version 01. Its current rating is 100. The drive supplies approximately 26 kW of continuous power at a 4 kHz switching frequency, with a continuous current of 71 A and a peak current of 71 A.

The rated power input is three-phase AC 400 to 480 V with a tolerance of ±10%, while the control circuitry operates at AC 230 V with a tolerance of ±10%. A SERCOS command interface supports communication with the control system. Digital servo and resolver feedback provide motor position and operating data for closed-loop control.

The controller uses forced-air cooling from a built-in blower to remove operating heat. Its total heat dissipation is 900 W, which indicates the thermal load that the installation must manage. An internal bleeder dissipates regenerated energy through the brake resistor. The brake resistor supports 1 kW of continuous power and a maximum braking energy of 150 kWs. The unit weighs approximately 49 kg.
