DKR02.1-W300N-BE34-01-FW

DKR02.1-W300N-BE34-01-FW is manufactured by Bosch Rexroth Indramat as part of the DKR Drive Controllers series. It provides digital intelligent AC drive control. The controller belongs to line series 02, uses design version 1, and has function module version 01. Its current-rating designation is 300.

The command interface uses SERCOS for communication with the control system. Digital servo and resolver feedback provide motor position and speed data for closed-loop control. At a 4 kHz switching frequency, the drive supplies approximately 55 kW of continuous power and 141 A of continuous current. Its peak drive current is 212 A for short periods of increased load.

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