DKR02.1-W200N-BA09-01-FW

DKR02.1-W200N-BA09-01-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 controller has a current rating of 200, with a continuous current of 120 A at a 4 kHz switching frequency. At the same frequency, it supplies approximately 47 kW of continuous drive power, while its peak drive current is 141 A for short periods of increased motor demand.

The rated power input is three-phase AC at 400 to 480 V with a tolerance of ±10%. Its control circuitry operates from 230 V AC with a tolerance of ±10%. An analog command interface accepts analog control signals, while digital servo and resolver feedback provide motor position and speed information. The unit has no bleeder or brake chopper and uses a rigid DC bus.

Cooling is provided by air from a built-in blower, which removes heat generated during operation. Total heat dissipation is 1,600 W, and the controller weighs approximately 104 kg.
