DKR02.1-W200N-BA05-01-FW

DKR02.1-W200N-BA05-01-FW is manufactured by Bosch Rexroth Indramat as part of the DKR Drive Controllers series. It belongs to the digital intelligent AC product group, uses line series 02, and has design version 1. The analog command interface receives drive-control signals, while digital servo and resolver feedback support motor position and speed control. Its current rating is 200. The drive provides 120 A of continuous current and approximately 47 kW of continuous power at a 4 kHz switching frequency, with a peak current of 141 A.

The rated power input is three-phase AC at 400–480 V with a tolerance of ±10%. The control circuitry operates at 230 V AC with a tolerance of ±10%. A built-in air blower cools the unit, which has a total heat dissipation of 1,600 W. The rigid DC bus has no bleeder or brake chopper, so regenerative energy is not dissipated through an internal braking resistor circuit. The controller weighs approximately 104 kg.
