DKR02.1-W200B-B

DKR02.1-W200B-B is manufactured by Bosch Rexroth Indramat as part of the DKR Drive Controllers series. It is a digital intelligent AC drive controller from line series 02 and uses design version 1. Its current-rating code is 200. The controller supports digital servo and resolver motor feedback, allowing it to receive rotor position and speed information from compatible motors.

The drive operates from a three-phase AC power supply rated at 400 to 480 V with a ±10% tolerance. Its control circuitry requires 230 V AC with a ±10% tolerance. At a 4 kHz switching frequency, the unit provides approximately 47 kW of continuous drive power and supports 120 A of continuous current. Its peak drive current is 141 A for short periods of increased load demand.

An internal bleeder dissipates regenerative energy through the brake resistor. The brake resistor handles 1.5 kW of continuous power and up to 240 kWs of braking energy. A built-in air blower cools the controller and removes heat generated during operation. Total heat dissipation is 1,600 W. The unit weighs approximately 104 kg.
