DKR02.1-W200N-B

DKR02.1-W200N-B is a Bosch Rexroth Indramat unit in the DKR Drive Controllers series. It provides digital intelligent AC drive control and belongs to line series 02 with design version 1. The current rating code is 200. Its motor feedback supports digital servo and resolver feedback, allowing operation with motors using either feedback type.

The rated power input is three-phase AC at 400 to 480 V with a tolerance of ±10%. The control voltage is 230 VAC with a tolerance of ±10%, and the control-voltage power requirement is 200 VA. At a 4 kHz switching frequency, the controller supplies approximately 47 kW of continuous drive power and 120 A of continuous current. Peak drive current is 141 A. The maximum output frequency is 800 Hz at 4 kHz and 1600 Hz at 8 kHz.

The controller has no bleeder or brake chopper and uses a rigid DC bus. Its brake resistor ratings are 1.5 kW of continuous power, 90 kW of peak power, and 240 kWs of maximum braking energy. A built-in blower provides air cooling, while total heat dissipation is 1600 W. The IP20 protection category guards against contact with larger solid objects but does not provide water protection. The maximum ambient temperature under derated operation is 55ºC. The unit measures 1000 mm in height and 430 mm in width, and it weighs approximately 104 kg.
