DKC05.3-016-7-FW

DKC05.3-016-7-FW is a Bosch Rexroth Indramat EcoDrive unit in the DKC Drive Controllers series. It is design version 3 and uses interface option 05, which provides a 9-pin male D-Sub connector for the interface connection. The controller has a rated current of 16 A and a peak current of 6 A at a 4 kHz switching frequency. At an 8 kHz switching frequency, it supports a maximum output frequency of 800 Hz.

The DC bus has a nominal voltage of 700 V and a nominal capacitance of 0.135 mF for energy storage and voltage stabilization. Its maximum charging current is 2 A, while the 240-ohm soft-start resistor limits inrush current during startup. The bleeder circuit supports a peak power of 2.7 kW for dissipating excess DC-bus energy. Control circuitry consumes 16 W, and the unit dissipates 80 W during operation. The controller measures 287 mm in height, 65 mm in width, and 229 mm in depth. Its mass is 3.2 kg.
