DKC01.1-040-7-FW

DKC01.1-040-7-FW is a Bosch Rexroth Indramat EcoDrive in the DKC Drive Controllers series. It is design version 1 and uses interface option 01 as its controller interface configuration. The unit supplies a rated current of 40 A and has a nominal DC-bus voltage of 700 V. Its DC-bus capacitance is 0.15 mF, which stores energy and helps stabilize the bus voltage. The bleeder responds at 820 V to dissipate excess DC-bus energy.

The control-voltage circuit consumes 0.7 A. The BB contact switches up to 1 A at 24 VDC, providing a low-voltage control contact. The DC-bus connection uses cable with a cross-sectional area of 4 mm² and supports a maximum cable length of 1.0 m. The controller requires 80 mm of minimum clearance, including 80 mm above and below, to provide space for cooling airflow.

The enclosure has an IP20 protection category, providing protection against contact with fingers and similarly sized solid objects but not against water. The unit measures 360 mm by 210 mm by 65 mm and weighs 4.4 kg. It can be installed at elevations up to 1,000 m. The maximum ambient temperature is +55ºC when operating with reduced nominal ratings. Environmental limits include 95% maximum relative humidity and 25 g/m³ maximum absolute humidity.
