DKC02.1-040-7-FW

DKC02.1-040-7-FW is a Bosch Rexroth Indramat EcoDrive in the DKC Drive Controllers series. It uses design version 1 and interface option 02, which provides a SERCOS interface for communication with the control system. The controller operates from three-phase mains and has a rated current of 40 A. Its selectable switching frequency is 4 or 8 kHz. Continuous current is 16 A at 4 kHz and 12.5 A at 8 kHz, allowing the operating current to be matched to the selected switching frequency.

The DC bus has a nominal voltage of 700 V and a capacitance of 0.15 mF for maintaining the intermediate circuit. It stores 15 Ws of energy and can accept up to 5.0 kWs of feedback energy during regenerative operation. The bleeder provides 0.15 kW continuously and 10 kW at peak to dissipate returned energy. Power dissipation without bleeder operation is 180 W, while the control supply consumes 0.7 A.

An internal blower provides forced-air cooling. The IP20 protection category guards against contact with fingers and objects larger than 12.5 mm but does not provide water protection. Installation is supported at elevations up to 1,000 m. The permitted humidity limits are 95% relative humidity and 25 g/m³ absolute humidity. The controller weighs 4.4 kg.
