Product Description:

The DKC02.3-012-3-MGP-01VRS is an EcoDrive servo drive controller produced by Bosch Rexroth Indramat within the DKC Drive Controllers series. As a three-phase power stage, it converts DC-bus energy into regulated AC for synchronous or induction motors in automated machinery, enabling precise velocity and position loops coordinated by a higher-level motion control system. The unit supports multiple communication interfaces, allowing it to connect with common fieldbus networks in packaging lines, material-handling stations, and general-purpose gantries. This layout lets the controller serve as the electrical link between the machine control and the motor while maintaining stable closed-loop motion.

The drive supplies motors with a rated phase current of 12 A from a DC link stabilized at 300 V. Under continuous duty, the intermediate circuit can deliver 457 W, while brief acceleration events can draw up to 1469 W from the same bus. Motor voltage peaks are limited to 106 V, which suits low-inductance windings and helps limit insulation stress during rapid changes in output. An internal 100 Ω bleeder resistor and a 4.7 Ω soft-start resistor manage regenerated energy and inrush current, while the 2.2 A maximum line draw, three output phases, 1.4 kVA connected load, and altitude limit of 1000 m suit compact axes installed in standard industrial enclosures.

Thermal behavior is managed by limiting motor current to 2.5 A during standby and by restricting internal power loss to 400 W in continuous operation. With a mass of 1.4 kg, the controller can be mounted on light machine frames without adding much load, and its small mass is useful where installation space is limited. Reliable operation is permitted at ambient temperatures up to 55 °C with derated output, provided relative humidity remains below 90%. The brake output provides 36 VDC switching power for spring-applied brakes, and the design 3 soft-start network uses a 17 W resistor to reduce inrush during startup.
