Product Description:
The DKC04.3-012-3-MGP-01VRS is an EcoDrive drive controller manufactured by Bosch Rexroth Indramat within the DKC Drive Controllers series. As a servo amplifier, it regulates current and voltage for Indramat synchronous or induction motors, allowing coordinated motion tasks in automated machinery and material-handling cells. The unit provides parameter storage and drive logic so that a PLC can command speed, torque, or position over fieldbus interfaces. Its compact size and plug-in terminals simplify cabinet layouts, while integrated diagnostics report faults and operating status to the control system. This arrangement supports machine installations that need a compact drive with onboard control functions and clear status reporting during operation.
The power section is designed around a DC link rated at 300 V, which sets the intermediate circuit voltage that the IGBTs modulate into three-phase motor output. With a nominal phase output of 12 A, the controller can continuously energize medium-frame servomotors without reaching thermal limits. Incoming supply demand peaks at 2.2 A, which is useful when sizing branch circuit protection and cabinet wiring. Internal losses generate up to 400 W of heat during continuous current, so forced-air ventilation is required to keep the heat sink below its setpoint. Communication is added through Interface Option 04, which provides selectable serial protocols alongside standard analog command inputs. These electrical values support use in compact motion systems where steady motor control and reliable heat removal are both required.
Mechanical layout follows Design 3, so the power terminals, control connectors, and heat sink positions match the third-generation EcoDrive mounting pattern. The control package is the multi-interface general-purpose version, and its revision level is 01, allowing parameter sets for point-to-point motion, simple gearing, and torque limiting. Continuous operation is permitted up to an ambient temperature of 40 °C, after which derating applies. At only 1.8 kg, the module adds little mass to a swing-out cabinet door. The low weight also helps when the unit is installed in compact control enclosures with limited panel space.
