Working Principle
The DKC10.3-018-3-MGP-01VRS receives three-phase AC power and converts it to a regulated DC bus voltage. The integrated motion controller executes coordinated motion programs, receiving commands from a higher-level controller via fieldbus or operating autonomously based on its programmed logic. The controller processes encoder feedback from multiple servo motors to close position and speed control loops for each axis. PWM signals generated by the control processor drive the power modules, producing variable-frequency three-phase output to precisely control each connected servo motor. The electronic cam and gearing functions allow complex motion relationships between axes to be established without mechanical linkages. The fieldbus interface enables real-time exchange of process data, status information, and control commands with the plant automation system. Built-in diagnostics continuously monitor drive health, motor conditions, and communication integrity, reporting any anomalies for preventive maintenance.
