The ELAU PacDrive C400 A8 Controller is a compact industrial motion controller designed for synchronized automation applications requiring PLC logic and multi-axis motion control.

Based on a Celeron M 600 MHz processor and VxWorks real-time operating system, the C400 A8 provides deterministic control performance for packaging machines, assembly systems, and other high-speed automation equipment.

The controller supports up to 8 SERCOS servo drives and provides coordinated positioning functions, allowing multiple servo axes to operate with accurate synchronization.

The PacDrive C400 A8 integrates PLC programming according to IEC 61131-3 standards and supports multiple programming languages including Structured Text, Ladder Diagram, Function Block Diagram, Sequential Function Chart, Instruction List, and Continuous Function Chart.

The controller provides extensive communication capability including Ethernet, RS232, RS485, PROFIBUS DP, CAN, CANopen, and optional DeviceNet or EtherNet/IP interfaces.

With integrated digital I/O, analog I/O, touchprobe inputs, master encoder interface, and PacNet communication, the C400 A8 is suitable for complex machine automation systems requiring precise motion coordination.

According to the ELAU technical documentation, the C400 controller architecture combines PLC functions, motion control functions, SERCOS communication, and industrial fieldbus connectivity for production and packaging machines.
