Introduction to ELAU PMC-2/11/08/000/01/03/00/00/00
Product Description
The ELAU PMC-2/11/08/000/01/03/00/00/00 is a high-performance modular motion controller designed for precision automation in industrial machinery, particularly in packaging, printing, and material handling applications. As part of Schneider Electric’s ELAU range (now integrated into the Lexium Motion range), this controller combines advanced motion control capabilities with flexible I/O integration, making it ideal for complex multi-axis systems requiring synchronized operation and high throughput.
The model designation “PMC-2/11/08/000/01/03/00/00/00” breaks down its key specifications: “PMC-2” indicates a 2-axis base controller, “11” denotes a 110V AC power supply, “08” specifies 8 digital inputs, and the subsequent codes define I/O configurations, communication options, and hardware variants. This controller is engineered to deliver sub-millisecond synchronization between axes, supporting electronic gearing, camming, and interpolated motion profiles—critical for applications like label printing or robotic packaging where precise coordination is essential. Its modular design allows easy expansion with additional I/O modules or axis cards, adapting to evolving production needs.

System Introduction
The ELAU PMC-2/11/08/000/01/03/00/00/00 operates as the core of precision motion control systems, integrating four key layers:
- Motion Control Layer: The DSP executes high-speed control algorithms, calculating torque commands and position setpoints for each axis to maintain synchronization.
- I/O Layer: Digital inputs capture real-time sensor data (e.g., product presence), while outputs trigger actuators (e.g., grippers) in coordination with motion sequences.
- Communication Layer: CANopen facilitates seamless data exchange with servo drives, enabling precise speed and position control with minimal latency.
- Programming Layer: IEC 61131-3 compliance allows flexible logic design, from simple point-to-point moves to complex cam profiles for dynamic applications.
In a label printing machine, the controller synchronizes two axes: one driving the print head and another feeding label stock. It uses electronic gearing to maintain a fixed ratio between print speed and feed rate, ensuring labels align with printed content. Digital inputs from a photoeye detect label edges, triggering the controller to adjust feed velocity dynamically, while outputs activate inkjet nozzles at precise intervals—all coordinated within microseconds to maintain print quality at high speeds.
