Detailed Information on Schneider ELAU PMC-21105

1. Basic Configuration

• Brand & Series: Schneider Electric (ELAU brand, a core line for industrial motion control).
• Model Full Designation: PMC-2/11/05/000/01/00/01/00/00 (breakdown: PMC-2 = positioning motor controller type; 11 = series code; 05 = rated current indicator; subsequent segments indicate optional configurations).
• Rated Electrical Parameters:
  • Rated voltage: 3-phase AC 400V
  • Rated current: 5A
• Protection Class: IP20 (suitable for installation in enclosed control cabinets, protecting against solid objects ≥12.5mm).
• Special Features: Equipped with a discharge resistor (for safe energy release of the DC bus).
• Optional Modules:
  • I/O connector (position “I/O”): ANA-1 ±10V analog input module.
  • Communication connector (position “Communication”): No additional optional module.
  • Encoder connector (position “Encoder” on MC port): SCI-1 encoder interface module.
  • System connector (position “System” on MC port): No additional optional module.
• Memory Module: Equipped with MM-15 memory module for program storage and data backup.

2. Core Functional Features

• Integrated All-in-One Design: Combines flexible positioning control and digital motor drive into a single unit, eliminating the need for separate controllers and drives. This reduces system complexity, saves installation space, and lowers overall costs while ensuring stable signal transmission.
• Advanced Power Technology: Adopts 600V power technology with a built-in power filter for the DC bus. The DC circuits of multiple PMC-2 controllers can be switched in parallel, enabling scalable power configuration for multi-axis control systems.
• Multi-Processor Control Architecture: Features a 32-bit main processor + VECON dedicated motion control chip. The dual-processor design separates logic control and motion calculation tasks, supporting advanced control algorithms (e.g., precise position tracking, speed smoothing) to achieve high-accuracy position, speed, and torque control.
• Diversified Control Modes: Supports multiple control modes including PID closed-loop control, feedforward control, and position/speed/torque three-mode switching. It can adapt to different application scenarios (e.g., rigid positioning, dynamic synchronization).
• User-Friendly Programming & Debugging: Provides an intuitive programming interface and debugging tools, supporting IEC 61131-3 standard programming languages (ladder diagram, structured text, function block diagram, etc.). It allows for parameter setting, program writing, and real-time fault diagnosis, reducing development and maintenance costs.
• Rich Communication Interfaces: Equipped with multiple communication ports for seamless integration with upper-level systems (PLCs, HMI) and peripheral devices:
  • Serial ports: RS232, RS485 (for local device communication).
  • Ethernet port (TCP/IP) for high-speed data transmission.
  • Supports industrial protocols such as Modbus, Profinet, ensuring compatibility with mainstream industrial automation networks.

3. Technical Specifications

4. Application Fields

• Robotics: Precision positioning control for industrial robots (e.g., articulated robots, SCARA robots) in assembly, handling, and welding tasks.
• CNC Machine Tools: Spindle speed control and axis positioning for milling machines, lathes, and machining centers, ensuring high-precision machining.
