Product Parameters

• Manufacturer / Brand: Mitsubishi Electric.
• Series: MELSEC-Q Series Motion Module.
• Model: MM-PM41400CPM+4000.
• Control Axes: Capable of controlling multiple servo axes (e.g., 4 axes of interpolation control, with potential for more depending on the specific model variant and configuration).
• Control Methods: Supports point-to-point positioning, linear interpolation, circular interpolation, helical interpolation, and speed/position synchronous control.
• Communication Interface: Uses the high-speed SSCNET III/H (or compatible) fiber-optic network for deterministic, real-time communication with Mitsubishi MR-J4/J5 series servo amplifiers and motors.
• Programming: Programmed using dedicated motion control instructions (SFC, ladder logic with motion function blocks) within the GX Works3 engineering software.
• Positioning Points: Stores hundreds to thousands of positioning data points in its internal memory.
• I/O Points: Integrates dedicated high-speed I/O for motion-related signals like near-point dog, zero-point, and external input interrupts for precise positioning.
• Form Factor: A slot-in module designed for installation in a MELSEC-Q series PLC base unit.

Advantages and Features

• Seamless PLC Integration: Eliminates the need for a separate motion controller, providing unified programming, diagnostics, and data management within a single platform (GX Works3).
• High Precision & Speed: The SSCNET III/H loop provides ultra-high-speed communication with servos, enabling nanosecond-level synchronization and extremely precise multi-axis interpolation.
• Advanced Trajectory Control: Supports complex motion patterns including NURBS interpolation for smooth, high-accuracy contouring, ideal for cutting and drawing applications.
• Simplified Wiring: The fiber-optic SSCNET network dramatically reduces wiring complexity compared to traditional pulse-train systems, improving reliability and noise immunity.
• Comprehensive Diagnostics: Offers extensive troubleshooting tools within the software, allowing for real-time monitoring of servo status, following error, and alarm history.

Application Cases in Industry

• Semiconductor Manufacturing: Controls precision die bonders, wire bonders, and wafer handling robots requiring micron-level accuracy and complex multi-axis coordination.
• Advanced Machine Tools: Drives the synchronized axes of 5-axis CNC machining centers for complex contour milling and precision engraving.
• Printing & Converting: Manages the electronic line shafting (ELS) and registration control on high-speed flexographic and rotary printing presses.
• Industrial Robotics: Serves as the control core for customized Cartesian, SCARA, or delta robot cells used in assembly and packaging.
• Precision Testing Equipment: Controls the motion in automated optical inspection (AOI) systems and coordinate measuring machines (CMM).

Comparison with Competing Products

Direct competitors include multi-axis motion controllers from Beckhoff (TwinCAT NC PTP) or Bosch Rexroth (IndraMotion MLC). The MM-PM41400CPM+4000 differentiates itself through its deep, native integration with the Mitsubishi MELSEC-Q PLC ecosystem. Compared to a standalone motion controller from a brand like Delta Tau (now part of OMRON), the Mitsubishi module offers superior integration for logic and process control but may have a steeper learning curve for pure motion programming. Its primary advantage over pulse-based PLC motion modules (from Siemens or Rockwell) is the performance and simplicity of the fiber-optic servo network, enabling more axes and more complex synchronization on a single network.

Selection Suggestions and Precautions

• Selection Suggestions:
  1. Select the MM-PM41400CPM+4000 when designing a new machine requiring tight synchronization of 2-4 axes (or more) and you are already committed to or standardizing on the Mitsubishi Q-PLC platform.
  2. Carefully evaluate the required number of simultaneous interpolation axes, positioning points, and control cycle times against the module’s specifications.
  3. Ensure compatibility with the chosen servo amplifier series (MR-J4-B/J5-B with SSCNET III/H) and verify the total cable length constraints of the fiber-optic network.
• Precautions:
  1. Software Expertise: Programming the MM-PM41400CPM+4000 requires advanced knowledge of both GX Works3 and motion control concepts. Specialized training is highly recommended.
  2. Network Topology: The SSCNET III/H network requires a closed-loop (ring) topology. Careful planning of node order and fiber cable routing is essential for network integrity.
  3. Parameter Management: Motion parameters are stored in both the module and the servo drives. Consistent backup and management of all parameters are crucial for recovery and replication.
  4. Hardware Configuration: The module’s placement in the Q-PLC base unit and the allocation of its intelligent function module parameters must be correctly configured in the PLC’s system settings.
  5. Sourcing: Always verify the full model number suffix. Modules like the MM-PM41400CPM+4000 may have different firmware versions or regional variants. Purchase from authorized Mitsubishi Electric distributors.
