Newport MM4000 Motion Controller

The Newport MM4000 is a four-axis motion controller designed to command stepper motors and DC servo motors with precise positioning and velocity control. It executes linear-interpolated and non-synchronized movements under closed-loop control via incremental encoder feedback, employing a numerical feed-forward PID control loop with a 1 ms sampling period. The system operates autonomously through its front panel interface and interactive menus, executes stored programs from internal memory, or integrates into larger systems via remote command modes.

– Technical Specifications

• Axes: Up to 4 independent axes
• Motor Types: DC servo motors and stepper motors
• Control Architecture: Numerical feed-forward PID loop
• PID Sampling Period: Approximately 1 ms
• Feedback: Incremental encoder support for closed-loop operation
• Motion Types: Linear interpolated and non-synchronized movements

– Key Features

• Dual operational modes: standalone autonomous operation and program execution from internal memory
• Real-time control via front panel display with interactive menus
• Remote command interface for system integration
• LabVIEW driver support for National Instruments integration
• AC input auto-ranging (110 V / 220 V)

– Interfaces & Communication

• RS-232 serial interface
• GPIB (IEEE-488) connectivity

– Compatibility & Integration

The MM4000 is compatible with Newport’s 850G Series actuators. Implementation requires proper configuration of driver cards and servo parameter adjustment to match specific actuator characteristics. Its communication ports enable integration with test systems, data acquisition platforms, and automation frameworks.
