Mitsubishi Electric MR-J4-10A Series Servo System: Redefining Industrial Performance with 2.5kHz Hyper-Response Technology
— Pioneering Zero-Latency Manufacturing at the Speed of Innovation

Core Breakthrough: 2.5kHz Speed Loop Response – Setting a New Global Benchmark
The J4 series servo amplifiers integrate Mitsubishi Electric’s next-generation Hyper-Response Servo Engine, achieving an industry-leading 2.5kHz (2,500 cycles/sec) speed loop response frequency through hardware-level architecture innovation and algorithm optimization. This benchmark, 300% faster than conventional solutions, eliminates physical response limits in micron-level positioning, transient torque compensation, and high-frequency vibration suppression, empowering machines to operate beyond traditional performance thresholds.

Technological Core: Mitsubishi’s Proprietary “Lightning Engine” & 4.19M Pulse/rev Absolute Encoder Synergy

1. Ultra-Dimensional Computing Power
   • The dedicated high-speed servo control execution engine employs a multi-core parallel processing architecture, reducing command parsing latency to <0.04ms (40μs) – 8x faster than legacy systems.
   • The built-in AI-driven feedforward compensation algorithm performs 2,000-stage/sec dynamic trajectory prediction, eradicating time-lag errors in motion tracking.
2. Nanoscale Sensory Precision
   • Equipped with Mitsubishi’s 4,194,304 pulses/rev (22-bit) high-resolution absolute position encoder, achieving 0.000088°/pulse resolution – equivalent to detecting 0.0014mm displacement on a 1-meter-diameter circle.
   • Direct connection to the control engine via 100Mbps full-digital optical network bus ensures zero-packet-loss, zero-delay position feedback.
     

Industry-Transforming Applications: From Semiconductors to Aerospace

• Semiconductor Wafer Handling:
  • Achieves ±0.5μm positioning accuracy at 100mm/s, eliminating wafer scratches and alignment deviations.
• Precision Laser Machining:
  • Maintains ±1μm trajectory tracking accuracy at 500mm/s cutting speed when paired with 2.5kHz response.
• Collaborative Robot Joints:
  • Suppresses torque ripple to <0.03% at 1,000rpm, meeting stringent safety requirements for human-robot collaboration.

MR-J4-10A System-Level Advantages: Beyond Speed – Precision, Robustness, and Flexibility

• Anti-Disturbance Technology:
  • Dynamically eliminates mechanical resonance (200Hz and below) via adaptive notch filters and online vibration identification algorithms, eliminating manual tuning.
• Load-Adaptive Performance:
  • Handles 500% instantaneous overload and 0.1Hz–3kHz stiffness tuning, adapting to scenarios from lightweight precision to heavy-duty cutting.
• End-to-End Redundancy:
  • Triple-layer CRC verification + EDC error correction across encoder, drive, and bus ensures failure rates <0.001%.
    

Why Choose the MR-J4-10A ?

• Speed: 2.5kHz response = 2,500 state refreshes per control cycle, equivalent to full closed-loop control every 400 nanoseconds.
• Precision: 4.19M pulse/rev encoder + optical bus = 0.001mm trajectory reproduction capability, exceeding mechanical design limits.
• Efficiency: 300% faster response boosts machine throughput by 40% while reducing energy consumption by 25%.
