New Original MITSUBISHI MR‑J2‑40B 400W AC Servo Amplifier Drive
Product Overview
The MITSUBISHI MR‑J2‑40B is a brand‑new original 400 W SSCNET‑bus‑type AC servo amplifier from the MELSERVO‑J2 series. This digital servo drive adopts optical‑fiber SSCNET bus communication for high‑speed serial command transmission with upper‑level motion controllers. It is designed to drive matching Mitsubishi HC‑MF / HC‑SF‑series AC servo motors. Widely used in X‑Y positioning tables, pick‑and‑place devices, packaging machines, semiconductor assembly equipment and general‑purpose automation production lines. Marked as “New Original”, it means genuine factory‑produced unit with complete power modules, control circuit boards and full‑factory performance testing, free of refurbished or second‑hand assemblies. It converts 200‑class AC input power into precisely controlled three‑phase AC output to realize high‑precision position, speed and torque closed‑loop motor control.
Main Functions
- SSCNET optical‑fiber digital bus control: Receives motion commands via SSCNET bus, supports multi‑axis synchronous control and effectively reduces wiring workload.
- Multi‑control‑mode switching: Supports position control, speed control and torque control, selectable by internal parameter configuration.
- Real‑time auto‑tuning function: Automatically optimizes servo gain parameters according to mechanical load characteristics to improve system response and stability.
- Absolute encoder compatibility: Works with absolute‑value encoders when matched with backup battery module; repeated homing after power‑off can be omitted.
- Built‑in dynamic brake: Quickly brakes and locks motor shaft when servo turns off or fault alarm occurs.
- Rich fault diagnosis and alarm output: Detects various abnormal conditions, displays alarm codes on front‑panel LED and outputs alarm signals via external digital I/O for rapid on‑site troubleshooting.
- PC‑based parameter configuration and monitoring: Supports connection with dedicated servo configuration software for parameter editing, status observation and waveform recording.
- Multiple hardware protection functions: Provides over‑current, over‑voltage, overload, overspeed, encoder signal failure and electronic thermal protection for amplifier and motor safety.
Technical Characteristics
- Sine‑wave PWM current control algorithm, realizes low‑torque‑ripple stable motor operation even at low rotation speed.
- Optical‑fiber SSCNET communication suppresses electromagnetic interference in complex industrial field environments.
- Open‑frame cabinet‑mount structure with IP00 protection grade, intended for installation inside electrical control cabinets.
- Separated control‑circuit power supply design; main‑circuit power can be cut off independently for safer equipment maintenance.
- Built‑in regenerative processing circuit; external regenerative resistor can be connected for high‑inertia frequent deceleration applications.
- Abundant digital input‑output terminals for servo enable, interlock signals, alarm reset and status feedback.
- Compatible with incremental and absolute serial encoders of matched Mitsubishi servo motors.
- Meets CE safety standards for global industrial‑equipment deployment.
- Anti‑vibration suppression function reduces micro‑vibration under servo‑locked condition.
