It drives three-phase AC servo motors at a rated output voltage of three-phase AC 170 V, fed from a three-phase AC 200 V to 240 V, 50/60 Hz main circuit supply. The STO (Safe Torque Off) function per IEC/EN 61800-5-2 is built in, so you can remove drive torque without disconnecting the main power — useful for emergency-stop circuits or maintenance access where you need to keep the control logic alive. The command interface is a general-purpose interface, meaning it accepts standard analog or pulse-train position/speed/torque commands from a motion controller or PLC. No fieldbus module is integrated on this base variant — you add an option card if you need PROFINET, CC-Link, or similar. Mount the amplifier indoors, out of direct sunlight, in an atmosphere free of corrosive gas, flammable gas, oil mist, and excessive dust. Operating ambient temperature is 0 °C to 55 °C, non-freezing; storage range is -20 °C to 65 °C. Ambient humidity must stay at or below 90% RH, non-condensing. The unit is rated for installation up to 2000 m above sea level without derating. Above that, expect reduced dielectric strength and cooling — check the derating curve in the manual. Vibration resistance is 5.9 m/s² over 10 Hz to 55 Hz in each of X, Y, Z directions — typical for panel-mount servo drives, but if your machine sees sustained shock above that, consider vibration-dampening mounts.","metaTitle":"Mitsubishi MR-J4-700A Servo Amplifier, 37 A, 7 kW","metaDescription":"Mitsubishi MR-J4-700A servo amplifier, 37 A rated current, 7 kW motor output, 200 V class, STO safety function, active production, sourced to order.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Servo Drives"],"specifications":{"title":"MR-J4-700A","Output":"Rated voltage: Three-phase AC170 V","Elevation":"2000 m above sea level or less (Note 18)","Atmosphere":"Indoors (no direct sunlight), that there is no corrosive gas, flammable gas, oil mist, dust and dirt","Product no":"MR-J4-700A","description":"MR-J4 A Servo Amplifier","Product type":"MR-J4 A Servo Amplifier","Rated current":"37.0 [A]","Voltage class":"200V","Safety function":"STO (IEC / EN 61800-5-2)","Shipping Weight":"7.5 Kg","lifecycle_stage":"current","Ambient humidity":"Operation / save: 90% RH or less (non-condensing)","Command interface":"General-purpose interface","Estimated Lead Time":"Usually ships in 1-10 working days.","Overseas Compliance":"The correspondence to the international standards and laws, Standards Compliant page please refer to.","Vibration resistance":"5.9 M / s 2 , 10 Hz ~ 55 Hz (X, Y, Z each direction)","Servo amplifier Model":"MR-J4-700A-RJ","Environmental condition":"Ambient temperature: Operation: 0 ° C ~ 55 ° C (non-freezing), storage: -20 ° C ~ 65 ° C (non-freezing)","Motor rated output [KW]":"Seven","Main circuit power input":"Voltage and frequency (Note 1): Three-phase AC200 V ~ 240 V, 50 Hz / 60 Hz"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1,700.53 – $3,124.00","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/6660cd0768a60884ef7d5665ab4ba938.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the rated output voltage of the MR-J4-700A?","answer":"The rated output voltage is three-phase AC 170 V."},{"question":"What is the maximum elevation for installation?","answer":"The amplifier is rated for installation up to 2000 m above sea level without derating."},{"question":"Does the MR-J4-700A have a Safe Torque Off function?","answer":"Yes, it includes STO per IEC/EN 61800-5-2."},{"question":"What compliance documentation is available?","answer":"Overseas compliance (CE, UL, etc.) is handled per the brand's standards compliance page — request the specific declaration for your jurisdiction."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/mitsubishi/MR-J4-700A","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/mitsubishi/MR-J4-700A when reusing this data.
