Mitsubishi MR-JE-70C AC Servo Amplifier 750W | Replacement, Equivalent & Selection Guide
The Mitsubishi Electric MR-JE-70C is a 750W single-axis AC servo amplifier from the MELSERVO-JE series, designed for general-purpose motion control applications. It accepts a 3-phase or single-phase 200–240 V AC input and communicates via SSCNET III/H (CC-Link IE Field Network compatible) for high-speed, noise-immune fiber-optic network control. This page provides full technical specifications, compatible replacement models, application guidance, and a structured selection guide to help engineers and procurement teams make the right choice.

- CNC machine tools (milling, turning, grinding)
- Packaging and labeling machinery
- Semiconductor and electronics assembly equipment
- Conveyor and material handling systems
- Printing and textile machinery
- Robotic arm joint control (auxiliary axes)
System Compatibility
- Compatible PLCs: Mitsubishi iQ-F (FX5U/FX5UC), iQ-R series via Motion CPU (e.g., R16MTCPU)
- Compatible HMIs: Mitsubishi GOT2000 series
- Compatible Servo Motors: HG-KN73J, HG-SN72J, HG-KN73BJ (750 W, 17-bit encoder)
- Programming Software: MR Configurator2 (SW1DNC-MRC2)
- Network: SSCNET III/H fiber optic — up to 16 axes per network
Selection Guide
Use the following criteria to confirm the MR-JE-70C is the right drive for your application:
- Step 1 — Power match: Confirm motor rated output is 750 W (0.75 kW). For 400 W → MR-JE-40C; for 1 kW → MR-JE-100C.
- Step 2 — Interface: Requires SSCNET III/H network controller. If using pulse-train input, select MR-JE-70A instead.
- Step 3 — Voltage: Confirm 200–240 V AC supply. For 400 V systems, the MR-JE series is not applicable — consider MR-J4 or MR-J5.
- Step 4 — Encoder: Verify motor uses 17-bit absolute encoder (HG-KN/SN series). Incompatible with older TS/HC motor encoders.
- Step 5 — Environment: IP20 rating — suitable for enclosed control panels. Not for open or wet environments.

Replacement & Compatibility FAQ
Q: Can I replace an MR-JE-70A with an MR-JE-70C?
A: Only if your controller supports SSCNET III/H. The MR-JE-70C does not accept pulse-train input.
Q: Is the MR-JE-70C compatible with older MR-J2S motors?
A: No. MR-JE series requires HG-KN/SN motors with 17-bit encoders. MR-J2S motors use incompatible encoder protocols.
Q: Can I use the MR-JE-70C as a standalone drive without a Mitsubishi PLC?
A: Limited functionality only. Speed/torque analog mode is available, but full positioning requires SSCNET III/H network control.
Q: What is the difference between MR-JE-70C and MR-J4-70B?
A: Both use SSCNET III/H, but the MR-J4-70B supports advanced vibration suppression, higher encoder resolution (22-bit), and more control modes. The MR-JE-70C is the cost-optimized entry-level option.
Q: Do you provide a warranty?
A: Yes — 30-day return guarantee. Extended warranty options available; contact us for details.
