Why Engineers Specify This Model
- Compact 45 mm Width — Slim profile reduces control-cabinet footprint without sacrificing power density at 750 W.
- CC-Link IE Field Basic — Standard Ethernet wiring eliminates proprietary cabling; enables seamless integration with Mitsubishi iQ-R, iQ-F, and third-party controllers.
- 22-Bit Encoder Resolution — Over 4 million counts per revolution delivers exceptional positioning accuracy for precision machining and assembly tasks.
- One-Touch Tuning — Adaptive auto-tuning minimises commissioning time and compensates for load inertia changes during operation.
- Built-in Safety — STO (Safe Torque Off) function meets IEC 61800-5-2 SIL 2 / PLd requirements without external safety relays.
- Vibration Suppression — Advanced filter algorithms suppress mechanical resonance up to 4,500 Hz, extending machine service life.

Application-Specific FAQ
Q: Is the MR-JE-70C compatible with Mitsubishi iQ-F (FX5) PLCs?
A: Yes. Via CC-Link IE Field Basic over standard Ethernet, the MR-JE-70C integrates natively with the FX5U/FX5UC and iQ-R series without additional communication modules.
Q: Can this amplifier drive a motor larger than 750 W?
A: No. The MR-JE-70C is rated for matched 750 W servo motors only. For higher power requirements, consider the MR-JE-100C (1 kW) or MR-JE-200C (2 kW).
Q: What is the difference between MR-JE-C and MR-JE-A series?
A: The “-C” suffix denotes CC-Link IE Field Basic (Ethernet) command interface; the “-A” suffix uses pulse-train (analog/pulse) input. Specify based on your controller’s output type.
Q: Does the unit include a regenerative resistor?
A: The MR-JE-70C has a built-in regenerative circuit but does not include an external resistor. For applications with frequent deceleration or vertical axes, add an MR-RB series resistor.
Q: What warranty and after-sales support is available?
A: Konmask.com provides a standard inspection warranty. For OEM warranty claims, Mitsubishi Electric regional service centres handle repairs. Contact us for RMA procedures.
