How to Use (General Setup Guide)

1. Mounting & Power

   • Securely mount the amplifier in a well-ventilated control cabinet (IP20 rating).

   • Connect the correct power supply (as per model specification). Confirm voltage compatibility and grounding.

2. Motor & Wiring

   • Wire the servo motor via the encoder, power, and brake terminals (if applicable).

   • Ensure proper earthing and correct orientation to prevent faults ManualsLib+1.

3. Signal Configuration & Connections

   • For MR‑JE‑70A: Use USB or RS‑422/RS‑485 for PC or controller interface.

   • For MR‑J2S‑70A: Use differential or open-collector pulse inputs for command signals.

   • Configure I/O signals and analog inputs per documentation ManualsLib+1mitsubishielink.com.

4. Parameter Setup & Tuning

   • One‑touch or auto‑tuning: Ideal for first-time configuration—automatically sets optimal gain parameters ManualsLib+1.

   • Manual tuning: Available when fine-tuning is needed. Use filters and parameter adjustments to refine performance ManualsLibMitsubishi Electric.

5. Operation & Monitoring

   • Use LED displays and control buttons on MR‑JE series for diagnostics and parameter inspection ManualsLib.

   • Monitor via software tools like MR Configurator2 (for MR‑JE) for real-time diagnostics and configuration.

6. Safety & Protection

   • Enable and test all protection mechanisms: overcurrent, regenerative faults, encoder errors, thermal warnings, and overspeed shutdowns.

   • Ensure proper EMI suppression and adherence to safety directives.
