Engineered for precise speed, torque, and position control in heavy industrial environments, the Mitsubishi Electric MR-J3-500A4 is a high-performance digital servo amplifier belonging to the MELSERVO MR-J3 product family. This unit operates on a 400V class grid and is optimized for managing brushless servo motors with continuous current requirements of up to 14.0 A. Incorporating advanced real-time auto-tuning and vibration suppression filters, this amplifier ensures high response levels while suppressing mechanical resonance on critical axes.

| Rated Output Voltage | 3-phase 323 VAC |
| Rated Output Current | 14.0 A |
| Dynamic Brake | Built-in |
| Cooling System | Force-cooling (integrated cooling fan) |
| Net Weight | 4.6 kg |
| Shipping Weight (Calculated) | 6.0 kg |
| Terminal / Connector | Function / Circuit Assignment |
|---|---|
| L1, L2, L3 | Main circuit 3-phase AC power input |
| L11, L21 | Control circuit 1-phase AC power input |
| U, V, W | Servo motor power output terminals |
| CN1 | General-purpose analog / pulse train I/O interface |
| CN2 | High-resolution encoder feedback input |
| CN3 | PC connection or parameter setup unit interface |
The MR-J3-500A4 is the general-purpose, non-networked analog/pulse-train variant within the MR-J3 400V series. Please note that it cannot directly replace the MR-J3-500B4, which is built exclusively for the SSCNET III optical fiber network. Ensure controller-side interface compatibility before deployment.
Due to the high thermal dissipation profile under continuous heavy load conditions, cabinet designers must ensure a minimum of 40 mm vertical clearing space above and below the amplifier. If installing multiple amplifiers adjacently in an enclosed panel, maintain an ambient operating temperature below 55 degC to prevent premature overtemperature trips.
To prevent high-frequency electro-magnetic interference (EMI) originating from the PWM inverter output, ensure the motor feed cables are properly shielded and grounded to the common baseplate. Additionally, control line cabling on the CN1 connector must use shielded, twisted-pair lines separated from the primary high-power wiring.
Before beginning installation, service, or wiring procedures, isolate and de-energize all primary input and control voltages. Wait a minimum of 15 minutes to allow internal high-voltage DC bus capacitors to discharge to a safe level. Verify with a calibrated multimeter that DC bus voltage is zero before making physical terminal contacts.
