Executing high-precision closed-loop motion control, the Mitsubishi Electric MR-J2S-350A is a high-performance AC servo drive engineered for demanding industrial positioning applications. This 3.5 kW capacity drive operates within the renowned MELSERVO-J2S series, utilizing advanced sinusoidal PWM control with current loop integration to ensure exceptionally smooth motor rotation even at low speeds. Compatible with both three-phase 200V AC and single-phase 230V AC input configurations, this unit serves as a critical component in machine tool feed drives, automated packaging lines, and multi-axis Cartesian systems.
| Manufacturer | Mitsubishi Electric |
| Model | MR-J2S-350A |
| Series | MELSERVO-J2S |
| Control System | Sinusoidal PWM control / current control system |
| Rated Output Power | 3.5 kW |
| Input Voltage / Phase | 3-phase 200-230V AC, 50/60 Hz OR Single-phase 230V AC, 50/60 Hz |
| Permissible Frequency Fluctuation | Within +/- 5% |
| Speed Frequency Response | 550 Hz or more |
| Dynamic Brake | Built-in |
| Cooling Method | Forced ventilation (built-in cooling fan) |
| Operating Ambient Temperature | 0 to 55 degC (non-freezing) |
| Ambient Humidity | 90% RH or less (non-condensing) |
| Country of Origin | Japan |
| Shipping Weight (Calculated) | 3.5 kg |
| Package Dimensions (Calculated) | 280 x 200 x 130 mm |
| Terminal / Port | Function / Circuit Assignment |
|---|---|
| L1, L2, L3 | Main circuit power input (3-phase AC) |
| L11, L21 | Control circuit power input |
| U, V, W | Servo motor output terminals (Phase matching is critical) |
| P, Cr | External regenerative resistor connections (Remove jumper across P-D if used) |
| CN1A / CN1B | I/O signal connector ports for host controller interfacing |
| CN2 | Encoder feedback connector port |
The MELSERVO-J2S series is a legacy standard. When migrating legacy systems to newer architectures (such as the MR-J4 or MR-J5 series), dynamic parameter conversion and specialized terminal adapter modules are required. Ensure any replaced units match the correct physical suffix (e.g., "-A" for general-purpose analog/pulse train, or "-B" for SSCNET bus networks) as their control boards are completely non-interchangeable.
Under heavy, high-inertia duty cycles, the MR-J2S-350A is prone to AL-30 (Regenerative Error) or AL-32 (Overvoltage) faults. If these faults persist during rapid deceleration ramps, the built-in regenerative capacity has been exceeded. Resolving this requires installation of an external, high-wattage regenerative resistor across terminals P and C, with the factory jumper between P and D removed in the software parameters.
Always route high-voltage motor output cables (U, V, W) in separate conduits away from sensitive low-voltage I/O cables (CN1A/CN1B) and encoder lines (CN2). Unshielded parallel routing is a primary cause of position deviation errors and signal noise. Ensure control circuit power (L11, L21) is energized prior to or simultaneously with main power (L1, L2, L3) to allow the control CPU to initialize phase-loss diagnostics correctly.
