Designed to meet the stringent demands of high-speed, multi-axis motion control applications, the Mitsubishi Electric MR-J4-40B is a highly responsive 200V servo amplifier operating on the proprietary SSCNET III/H fiber optic communication network. This unit provides a rated output of 0.4 kW (400W) and leverages advanced real-time tuning algorithms to minimize mechanical vibration and maximize positioning accuracy. Built with native Safe Torque Off (STO) functionality, the hardware ensures high-integrity functional safety within modern industrial architectures while maintaining a compact IP20 physical footprint.
| Parameter | Specification |
|---|---|

| Model Number | MR-J4-40B |
| Voltage Class | 200V Class |

| Output Rated Current | 2.8 A |
| Main Circuit Power Input | 3-phase or 1-phase AC 200 V to 240 V, 50 Hz / 60 Hz (Rated: 2.6 A) |
| Control Circuit Power Input | 1-phase AC 200 V to 240 V, 50 Hz / 60 Hz (Rated: 0.2 A, 30 W) |
| Control Method | Sinusoidal PWM control, current control system |
| Built-in Regenerative Resistor | 10 W |

| Operating Ambient Temperature | 0 degC to 55 degC (non-freezing) |
| Protection Rating | IP20 (Self-cooling, open type) |
| Shipping Weight (Calculated) | 2.0 kg |
| Package Dimensions (Calculated) | 210 mm x 180 mm x 95 mm |
| Connector / Terminal | Functional Assignment |
|---|---|
| CN1A | SSCNET III/H Optical Cable Input (from controller or previous axis) |
| CN1B | SSCNET III/H Optical Cable Output (to subsequent axis or end termination) |
| CN2 | Motor Encoder Interface (high-speed serial feedback) |
| CN3 | Analog Monitor Output & I/O Signal Terminal |
| CN8 | Safe Torque Off (STO) Safety Signal Input Terminal |
The unit includes a built-in J3 compatibility mode, enabling seamless retrofitting of older MR-J3-40B architectures without replacing existing servo motor physical runs. However, note that parameters must be migrated via MR Configurator2, and maximum bus speed will match the lower J3 performance characteristics unless the upstream controller is fully reconfigured to the SSCNET III/H native protocol.
When operating on a single-phase AC 200V line instead of a three-phase line, the power supply must be wired to L1 and L3 terminals (leaving L2 empty). Under single-phase configurations, the thermal dissipation characteristics within the electrical enclosure change significantly. Panel builders must ensure an active airflow buffer of at least 10 mm on both sides of the amplifier when mounting multiple units in a daisy-chain configuration.
The fiber-optic SSCNET III/H cables (MR-J3BUS) must never be bent past their minimum specified bend radius of 25 mm. Exceeding this limit will result in intermittent optical communication errors (such as AL.37 or AL.E6). Always use the dedicated CN8 shorting connector if the STO function is not integrated into an active safety PLC loop, or the amplifier will remain in a permanent STO block state.
Mount the amplifier vertically on a flat, grounded metallic backplate to ensure proper convective self-cooling behavior.
Connect the protective earth (PE) terminal first, utilizing a dedicated, heavy-gauge copper conductor to mitigate high-frequency EMI.
Route main AC power lines (L1, L2, L3) and control power lines (L11, L21) through a dedicated noise filter and circuit protection group.
Insert the optical network connections into CN1A and CN1B, ensuring they securely click into place with dust covers removed.
