Mitsubishi MR-J4-40A is a MELSERVO MR-J4 series AC servo amplifier used in compact machine automation, small motion control systems, positioning equipment, and factory maintenance replacement projects. It is designed for lower-capacity servo applications where accurate movement, stable speed control, and compact installation are required.
This model is commonly used in small machine axes, feeding systems, labeling equipment, compact packaging machines, and automatic positioning devices. Although it is a smaller capacity servo amplifier, MR-J4-40A is still important for maintenance because a failed drive can stop a key machine axis and affect production output.
| Model | MR-J4-40A |
| Brand | Mitsubishi |
| Series | MELSERVO MR-J4 |
| Product Type | AC Servo Amplifier / Servo Drive |
| Capacity Class | 400 W class, confirm by nameplate and motor combination |
| Interface Type | A-type general-purpose interface, confirm by installed machine |
| Application | Compact Machine Automation and Servo Motion Control |
| Replacement Check | Confirm servo motor, cable connection, control mode, power supply, and parameter file |
MR-J4-40A is used in compact servo-driven machines, small positioning systems, labeling machines, feeding equipment, light-duty conveyors, packaging equipment, indexing mechanisms, and automatic assembly fixtures. It should be matched with the correct Mitsubishi servo motor, encoder cable, power cable, and control system.
Before replacing MR-J4-40A, confirm the complete model number, drive rating, motor model, encoder feedback, input power, cable condition, servo parameters, and alarm code. Small servo drive faults may also be caused by motor overload, encoder cable damage, brake problems, poor wiring, mechanical resistance, or incorrect parameter settings.
Related models include MR-J4-40A, MR-J4-40B, MR-J4-70A, MR-J4-100A, MR-J4-200A, MR-J2S-40A, and MR-J3-40A. These models may differ by generation, capacity, interface type, compatible motor, and application requirement.
DF Automatic supplies Mitsubishi MR-J4 servo amplifiers, MR-J3 and MR-J2S servo drives, MELSERVO servo motors, encoder cables, power cables, PLC modules, HMI panels, and industrial automation spare parts for factory maintenance, equipment repair, and compact machine automation.
