The MITSUBISHI MELSERVO-J4 SERVO AMPLIFIER WITH DRIVE 200W MR-J4W3-222B is a high-integration multi-axis servo amplifier designed for demanding industrial automation applications. This unit operates with a main circuit power supply of 3-phase 170V AC (permissible range: 170V AC to 264V AC, 50/60 Hz) and a control circuit supply of 1-phase 200V AC to 240V AC (permissible range: 170V AC to 264V AC). It delivers a rated current of 2.8A per axis, with a total power supply capacity that supports efficient operation. The amplifier features sine-wave PWM control and current control for precise torque and speed regulation. Built-in regenerative resistance (100W) and a capacitor-based regeneration system (with a permissible charging moment of inertia of 6.08 × 10⁻⁴ kg·m²) ensure energy recovery and thermal stability. The SSCNET III/H communication interface offers command cycles of 0.222 ms, 0.444 ms, or 0.888 ms, enabling high-speed synchronous motion. Protective functions include overcurrent shut-off, regenerative overvoltage shut-off, overload shut-off (electronic thermal), servo motor overheat protection, encoder error protection, undervoltage protection, instantaneous power failure protection, overspeed protection, and error excessive protection. The amplifier is not compatible with encoder output pulses, fully closed loop control, or scale measurement functions, making it ideal for standard servo applications requiring high reliability and compact design.
