Mitsubishi MR-J4-70B Servo Amplifier 0.75kW MELSERVO-J4 SSCNET III/H

Mitsubishi MR-J4-70B adalah servo amplifier dari seri MELSERVO-J4 dengan kapasitas 0.75 kW yang dirancang untuk sistem motion control berkecepatan tinggi dan presisi. Servo amplifier ini menggunakan interface komunikasi SSCNET III/H dan kompatibel dengan sistem servo Mitsubishi Electric untuk aplikasi mesin industri yang membutuhkan respons cepat, positioning akurat, serta kontrol gerakan yang stabil. MR-J4-70B menggunakan catu daya utama 200–240 VAC dan dapat digunakan dengan input 3-phase maupun 1-phase sesuai konfigurasi sistem.

MR-J4-70B memiliki rated output voltage 3-phase 170 VAC dengan rated current 5.8 A. Teknologi kontrol menggunakan sine-wave PWM control/current control, sedangkan komunikasi SSCNET III/H menawarkan komunikasi berkecepatan tinggi untuk integrasi servo system. Mitsubishi Electric juga membekali amplifier ini dengan berbagai fungsi servo seperti advanced vibration suppression control II, adaptive filter, robust filter, auto tuning, one-touch tuning, drive recorder, machine diagnosis dan fungsi perlindungan terhadap overcurrent, regenerative overvoltage, overload, encoder error, overspeed serta undervoltage.

Untuk kebutuhan keselamatan mesin, Mitsubishi MR-J4-70B memiliki fungsi STO (Safe Torque Off) sesuai IEC/EN 61800-5-2 dengan performa keselamatan hingga Category 3 PL e, SIL 3 dan SIL CL 3 sesuai konfigurasi dan kondisi implementasi sistem. Servo amplifier ini menggunakan forced cooling dengan enclosure open type IP20, memiliki rentang temperatur operasi 0–55°C, dan berat sekitar 1.4 kg. MR-J4-70B cocok digunakan pada mesin otomatisasi, positioning system, mesin packaging, semiconductor equipment, conveyor, robotics dan berbagai aplikasi motion control industri yang membutuhkan servo amplifier Mitsubishi dengan komunikasi SSCNET III/H.
