Mitsubishi MR-J2S-70A Servo Amplifier 750W MELSERVO-J2-Super

Mitsubishi MR-J2S-70A adalah AC servo amplifier dari seri MELSERVO-J2-Super dengan kapasitas 750 W atau 0,75 kW, yang dirancang untuk aplikasi motion control, positioning, speed control, dan torque control pada sistem otomasi industri. Servo amplifier ini menggunakan catu daya utama kelas 200–230 VAC dan dapat menggunakan suplai 3-phase 200–230 VAC maupun 1-phase 230 VAC sesuai konfigurasi. MR-J2S-70A menggunakan metode kontrol sine-wave PWM/current control untuk menghasilkan pengendalian motor servo yang presisi dan responsif.

MR-J2S-70A memiliki rated output voltage 3-phase 170 VAC dan output rated current hingga 5,1 A, dengan rentang frekuensi output 0–360 Hz. Servo amplifier ini dilengkapi dynamic brake built-in dan berbagai fungsi proteksi, termasuk overcurrent shutdown, regeneration overvoltage shutdown, overload shutdown melalui electronic thermal, proteksi overheating motor servo, encoder fault, regeneration fault, undervoltage, sudden power outage, overspeed, dan excess error. Sistem feedback mendukung encoder resolusi tinggi hingga 131.072 pulses/revolution pada konfigurasi motor/encoder yang sesuai.

Untuk kebutuhan commissioning dan maintenance, Mitsubishi MR-J2S-70A mendukung komunikasi dengan PC untuk parameter setting dan diagnosis serta memiliki fungsi servo seperti real-time auto tuning dan adaptive vibration suppression. Servo amplifier ini menggunakan konstruksi open type IP00 dengan pendinginan natural/self-cooling dan dirancang untuk pemasangan di dalam control panel. MR-J2S-70A cocok untuk mesin positioning, mesin packaging, assembly machine, conveyor, material handling, CNC dan berbagai sistem otomatisasi yang menggunakan servo motor Mitsubishi MELSERVO-J2-Super. Seri MR-J2S merupakan generasi lama dan model MR-J2S-70A saat ini umumnya digunakan sebagai spare part atau untuk maintenance sistem existing.
