Servo Amplifier
MITSUBISHI Servo Amplifier MR-J2-Jr Series
Simplifi ed Operation with Advanced Capabilities
• AC Servo that operates from a direct current power source: 21.6 – 30 VDC, 7 amps max.
• Analog speed control, analog torque control, pulse train position control, SSCNET high-speed
serial network, and built-in motion control – Multiple methods of control
• Patented Real-Time Adaptive Tuning – No adjustments required
• One amplifi er size for three motor sizes – Less stock
• RS-232 and RS-422 communication, compatible with Mitsubishi’s MR-Confi gurator Windows®- based software – Easy set up
• Multi-drop operation up to 32 axes with RS-422 – Simple monitoring
• One cable from motor to amplifi er – Neat
• UL, cUL, TUV, CE rated – Global acceptance
