It communicates over SSCNET III/H at selectable cycle times of 0.222 ms, 0.444 ms, or 0.888 ms, which sets the position-loop update rate for the motion bus. The built-in dynamic brake stops the motor shaft on a servo-off or fault condition without an external braking resistor for most inertial loads within the 1 kW rating. Functional safety is covered by STO (Safe Torque Off) per IEC/EN 61800-5-2, with a response time of 8 ms or less from STO input off to energy cutoff and a diagnostic coverage (DC) of 97.6% (medium). ## Panel integration & wiring IP20 open-frame construction means the amplifier is intended for enclosure mounting with cooling airflow. The main circuit draws 5.0 A rated input current; the control circuit pulls 0.2 A from the DC 24 V ±10% interface supply (0.3 A including the CN8 connector signal). Two analog monitor channels are available for outputting velocity, torque, or position signals to a scope or PLC analog input. The encoder interface uses Mitsubishi high-speed serial communication; encoder output pulses (ABZ phase) are available for external position feedback or master-slave gearing. Overseas compliance standards are listed per the manufacturer's conformity product page. The amplifier is designed for indoor use only, at altitudes up to 2000 m, in atmospheres free of corrosive gas, inflammable gas, oil mist, and dust. Vibration tolerance is 5.9 m/s² from 10 Hz to 55 Hz in X, Y, Z directions.","metaTitle":"Mitsubishi MR-J4-100B MELSERVO-J4 Servo Amplifier, 1 kW, 200","metaDescription":"Mitsubishi MR-J4-100B MELSERVO-J4 servo amplifier, 1 kW capacity, 200V class, SSCNET III/H, STO safety.
