TECHNICAL SPECIFICATIONS

MR-J2-350A

The Mitsubishi AC servo drive module MR-J2-350A is an advanced technological solution for industrial-scale motor control, with a 3-phase voltage supply of 200 - 230 VAC and input frequency between 50 - 60 hertz. This finely tuned device weighs just 2 kilograms, streamlining its efficient usage in modern applications.

This sophisticated servo drive is designed to provide optimal motion control capabilities for systems ranging from 1 to 32 axes. These drives respond quickly and accurately with a 250 Hz speed response rate by utilizing sine-wave PWM signals.

Technical Specifications of MR-J2-350A:

This robust model MR-J2-350A offers a fresh solution for AC power systems that simplifies system setup and requires no programming. It enables voltage swings between 170 - 253 VAC and +/- 5% accuracy in frequency fluctuation, providing an efficient yet powerful alternative approach to positioning technology.

The model MR-J2-350A provides an array of safeguards to ensure peak performance, including overcurrent cutoff, servo motor heat protection, regenerative fault prevention, under-voltage avoidance, overspeed monitoring, and extensive error guard.

With an adjustable speed control range of 1:1000 - 1:5000, this model MR-J2-350A allows the user to precisely control its internal and analog speed commands. The analog command input has a convenient 0 - +/- 10V span that enables fine-tuning for higher accuracy in regulating movement velocity.

The model’s position control allows pulse frequencies of up to 400 kpps for the differential receiver and 200 kpps for open collector output, maximizing functionality.

The servo motor can be swiftly halted in emergencies due to the dynamic brake instantaneously activated by its amplifier. The MR-J2-350A model’s position control offers an adjustable range from 0 - 10,000 pulses for precise positioning accuracy.

Operating and Installation Ambiance Conditions:

To ensure optimal safety, a vertical installation in an IP54-rated control cabinet is necessary for the servo amplifier to function adequately. Furthermore, be sure to provide 100 mm of clearance between each unit and the interior of the recommended cabinet.

To avoid overheating, you must employ a fan to maintain the temperature within your control cabinet’s box at or below ambient levels when several servo amplifiers are installed. Furthermore, before proceeding, you must flush any dirt and dust near the installation with air.

This module MR-J2-350A operates best in moderated settings with a relative humidity of 90%, temperatures between -20 and +65 Celsius, and altitudes up to 1,000 meters. Its efficiency is maximized when operating within the 0 - 55 degrees Celsius temperature range.

To ensure maximum performance and minimal vibration, install the model MR-J2-350A in a clean space with no foreign substances. It is essential to have an experienced technician operate and install it for optimal results.

Operational Warnings and Cautions

To ensure reliable operation, the current must not exceed 80 mA when external relays are used. If interface consumption exceeds this limit, an additional power source is crucial for the safe functioning of the system. Additionally, SG connectivity to an emergency stop signal before operations is mandatory.

Don’t forget to ensure the diode is pointing in the right direction. If wired incorrectly, the servo amplifier MR-J2-350A won’t send any signals, and safety features will be disabled. Always connect your servo amplifier’s protective earth connector to its control box counterpart to prevent dangerous electrical shocks.
