MR-J3-350B

This Mitsubishi's servo drive MR-J3-350B is revolutionizing the field of automated industrial positioning with its streamlined configuration software. It boasts advanced capabilities, increased efficiency, and improved accuracy to optimize performance in various applications.

This ultra-portable model MR-J3-350B packs a punch with natural cooling to efficiently regulate high temperatures. The servo amplifier is designed for industrial strength power and is readily equipped with an advanced dynamic braking feature.

Technical Specifications of MR-J3-350B:

The model MR-J3-350B utilizes a resonance suppression filter that can be effectively adjusted to reduce the resonant frequencies of mechanical systems. Its gain, depth, and width parameters offer numerous possibilities for fine-tuning.

This MR-J3-350B model is designed to keep your system running safely and efficiently, with multiple safeguards like an overcurrent cutoff for preventing damage from current overloads, servo motor overheating protection for avoiding temperature-related issues, regenerative fault avoidance that allows the device to run smoothly without glitches caused by supply fluctuations or other external factors.

The model MR-J3-350B features three distinct control modes; position, speed and torque. Offering both positional accuracy and the highest speeds, these controls are switchable during operation - giving maximum flexibility to complete whatever task is needed.

By constantly assessing machine vibrations over a period of time, the servo amplifier's adaptive tuning function can modify its built-in filter properties according to changing conditions.

The model MR-J3-350B is equipped with a PWM and current control system, backed by an impressive 30W power supply that ensures performance despite frequency fluctuations up to 5%.

An advanced vibration suppression control filter reduces machine-side vibrations, such as workpiece end and base shaking. By attenuating the frequency indicated in positioning instructions, this model ensures a smooth operation of your machinery while maintaining precise results.

Operating and Installation Ambiance Conditions:

To ensure its safety, this MR-J3-350B model requires a robust control cabinet with an IP54 or higher rating. Keep generous spacing around the servo amplifier – 10 mm on both sides and 40 mm above/below for proper ventilation.

Professional installation is essential for optimal model performance and must be done by an electrically qualified professional. Beforehand, make sure the site where the servo amplifier will be used is free from all dust and hazardous materials that could corrode or cause injury to personnel.

This MR-J3-350B servo amplifier is designed to perform optimally within a temperature range of 0 - 55°C, even at up to 1000 m above sea level. For the most effective performance in challenging environments, it's best used between -20 and 65°C with a non-condensing relative humidity of 90%.

Additional Special Functions:

MR Configurator allows users to visualize and monitor machine motions by simulating the results of an analyzer on a personal computer screen. This feature provides important insight into recognizing potential problems before they occur.

As servo systems rely on ball screws or similar components, it is critical to consider the possible occurrence of high-frequency resonance. To ensure performance and reliability, it's important to be attentive to setting limited ranges for torque commands within a low-pass filter function provided by the drive system.

MR Configurator enables the model MR-J3-350B to efficiently find suitable gains that result in no overshoot. With this powerful capability, the gain adjustment process is greatly simplified and accelerated.
