The model MR-J2S-350B from the J2S series of servo amplifiers manufactured by Mitsubishi offers efficient and effective motion control for various applications. This reliable, general-purpose model is easy to use and provides great results.

When the power regeneration does not meet requirements, this model MR-J2S-350B seamlessly transitions to its return converter. It utilizes a three-phase power supply ranging from 200 – 230 VAC voltages to adjust adaptively for maximum efficiency and performance.

Technical Specifications of MR-J2S-350B:

The regenerative option in the model MR-J2S-350B boosts the existing power supply. Providing up to 131072 readings each revolution, this precise servo amplifier weighs only 2 kg while maintaining its high-resolution encoder technology for reliable results.

Utilizing the MR Configurator software, this MR-J2S-350B model can make gain modifications without exceeding the desired parameters. Its efficient and adaptive search method is unparalleled in its range of capabilities.

To protect the power transistor in the main circuit from potential damage caused by sudden speed changes or excessive load, the servo amplifier MR-J2S-350B is fitted with a torque limit control that can be adjusted via an external analog voltage input or onboard parameter setting.

The model MR-J2S-350B is designed to avert disaster in various emergency conditions, from excessive current and voltage during regeneration, overloads, or encoder errors to unexpected power loss or overspeeding. It provides the utmost protection for your system against these potentially damaging cases.

This model MR-J2S-350B utilizes an adaptive vibration suppression mechanism to proactively respond and adjust the filter settings based on mechanical vibrations. This ensures consistent levels of performance in changing environmental conditions.

The MR-J2S-350B model features a combination of dynamic braking and current-regulating systems, plus an auto-tuning feature that intelligently reviews the load on the motor shaft to automatically adjust the gain for optimal performance.

Ambiance Conditions (operating and Installation):

The model MR-J2S-350B can withstand temperatures up to +55 degrees Celsius and heights as high as 1,000 meters. To ensure optimal safety and performance in any environment, the deployment requires an experienced operator familiar with advanced installation procedures.

The servo amplifier MR-J2S-350B is engineered to operate tolerably in a dry, indoor environment. Considering the relative humidity, it should not exceed 90%, and temperatures must remain between -20°C and +65°C for optimal performance. The places of utilization need to be free from flammable gases or any other airborne debris that could compromise safety standards.

The control cabinet that houses the model requires an efficient protection rating of IP54. To ensure peak performance and optimum stability, a fan with a 10.16-inch diameter should be placed vertically directly above the servo amplifier for optimal cooling operations.

Regulatory Safety Measures:

In the unfortunate servo amplifier MR-J2S-350B malfunction, a combination of dangerously high current and exposed charging terminals can create an unsafe situation in which fire or electric shock are both possible risks. To prevent such complications, users must ensure the front cover remains intact before operating this equipment.

To maximize any servo motor's performance, pairing it with a corresponding servo amplifier is essential. For safety reasons, always wire up the power supply for the servo amp so that the main circuit power can be easily disconnected using its L1-L3 outputs and magnetic contactor.
