The MR-J2S-700B servo amplifier was manufactured by Mitsubishi Electric. It belongs to the MELSERVO J2 super series of servo amplifiers designed for precise servo motor motion control in various industrial applications. The MR-J2S-700B servo amplifier has a rated power output of 7 kW, making it suitable for driving high-power servo motors. It utilizes the SSCNET bus control system, which is a high-speed serial communication network developed by Mitsubishi Electric for connecting servo amplifiers and other control devices. The MR-J2S-700B servo amplifier operates on a three-phase power supply, and its voltage rating is 200-230V AC. The heat dissipation area required for the servo amplifier is specified as 6 square meters, so that it can dissipate heat effectively during operation. Under typical rated torque conditions, the MR-J2S-700B servo amplifier generates approximately 300 W of heat. When the servo is turned off, the amount of heat generated is reduced to 25 W to ensure energy efficiency and minimize heat dissipation when the system is idle. The power supply capacity required for the MR-J2S-700B is in the range of 10-10.6 kVA. The load inertia moment ratio rating is 15 times, indicating the capability to handle systems with higher inertia loads. During power-up, the main circuit power supply experiences an inrush current rating of 88A, which is attenuated to approximately 20A within 20 ms. Similarly, the control circuit power supply has an inrush current rating of 30A, attenuated to approximately 0A in a few milliseconds. These features protect the MR-J2S-700B servo amplifier and connected devices from excessive current flow during startup. The MR-J2S-700B servo amplifier includes a built-in regenerative resistor with a power rating of 170 W. This resistor helps dissipate excess energy generated during deceleration or braking, improving energy efficiency and reducing stress on the system.
