The MITSUBISHI MR-J2S-350A is a 3.5kW servo drive from the renowned MR-J2S series, designed to deliver exceptional precision and reliability in industrial automation. This model features a sine-wave PWM control system with current control, providing smooth torque and speed regulation across a wide range of applications. With a maximum command input frequency of 10Mpps, the MR-J2S-350A excels in high-speed positioning tasks, making it ideal for CNC machinery, robotics, and packaging lines. Its main circuit accepts 3-phase 200 to 230VAC power, while the control circuit operates on 1-phase 200 to 230VAC, ensuring compatibility with standard industrial supplies. The drive includes comprehensive safety protections such as overcurrent, regeneration overvoltage, and encoder fault detection, plus a built-in dynamic brake for models in this power class. Operating within 0 to 55°C and up to 90% RH, the unit features fan cooling and an open IP00 structure, weighing approximately 2.0 kg (4.4 lb).
