The MR-J4-20B is a Servo Amplifier from Mitsubishi Electric for AC Servo Motors. It was designed from the ground up to provide precise and effective motor control in various automation settings. The MR-J4-20B's ability to operate reliably is ensured by its power supply voltage range of 200–230 volts AC and its output power capacity of 200 Watts. The MR-J4-20B gives users a choice between controlling the current or the speed, providing them the flexibility to meet the requirements of various applications. Its multi-mode capabilities, which include position, speed, and torque control modes, further increase its adaptability, making it suitable for a wide variety of automation applications. The MR-J4-20B includes an encoder to provide feedback to the motor, and this encoder can either be incremental or absolute. This enables precise monitoring of the current state of the motor in real-time. In addition, this servo amplifier uses Mitsubishi's unique SSCNET III/H network, making communication more efficient and dependable. Built-in protection functions protect the MR-J4-20B from hazards such as overcurrent, overspeed, overvoltage, overload, and abrupt power loss. Safety was a primary consideration during the development of this product. Therefore, it can use additional safeguards to protect the device from dangers like overcurrent, overvoltage, undervoltage, overload, and overheating. In addition to this, the amplifier can efficiently manage several digital outputs, significantly improving its control capabilities. The MR-J4-20B is a compact and sturdy solution with a weight of 0.8 kilos and an operating temperature range that goes from 0 degrees Celsius to 55 degrees Celsius.
