The Mitsubishi Electric servo drive model MR-J4-350A-RJ is a single-axis servo amplifier belonging to the MELSERVO-J4 series, which is recognized for its high-performance AC servo solutions. This unit is rated for a nominal output of 3.5 kW and is designed to operate with a three-phase AC 200 V power supply. It features a universal interface, making it compatible with a wide range of control systems and applications.
A key special specification of this servo amplifier is its support for full closed-loop control via a 4-wire system, along with the capability to accept encoder ABZ phase signals directly from the device side. This configuration allows for precise position feedback and enhanced control accuracy. Additionally, the MR-J4-350A-RJ is equipped to support functional safety units and is fully compatible with positioning mode operations, meeting stringent safety and performance requirements in industrial automation.
As a universal interface type servo amplifier, it supports multiple control modes: position control via pulse train commands, as well as speed and torque control through analog voltage commands. It can handle a maximum command pulse frequency of up to 4 Mpulses/s, enabling high-speed and high-precision motion control. The amplifier is optimized to work with Mitsubishi rotary servo motors that feature high-resolution encoders and advanced processing capabilities, resulting in superior positioning accuracy and smoother rotational performance.
To simplify system tuning and maximize machine performance, the MR-J4-350A-RJ includes a one-touch adjustment function. This feature automatically configures servo gains while incorporating mechanical resonance filters, vibration suppression control II, and low-pass filters. The advanced vibration suppression function can be activated with minimal effort, allowing the system to fully leverage the mechanical capabilities of the connected machinery. Furthermore, the drive supports real-time automatic adjustment, which automatically sets the necessary responsiveness for optimized operation without requiring manual intervention.
