MR-J4-A-RJ Servo Amplifier Built-in Positioning Function Manual

This document describes the MR-J4-A-RJ servo amplifier series from MELSERVO-J4, which features a built-in positioning function that eliminates the need for command pulses or an external positioning module. It details three positioning methods (point table, program-based, and indexer/turret), along with extended functions like simple cam, encoder following, mark sensor compensation, and MODBUS RTU communication for enhanced system flexibility and ease of use.
