Command Interface

CC-Link IE TSN

The servo amplifiers receive commands (position/velocity/torque) from a CC-Link TSN-compatible controller at regular intervals through synchronous communication and drive the servo motors.
When combined with a Motion module or Motion Control Software, the servo amplifiers perform exact synchronous operation of axes and machines through high-speed, high-precision time synchronization.
The servo amplifiers support CiA^® 402 drive profile and enable the profile mode (position/velocity/torque) and the positioning mode (point table).
When combined with the controllers supporting the profile mode, the servo amplifiers generate a positioning command to a target position, reducing loads of the controllers.

• *1The communication cycle of ≥ 31.25 μs is applicable when MR-J5-G/MR-J5D1-G4 are combined with RD78GH.

SSCNET III/H

Replacement of the servo amplifiers in the existing system with MR-J5-B/MR-J5W2-B/MR-J5W3-B is possible, which enables the MELSERVO-J5 series servo system to be configured with the use of the existing programs of the servo system controller.
The parameter conversion function of the engineering software and "Transition from MELSERVO-J4 Series to J5 Series Handbook" are available to support the replacement.

CC-Link IE Field Network Basic

CC-Link IE Field Network Basic-compatible master stations such as an FX5U CPU module can control MR-J5-G/MR-J5D1-G4 servo amplifiers. The servo amplifier can be operated as a CANopen device via a link device.
The profile mode (position/velocity/torque) and the positioning mode (point table) are supported.
MR-J5-G servo amplifiers can be connected to existing systems using MR-J4-GF.
In addition, MR-J5-G/MR-J5D1-G4 newly supports the line topology. ^*1

• *1When a device which does not support the line topology is used, the line/star mixed topology is applicable.

General-Purpose Interface

General-purpose interface-compatible MR-J5-A servo amplifiers support pulse trains and analog input. The control mode can be switched between position/speed/torque control modes. When an open collector is used, both sink and source inputs are enabled.

EtherCAT^®

EtherCAT^®-compatible servo amplifiers are available, enabling higher-performance MR-J5 servo amplifiers with enhanced functions on the EtherCAT^® system.
The servo amplifiers^*2 support the touch probe. (Latch accuracy: 1 μs)

Seamless Connectivity Between TCP/IP Devices and a Servo System

TCP/IP communication (information communication) can be mixed in the same line with the real-time control communications of CC-Link IE TSN.
CC-Link IE TSN device stations and TCP/IP devices can be connected on the same network, achieving a flexible and integrated network system.
Note that the TCP/IP devices must be connected after servo amplifiers and I/O modules.
