Tuning Functions
Use the tuning methods that are optimal for your machines.
Quick Tuning
One-Touch Tuning
This function automatically completes servo gain adjustment according to the mechanical characteristics and reduces the settling time just by turning on the one-touch tuning. The servo gain adjustment includes the machine resonance suppression filter, advanced vibration suppression control II, and the robust filter. Controlling overshoot and vibration is improved, maximizing your machine performance.
Advanced Vibration Suppression Control Ⅱ
This function suppresses two types of low frequency vibrations, owing to vibration suppression algorithm which supports three-inertia system. This function is effective in suppressing residual vibration with relatively low frequency of approximately 100 Hz or less generated at the end of an arm and in a machine, enabling a shorter settling time. Adjustment is easily performed on MR Configurator2.
Command Notch Filter
The frequency can be set close to the machine vibration frequency because the command notch filter has an applicable frequency range between approximately 1 Hz and 2000 Hz.
Machine Resonance Suppression Filter
The expanded applicable frequency range is between 10 Hz and 8000 Hz. Five filters are simultaneously applicable, improving vibration suppression performance of a machine. The machine resonance frequency is detected by the machine analyzer function in MR Configurator2.
Reduced Energy and Maximized Space with Simplified Wiring (200 V Class)
Simple Converter MR-CM
Utilizing a common bus connection conserves energy through the efficient use of regenerative power. Wiring can be simplified and installation space can be saved by reducing the number of molded-case circuit breakers and magnetic contactors. The MR-CM simple converter can connect to up to six compatible servo amplifiers having a total capacity of 3 kW or lower.
Wiring for the bus and the control circuit power supply can be simplified by using daisy chain power connectors for passing wiring.
- * Simple converters are also available with MR-J5-A.
Multi-Axis Servo Amplifiers J5W2-GJ5W3-G
400 V class Compact 3.5 kW Servo Amplifiers
400 V Class Drive Unit (Converter Separate Type) MR-J5D-G4
- MR-J5D-G4 drive units (converter separate type) are newly added to the product lines of the 400 V class servo amplifiers and are available in 1-axis/2-axis/3-axis types.
- Combined with an MR-CV_4 power regeneration converter unit, MR-J5D-G4 can create an energy-saving, space-saving, and less-wiring servo system.
- MR-J5D-G4 supports safety communication of CC-Link IE TSN, enabling functional safety without a dedicated unit. For multiple-axis servo systems, functional safety can be used just by using a network cable.
Features of MR-J5D-G4 Drive Units
- The common DC bus connection saves energy and space, and reduces wiring.
- MR-J5D2-G4 (2-axis drive unit)/MR-J5D3-G4 (3-axis drive unit) save space and reduce wiring further.
- MR-J5D1-G4/MR-J5D2-G4/MR-J5D3-G4 support safety sub-functions as standard. For multi-axis drive units, the safety sub-functions such as STO can be set for each axis even through the safety communication of CC-Link IE TSN.
- The drive units are equipped with a replaceable cooling fan unit, which can be easily replaced by users.
Further Energy-Saving with Common DC Bus Connection and Power Regeneration System J5D-G4
When multiple MR-J5D-G4 drive units are connected to an MR-CV_4 power regeneration converter unit by a common DC bus connection, the regenerative power of one axis can be used for driving other axes, contributing to energy-saving.
The MR-CV_4 power regeneration converter unit has a power regeneration system which returns the regenerative power back to the power supply, enabling the regenerative energy to be used for other systems for further energy-saving. In addition, when the converter unit is used, a regenerative option is not required, resulting in reduction of heat generation.
400 V Servo Amplifiers Providing New Combinations with Servo Motors
The MR-J5 series 400 V class servo amplifiers can drive 50 W to 7 kW servo motors. The HK-KT series, HK-ST series, and HK-RT series are available, which will optimize your machines.

Drive Recorder
This function continuously monitors the servo status and records the status transition such as a trigger condition before and after an alarm for a fixed period of time. Reading the servo data on MR Configurator2 helps you analyze the cause of the alarm. In addition to the monitor values and the waveform of the past 16-time alarms in the alarm history, the system configuration and the servo parameters are displayed. Alarm occurrence time is also displayed when the servo amplifier and the controller are normally in communication on CC-Link IE TSN.
The data can be outputted to a GX LogViewer format file.
Connection/Communication Diagnosis
Disconnection Detection
Servo Motor Incorrect Wiring Detection J5W2-GJ5W3-G
Super Trace Control
This function reduces a position deviation to nearly zero not only during constant-velocity operation, but also during constant acceleration/deceleration.
The path accuracy will be improved in high-rigidity machines.
Lost Motion Compensation
This function suppresses quadrant protrusion caused by friction and torsion generated when the servo motor rotates in a reverse direction.
Therefore, the accuracy of circular path will be improved in path control used in XY table, etc.
Path Tracking Model Adaptive Control
This function reduces path errors which occur when the servo motor reciprocates. Normally, when positioning control is executed, the model adaptive control adjusts the control to shorten a settling time. Instead, this function reduces overshooting to improve path accuracy, which is suitable for machines that require high-accuracy path control such as processing machines.
