The servo amplifier offers simple wiring by having connectors on the top and bottom surfaces, and allows all cables and wires to be routed through wiring ducts. LEDs and switches are located on the front surface of the servo amplifiers for easy operation.

Use the tuning methods that are optimal for your machines.

This function detects changes in mechanical parts (ball screw, guide, bearing, belt, etc.) by analyzing changes in machine friction, load moment of inertia, unbalanced torque, and vibration components from the data inside a servo amplifier, supporting timely maintenance of these parts.

This function displays the cumulative energization time and the number of inrush relay on/off times. The data can be used to check life of the parts as a rough guide.

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 servo amplifiers detect an open phase condition on the output side. The alarm can be distinguished from other alarms such as the overload alarm, reducing the time required to restore the system.

The encoder communication diagnosis checks the encoder communication circuit in the servo amplifier. This function is useful for classifying the cause of errors (such as disconnected encoder cables) when the encoder communication alarm occurs.

This function reduces a position deviation to nearly zero not only during constant-velocity operation, but also during constant acceleration/deceleration.

This function suppresses quadrant protrusion caused by friction and torsion generated when the servo motor rotates in a reverse direction.

This function reduces path errors which occur when the servo motor reciprocates.

The servo amplifiers drive the servo motors by receiving commands (position/velocity/torque) at regular intervals in synchronous communication with the CC-Link IE TSN-compatible controller.

Configure an EtherCAT® system with the high-performance MR-JET series servo amplifiers.

The HG-KNS/HG-SNS servo motors are equipped with a 22-bit absolute/incremental encoder and enable high-accuracy positioning and smooth rotation.^*1
The HG-KNS/HG-SNS servo motors are fully compatible with the prior series as they have the same dimensions and use the same encoder and power cables.

Use the battery to configure an absolute position detection system.
MR-BAT6V1 is built in MR-BAT6V1SET-B.
