High-PrecisionTuning
Servo gain adjustment with one-touch ease
Advanced One-Touch Tuning Function

Servo gain adjustment is complete just by turning on the one-touch tuning function. With this function, machine resonance suppression filter, advanced vibration suppression control II*, and robust filter are automatically adjusted to maximize your machine performance.
* The advanced vibration suppression control II automatically adjusts one frequency.
Suppress two types of low frequency vibrations at once
Advanced Vibration Suppression Control II


The advanced vibration suppression control II 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 generated at the end of an arm and in a machine, enabling a shorter settling time. Adjustment is easily performed on MR Configurator2.
Wide frequency range
Machine Resonance Suppression Filter

High responsivity and stability
Robust Filter


Achieving both high responsivity and stability was difficult with the conventional control in high-inertia systems with belts and gears such as printing and packaging machines. Now, this function enables the high responsivity and the stability at the same time without adjustment. The robust filter gradually reduces the fluctuation of torque in wide frequency range and achieves more stability as compared to the prior model.
For Changes in Power Supply Environment
Reduce machine downtime
Large Capacity Main Circuit Capacitor

Wide power supply voltage input range
Compatible with 1-phase 200 to 240 V AC Input


Servo amplifiers of 2 kW or smaller are compatible with power supply voltage of 1-phase 200 V AC to 240 V AC.
* When 1-phase 200 V AC to 240 V AC power supply is used with servo amplifiers of 1 kW and 2 kW, use the servo amplifiers with 75% or less of the effective load ratio.
The servo amplifiers of 1 kW and 2 kW cannot be mounted closely when 1-phase power is input.
Reduce undervoltage alarms
Instantaneous Power Failure Tough Drive

A Variety of Positioning Functions
Easy to set a positioning data
Point Table Method
Setting position data (target position), servo motor speed, and acceleration/deceleration time constants in point table is as easy as setting a parameter. Up to 31 points are settable for the point table. The positioning operation is performed with a start signal after selecting the point table No.
Easy operation by program
Program Method*
Create positioning programs with dedicated commands. The positioning operation is performed with a start signal after selecting the program No. The program method enables more complex positioning operation than the point table method. Maximum of 16 programs are settable. (The total number of steps of program: 480)
Easy to create electronic cam
Simple Cam Function
Various patterns of cam data* can be created easily by using MR Configurator2. Command pulse or point table/program start signal can be used as input to the simple cam. The input command will be outputted to the servo motor according to the cam data.
* Cam curve can be selected from 12 types (constant speed/constant acceleration/5th curve/single hypotenuse/cycloid/distorted trapezoid/distorted sine/distorted constant speed/trapecloid/reverse trapecloid/double hypotenuse/reverse double hypotenuse). For details of simple cam function, refer to in the catalog.
Synchronous operation by encoder signal input
Encoder Following Function/Command Pulse Input Through Function
With the encoder following function, the servo amplifier receives A/B-phase output signal from the synchronous encoder as command pulse, and the input command will be outputted to the servo motor according to the cam data. By setting cam data that matches with sheet length, a diameter of the rotary knife axis, and synchronous section of the sheet; a system in which the conveyor axis and the rotary knife axis are synchronized can be configured. Up to 4 Mpulses/s of input from synchronous encoder is compatible with the servo amplifier.
The command pulse input through function allows the first axis to output A/B-phase pulse from the synchronous encoder to the next axis, enabling a system the second and later axes are synchronized with the synchronous encoder.
Compensating a position gap by sensor input
Mark Sensor Input Compensation Function
The actual position of the servo motor can be obtained based on the inputs from the sensor that detects the registration marks printed on the high-speed moving film. The servo amplifier calculates compensation amounts and corrects position errors of the rotary knife axis based on those inputs from the sensor so that the film can be cut at the set position.
Positioning Using Communication Function
Compatible with MODBUS® protocol
Communication Function (MODBUS® RTU)

Easy Monitoring and Maintenance
Analyze cause of alarm
Large Capacity Drive Recorder


● Servo data such as motor current and position command before and after the alarm occurrence are stored in non-volatile memory of the servo amplifier. Reading the servo data on MELSOFT MR Configurator2 helps you analyze the cause of the alarm.
● Check the waveform ((analog 16 bits x 7 channels + digital 8 channels) x 256 points) and the monitor values of 16 alarms in the alarm history.
Reduce machine downtime incurred by age-related deterioration
Vibration Tough Drive

Support optimal maintenance of driving parts
Machine Diagnosis Function


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