ข้อมูลทั่วไป

 Pursuing of "EASY" for both Operation and Support

Fuss-free Quick tuning with one-touch
Various adjustments for bringing out the full-performance of the servo, such as estimation of load to motor inertia moment ratio, gain adjustment or machine resonance suppression, can be executed automatically with one-touch operation. (Patent pending)





1-phase 100VAC and 200VAC for main circuit power supply
Besides 1-phase 200VAC servo amplifier, 1-phase 100VAC servo amplifier is available.
 * 100VAC servo amplifier is available in 200W or smaller.


Easy power supply wiring without a screwdriver


Easy setting of electronic gear
Calculation of command pulse frequency and travel distance of the ball screw is simple since the number of command pulses per revolution of motor is set to 10000 by default. Additionally, rotation angle is controlled easily just by setting one parameter.

Setting Examples
In the case of the number of command pulses per revolution is set to 10000 (default):

10mm lead ball screw moves 1μm per pulse
(10mm per 10000 pulses)




In the case of the number of command pulses per revolution is set to 36000:


The servo motor rotates 0.01 degrees per pulse.(1 degree per 100 pulses)
*This is when not using a reducer.



Support your inctallation totally
Freeware for capacity calculation
Capacity selection software (MRZJW3-MOTSZ111E) enables optimal selections of servo motor and servo amplifier for your system. This software is available for free download. Contact your local sales office for more details.

 Pursuing "RELIABLE" from the Product Design Phase

  Reliable operation with "tough drive function" *1

● Overload tough drive function
By using the overload tough drive function, machine operation is adjusted automatically to prevent an alarm occurrence when load changes in the machine are detected, and thereby reduces time losses caused by machine stops. (Patent pending)



● Instantaneous power failure tough drive function
When an instantaneous power failure is detected, power charged on the main circuit capacitor is supplied to keep the system running.

* Low voltage alarm may occur depending on the load conditions.



● Vibration tough drive function
This function readjusts the machine resonance suppression filter automatically and prevents resonance when a machine resonance frequency is changed due to aging distortion. Vibration tough drive function


*1 Tough drive function is activated by setting a parameter.


Safe maintenance due to separated power supply for main and control circuits
Because each of the main circuit power supply (1-phase 200VAC or 1-phase 100VAC) and the control circuit power supply (24VDC) has the respective connectors, the main circuit power supply can be turned off separately. It makes the maintenance such as parameter setting or checking of machine status safer when a trouble occurs.


With fanless body
The maintenance performance is improved by eliminating a cooling fan from the servo amplifier. There is no need to worry about the life of the cooling fan.

"Drive recorder function" for quick response to troubleshooting
● This function automatically records data before and after the alarm occurrence.
The recorded data is available in graph even after the power is off. This enables identifying the cause of a trouble and finding its early solution.

● This function selects data automatically to be recorded corresponding to alarms. Information on the causes of alarm is extracted and monitored easily.

* MR Configurator is required to display data in the drive recorder in graph.









"Reduced Setting Space" Makes Your Manufacturing Floor More Comfortable

High performance with small body! Even high-accuracy positioning can be done easily!!

● The servo motor is equipped with high-resolution encoder (131072p/rev), enabling both high-accuracy positioning and speed stability in low speed. The servo amplifier supports 1 Mpps command pulse frequency, realizing high-accuracy positioning. MELSERVO-JN can be used for various applications.

● MR-C series servo amplifier can be replaced easily by the MR-JN since both of these servo amplifiers have the same mounting dimensions.



The servo amplifier can be installed closely with each other.



The MR-JN servo amplifiers can be installed closely with each other.

* The operation environment differs when mounted closely. For details, refer to "Servo Amplifier Specifications" and "Cautions concerning use" in the catalog.

The residual vibration with low frequency (up to 100Hz) is suppressed automatically.

* An optimal filter is set automatically by the auto tuning function.



● Adaptive filter II

High frequency machine resonance can be suppressed automatically by the one-touch tuning. Furthermore, by using the vibration tough drive function, the filter is readjusted automatically when a machine resonance is detected even after the tuning.



Various control modes


● Speed/torque control operation
The speed control mode and the torque control mode are supported. (The speed and the torque commands are set internally by parameters.)


● Torque limit
The torque generated by the servo motor can be controlled by setting parameters.

MR Configurator enables high-speed sampling and long-time waveform measurement.
It makes start up and adjustments of the servo system easier. 
A personal computer can be connected to the servo amplifier via USB.


Conformity with Global Standards

Complied with EN, UL and CSA standards

MELSERVO-JN conforms to the global standards.

*1 This product is not a subject of China Compulsory Certification (CCC).
*2 HF-KN servo motor series will be compatible with EN, UL and CSA standards.


Complied with Restriction of Hazardous Substances Directive (RoHS)

MELSERVO-JN is human and environmental-friendly AC servo compliant with RoHS directive. Additionally, our optional cables and connectors comply with "Measures for Administration of the Pollution Control of Electronic Information Products" (Chinese RoHS).


About RoHS Directive 
RoHS Directive requires member nations to guarantee that new electrical and electronic equipment sold in the market after July 1, 2006 do not contain lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyl (PBB) and polybrominated diphenyl ether (PBDE) flame retardants. mark indicating RoHS Directive compliance is printed on the package.


Built-in positioning function (Note 1)

Positioning without a controller




A simple positioning system can be configured without a controller since the positioning function (point table and program methods) is built into the servo amplifier, saving cost and space.


Point table method

Setting position data (target position), servo motor speed, and acceleration and deceleration time constants in the point table is as easy as setting parameters. 
Up to seven points are available for positioning. Positioning operation is performed after selecting the point table number with an external interface signal.









Program method (Note 2)

Simple positioning program can be created using dedicated commands. A program is executed with a start signal after selecting the program number with an external interface signal. Program method enables more complex positioning operation than point table method. Up to eight programs can be stored in the memory.





Notes:1. Servo amplifier with software version BO or above is required for the positioning function.

2. MR Configurator is required to create a program. MR Configurator with software version C4 or above is compatible with creating a program.
