"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.

Equipped with built-in regenerative resistor

200W or larger servo amplifier has a built-in regenerative resistor. This space-saving servo amplifier contributes to smaller system configurations.

Large Selection of Servo Motors

Compact high-performance servo motor HF-KN series

● Capacity: 50W to 400W

● By mounting the high-resolution incremental encoder (131072p/rev), both "high-accuracy positioning" and "speed stability in low speed" are enabled.

● Servo motors with electromagnetic brake are also available.

● Cables can be led out either in direction or in opposite direction of the motor shaft according to the selected cables.

● The HF-KN series servo motor is rated IP65 as standard. (excluding the shaft-through portion)

Geared servo motors, HF-KP series, are also available

● Capacity: 50W to 400W

●   ● HF-KP series with reducer are available.

G1: for general industrial machines
G5: flange output type reducer for precision applications
G7: shaft output type reducer for precision applications

These servo motors are flange mounting type.

● Servo motors with electromagnetic brake are also available.

● The HF-KP series with reducer is rated IP44 as standard. (excluding the shaft-through portion)

Equipped with MR-J3-level High Functionality

Extended adjustment functions by the auto tuning

● Advanced vibration suppression control

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.

Setup software "MR Configurator"

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.
